Method Detail

setLongFileMode

public void setLongFileMode(int longFileMode)

Set the long file mode. This can be LONGFILE_ERROR(0) or LONGFILE_BSD(1). This specifies the treatment of long file names (names >= 16). Default is LONGFILE_ERROR.

Parameters:

longFileMode - the mode to use

closeArchiveEntry

public void closeArchiveEntry()
                       throws IOException

Closes the archive entry, writing any trailer information that may be required.

Specified by:

closeArchiveEntry in class ArchiveOutputStream

Throws:

IOException

putArchiveEntry

public void putArchiveEntry(ArchiveEntry pEntry)
                     throws IOException

Writes the headers for an archive entry to the output stream. The caller must then write the content to the stream and call ArchiveOutputStream.closeArchiveEntry() to complete the process.

Specified by:

putArchiveEntry in class ArchiveOutputStream

Parameters:

pEntry - describes the entry

Throws:

IOException

write

public void write(byte[] b,
                  int off,
                  int len)
           throws IOException

Overrides:

write in class OutputStream

Throws:

IOException

close

public void close()
           throws IOException

Calls finish if necessary, and then closes the OutputStream

Specified by:

close in interface Closeable

Overrides:

close in class OutputStream

Throws:

IOException

createArchiveEntry

public ArchiveEntry createArchiveEntry(File inputFile,
                                       String entryName)
                                throws IOException

Create an archive entry using the inputFile and entryName provided.

Specified by:

createArchiveEntry in class ArchiveOutputStream

Returns:

the ArchiveEntry set up with details from the file

Throws:

IOException

finish

public void finish()
            throws IOException

Finishes the addition of entries to this stream, without closing it. Additional data can be written, if the format supports it. The finish() method throws an Exception if the user forgets to close the entry .
