Method Detail

createCompressorInputStream

CompressorInputStream createCompressorInputStream(String name,
                                                  InputStream in,
                                                  boolean decompressUntilEOF)
                                           throws CompressorException

Creates a compressor input stream from a compressor name and an input stream.

Parameters:

name - of the compressor, i.e. "gz", "bzip2", "xz", "lzma", "pack200", "snappy-raw", "snappy-framed", "z" or "deflate"

in - the input stream

decompressUntilEOF - if true, decompress until the end of the input; if false, stop after the first stream and leave the input position to point to the next byte after the stream. This setting applies to the gzip, bzip2 and xz formats only.

Returns:

compressor input stream

Throws:

CompressorException - if the compressor name is not known

IllegalArgumentException - if the name or input stream is null

createCompressorOutputStream

CompressorOutputStream createCompressorOutputStream(String name,
                                                    OutputStream out)
                                             throws CompressorException

Creates a compressor output stream from an compressor name and an output stream.

Parameters:

name - the compressor name, i.e. "gz", "bzip2", "xz", "pack200" or "deflate"

out - the output stream

Returns:

the compressor output stream

Throws:

CompressorException - if the archiver name is not known

IllegalArgumentException - if the archiver name or stream is null

getInputStreamCompressorNames

Set<String> getInputStreamCompressorNames()

Gets all the input stream compressor names for this provider

Returns:

all the input compressor names for this provider

getOutputStreamCompressorNames

Set<String> getOutputStreamCompressorNames()

Gets all the output stream compressor names for this provider

Returns:

all the output compressor names for this provider
