Method Detail

readAsync

io.netty.buffer.ByteBuf readAsync()
                           throws IOException

Can only be called is isReadable has returned true. If there is data this will return a buffer, otherwise it will return null to indicate EOF

Throws:

IOException

isReadable

boolean isReadable()

Must be called before calling readAsync(). If this returns true then data can be read, if this returns false then a read handler can be registered using setReadHandler(BiConsumer, Object)

Returns:

true if data can be read

setReadHandler

<T> void setReadHandler(BiConsumer<InputChannel,T> handler,
                        T context)

Registers a read handler that will be called when the channel is readable. This handler will only be called once, to continue to read this method must be called every time isReadable() returns false

Type Parameters:

T - The type of the context object

Parameters:

handler - The handler

context - A context object that will be passed to the handler

readBytesAvailable

int readBytesAvailable()

Returns:

The number of bytes that are available to be immediately read

readBlocking

io.netty.buffer.ByteBuf readBlocking()
                              throws IOException

Reads some data. If all data has been read it will return null.

Returns:

Throws:
