```
public final HeapBuffer reset()
```
    Description copied from interface: Buffer
    
    Resets this buffer's position to the previously-marked position.
    Invoking this method neither changes nor discards the mark's value.

    Returns:
    This buffer
  - clear
```
public final HeapBuffer clear()
```
    Description copied from interface: Buffer
    Clears this buffer. The position is set to zero, the limit is set to the capacity, and the mark is discarded.
    Invoke this method before using a sequence of channel-read or put operations to fill this buffer. For example:
    buf.clear(); // Prepare buffer for reading in.read(buf); // Read data
    This method does not actually erase the data in the buffer, but it is named as if it did because it will most often be used in situations in which that might as well be the case.
    Specified by:
    
    clear in interface Buffer
    
    Returns:
    This buffer
  - flip
```
public final HeapBuffer flip()

    Description copied from interface: Buffer
    Flips this buffer. The limit is set to the current position and then the position is set to zero. If the mark is defined then it is discarded.
    After a sequence of channel-read or put operations, invoke this method to prepare for a sequence of channel-write or relative get operations. For example:
    buf.put(magic); // Prepend header in.read(buf); // Read data into rest of buffer buf.flip(); // Flip buffer out.write(buf); // Write header + data to channel
    This method is often used in conjunction with the compact method when transferring data from one place to another.
    Specified by:
    
    flip in interface Buffer
    
    Returns:
    This buffer
  - rewind
```
public final HeapBuffer rewind()
```
    Description copied from interface: Buffer
    Rewinds this buffer. The position is set to zero and the mark is discarded.
    Invoke this method before a sequence of channel-write or get operations, assuming that the limit has already been set appropriately. For example:
    out.write(buf); // Write remaining data buf.rewind(); // Rewind buffer buf.get(array); // Copy data into array
    Specified by:
    
    rewind in interface Buffer
    
    Returns:
    This buffer

```
public final boolean isDirect()
```
    Description copied from interface: Buffer
    
    Tells whether or not this buffer is direct.
    
    Specified by:

    true if, and only if, this buffer is direct
  - split
```
public Buffer split(int splitPosition)
```
    Split up the buffer into two parts: [0..splitPosition) and [splitPosition, capacity). This Buffer will represent the first part: [0..splitPosition) and returned Buffer will represent the second part: [splitPosition, capacity).
    
    Specified by:
    
    split in interface Buffer
    
    Parameters:
    splitPosition - position of split.

  - slice
```
public HeapBuffer slice()
```
    Description copied from interface: Buffer
    
    Creates a new Buffer whose content is a shared subsequence of this buffer's content.
    The content of the new buffer will start at this buffer's current position. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.
    The new buffer's position will be zero, its capacity and its limit will be the number of bytes remaining in this buffer, and its mark will be undefined. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.
    
    Specified by:
    
    slice in interface Buffer
    
    Returns:
    The new Buffer
  - slice
```
public HeapBuffer slice(int position,
               int limit)
```
    Description copied from interface: Buffer
    
    Creates a new Buffer whose content is a shared subsequence of this buffer's content.
    The content of the new buffer will start at passed position and end at passed limit. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffer's position, limit, and mark values will be independent.
    The new buffer's position will be zero, its capacity and its limit will be the number of bytes remaining in this buffer, and its mark will be undefined. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.
    
    Specified by:
    
    slice in interface Buffer
    
    Returns:
    The new Buffer
  - duplicate
```
public HeapBuffer duplicate()
```
    Description copied from interface: Buffer
    
    Creates a new Buffer that shares this buffer's content.
    The content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffer's position, limit, and mark values will be independent.
    The new buffer's capacity, limit, position, and mark values will be identical to those of this buffer. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.
    
    Specified by:
    
    duplicate in interface Buffer
    
    Returns:
    The new Buffer
  - asReadOnlyBuffer
```
public HeapBuffer asReadOnlyBuffer()
```
    Description copied from interface: Buffer
    
    Creates a new, read-only Buffer that shares this buffer's content.
    The content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer; the new buffer itself, however, will be read-only and will not allow the shared content to be modified. The two buffer's position, limit, and mark values will be independent.
    The new buffer's capacity, limit, position, and mark values will be identical to those of this buffer.
    If this buffer is itself read-only then this method behaves in exactly the same way as the duplicate method.
    
    Specified by:
    
    asReadOnlyBuffer in interface Buffer
    
    Returns:
    The new, read-only Buffer

```
public HeapBuffer put(int index,
             byte b)
```
    Description copied from interface: Buffer
    
    Absolute put method (optional operation).
    Writes the given byte into this buffer at the given index.
    
    Specified by:
    
    put in interface Buffer
    
    Parameters:

    This buffer
  - get
```
public HeapBuffer get(byte[] dst)
```
    Description copied from interface: Buffer
    Relative bulk get method.
    This method transfers bytes from this buffer into the given destination array. An invocation of this method of the form src.get(a) behaves in exactly the same way as the invocation
```
     src.get(a, 0, a.length) 
```
    Specified by:
    
    get in interface Buffer
    
    Returns:
    This buffer
  - get
```
public HeapBuffer get(byte[] dst,
             int offset,
             int length)
```
    Description copied from interface: Buffer
    Relative bulk get method.
    This method transfers bytes from this buffer into the given destination array. If there are fewer bytes remaining in the buffer than are required to satisfy the request, that is, if length > remaining(), then no bytes are transferred and a BufferUnderflowException is thrown.
    Otherwise, this method copies length bytes from this buffer into the given array, starting at the current position of this buffer and at the given offset in the array. The position of this buffer is then incremented by length.
    In other words, an invocation of this method of the form src.get(dst, off, len) has exactly the same effect as the loop
```
     for (int i = off; i < off + len; i++)
         dst[i] = src.get(); 
```
    except that it first checks that there are sufficient bytes in this buffer and it is potentially much more efficient.
    Specified by:
    
    get in interface Buffer
    
    Parameters:
    dst - The array into which bytes are to be written
    offset - The offset within the array of the first byte to be written; must be non-negative and no larger than dst.length
    length - The maximum number of bytes to be written to the given array; must be non-negative and no larger than dst.length - offset
    
    Returns:
    This buffer
  - put
```
public HeapBuffer put(Buffer src)
```
    Description copied from interface: Buffer
    Relative bulk put method (optional operation).
    This method transfers the bytes remaining in the given source buffer into this buffer. If there are more bytes remaining in the source buffer than in this buffer, that is, if src.remaining() > remaining(), then no bytes are transferred and a BufferOverflowException is thrown.
    Otherwise, this method copies n = src.remaining() bytes from the given buffer into this buffer, starting at each buffer's current position. The positions of both buffers are then incremented by n.
    In other words, an invocation of this method of the form dst.put(src) has exactly the same effect as the loop

public HeapBuffer put(Buffer src,
             int position,
             int length)
```
    Description copied from interface: Buffer
    Relative bulk put method (optional operation).
    This method transfers the "length" bytes from the given source buffer into this buffer. If this buffer has less bytes remaining than length, that is, if length > remaining(), then no bytes are transferred and a BufferOverflowException is thrown.
    Otherwise, this method copies n = length bytes from the given postion in the source buffer into this buffer, starting from the current buffer position. The positions of this buffer is then incremented by length.
    In other words, an invocation of this method of the form dst.put(src, position, length) has exactly the same effect as the loop
```
     for (int i = 0; i < length; i++)
         dst.put(src.get(i + position)); 
```
    except that it first checks that there is sufficient space in this buffer and it is potentially much more efficient.
    Specified by:
    
    put in interface Buffer
    
    Parameters:
    src - The source buffer from which bytes are to be read; must not be this buffer
    position - starting position in the source buffer
    length - number of bytes to be copied
    
    Returns:

  - get
```
public Buffer get(ByteBuffer dst)
```
    Description copied from interface: Buffer
    Relative bulk get method.
    This method transfers bytes from this buffer into the given destination ByteBuffer. An invocation of this method of the form src.get(a) behaves in exactly the same way as the invocation
```

```
    Specified by:
    
    get in interface Buffer
    
    Returns:
    This buffer

public Buffer get(ByteBuffer dst,
         int position,
         int length)
```
    Description copied from interface: Buffer
    Relative bulk get method.
    This method transfers bytes from this buffer into the given destination ByteBuffer. If there are fewer bytes remaining in the buffer than are required to satisfy the request, that is, if length > remaining(), then no bytes are transferred and a BufferUnderflowException is thrown.
    Otherwise, this method copies length bytes from this buffer into the given ByteBuffer, starting at the current position of this buffer and at the given offset in the ByteBuffer. The position of this buffer is then incremented by length.
    In other words, an invocation of this method of the form src.get(dst, off, len) has exactly the same effect as the loop
```
     for (int i = off; i < off + len; i++)
         dst.put(i) = src.get(); 
```
    except that it first checks that there are sufficient bytes in this buffer and it is potentially much more efficient.
    Specified by:
    
    get in interface Buffer
    
    Parameters:
    dst - The ByteBuffer into which bytes are to be written
    position - The offset within the ByteBuffer of the first byte to be written; must be non-negative and no larger than dst.remaining()
    length - The maximum number of bytes to be written to the given array; must be non-negative and no larger than dst.remaining() - offset
    
    Returns:
    This buffer
  - put
```
public Buffer put(ByteBuffer src)
```
    Description copied from interface: Buffer
    Relative bulk put method (optional operation).
    This method transfers the bytes remaining in the given source buffer into this buffer. If there are more bytes remaining in the source buffer than in this buffer, that is, if src.remaining() > remaining(), then no bytes are transferred and a BufferOverflowException is thrown.
    Otherwise, this method copies n = src.remaining() bytes from the given buffer into this buffer, starting at each buffer's current position. The positions of both buffers are then incremented by n.
    In other words, an invocation of this method of the form dst.put(src) has exactly the same effect as the loop
```

             int length)
```
    Description copied from interface: Buffer
    Relative bulk put method (optional operation).
    This method transfers bytes into this buffer from the given source array. If there are more bytes to be copied from the array than remain in this buffer, that is, if length > remaining(), then no bytes are transferred and a BufferOverflowException is thrown.
    Otherwise, this method copies length bytes from the given array into this buffer, starting at the given offset in the array and at the current position of this buffer. The position of this buffer is then incremented by length.
    In other words, an invocation of this method of the form dst.put(src, off, len) has exactly the same effect as the loop
```
     for (int i = off; i < off + len; i++)
         dst.put(a[i]);

  - put8BitString
```
public HeapBuffer put8BitString(String s)
```
    Description copied from interface: Buffer
    Relative bulk put method (optional operation).
    This method transfers bytes into this buffer from the given 8-bit source String. If the source String.length() is bigger than this buffer's remaining, that is, if length() > remaining(), then no bytes are transferred and a BufferOverflowException is thrown.
    Otherwise, this method copies length bytes from the given String into this buffer.
    In other words, an invocation of this method of the form dst.put8BitString(src) has exactly the same effect as the loop
```
     for (int i = 0; i < src.length(); i++)
         dst.put((byte) src.charAt(i)); 
```
    except that it first checks that there is sufficient space in this buffer and it is potentially much more efficient.
    Specified by:
    
    put8BitString in interface Buffer
    
    Parameters:
    s - The String from which bytes are to be read
    
    Returns:
    This buffer
  - compact
```
public HeapBuffer compact()
```
    Description copied from interface: Buffer
    Compacts this buffer (optional operation).
    The bytes between the buffer's current position and its limit, if any, are copied to the beginning of the buffer. That is, the byte at index p = position() is copied to index zero, the byte at index p + 1 is copied to index one, and so forth until the byte at index limit() - 1 is copied to index n = limit() - 1 - p. The buffer's position is then set to n+1 and its limit is set to its capacity. The mark, if defined, is discarded.
    The buffer's position is set to the number of bytes copied, rather than to zero, so that an invocation of this method can be followed immediately by an invocation of another relative put method.
    
    Invoke this method after writing data from a buffer in case the write was incomplete. The following loop, for example, copies bytes from one channel to another via the buffer buf:
    buf.clear(); // Prepare buffer for use for (;;) { if (in.read(buf) < 0 && !buf.hasRemaining()) break; // No more bytes to transfer buf.flip(); out.write(buf); buf.compact(); // In case of partial write }
    Specified by:
    
    compact in interface Buffer
    
    Returns:
    This buffer

If this Buffer is not composite - then returned ByteBuffer's content is a shared subsequence of this buffer's content, with CompositeBuffer this is not guaranteed. The position of the returned ByteBuffer is not guaranteed to be 0, the capacity of the returned ByteBuffer is not guaranteed to be equal to the capacity of this Buffer. It is guaranteed that the result of the returned ByteBuffer's Buffer.remaining() call will be equal to this Buffer's Buffer.remaining() call. The Buffer's and ByteBuffer's position, limit, and mark values are not guaranteed to be independent, so it's recommended to save and restore position, limit values if it is planned to change them or ByteBuffer.slice() the returned ByteBuffer.
    
    Specified by:
    
    toByteBuffer in interface Buffer
    
    Returns:
    this Buffer as a ByteBuffer.

```
    Converts this Buffer to a ByteBuffer. If this Buffer is not composite - then returned ByteBuffer's content is a shared subsequence of this buffer's content, with CompositeBuffer this is not guaranteed. The position of the returned ByteBuffer is not guaranteed to be 0, the capacity of the returned ByteBuffer is not guaranteed to be equal to the capacity of this Buffer. It is guaranteed that the result of the returned ByteBuffer's Buffer.remaining() call will be equal (limit - position).
