Method Detail

get

public static CompressionFormat get()

Required by CompressionFormatFactory.

getName

public java.lang.String getName()

Specified by:

getName in interface CompressionFormat

Returns:

A short, familiar text which describes this compression format, e.g. 'bzip2', 'gz', 'z'

isCompressedFileName

public boolean isCompressedFileName(java.lang.String fileName)

Specified by:

isCompressedFileName in interface CompressionFormat

Returns:

Whether the given fileName is typical for this CompressionFormat

getCompressedFileName

public java.lang.String getCompressedFileName(java.lang.String fileName)

Description copied from interface: CompressionFormat

Maps the given fileName to the name that a corresponding compressed file would have. This is typically achieved by appending a suffix, like '.bzip2', '.gz', '.Z'.

Specified by:

getCompressedFileName in interface CompressionFormat

getUncompressedFileName

public java.lang.String getUncompressedFileName(java.lang.String fileName)

Description copied from interface: CompressionFormat

Maps the given fileName to the name that a corresponding uncompressed file would have. This is typically achieved by removing a suffix, like '.bzip2', '.gz', '.Z', or by changing the suffix, e.g. from '.tgz' to '.tar'.

Specified by:

getUncompressedFileName in interface CompressionFormat

compressorInputStream

public org.apache.commons.compress.compressors.CompressorInputStream compressorInputStream(java.io.InputStream is)
                                                                                    throws java.io.IOException

Specified by:

compressorInputStream in interface CompressionFormat

Returns:

A CompressorInputStream for this format which reads from the given input stream

Throws:

java.io.IOException

open

public org.apache.commons.compress.compressors.CompressorInputStream open(java.io.File compressedFile)
                                                                   throws java.io.IOException

Description copied from interface: CompressionFormat

Opens an existing compressed file for reading.

Specified by:

open in interface CompressionFormat

Returns:

An CompressorInputStream for this format which reads from the given compressedFile

Throws:

java.io.IOException

compressorOutputStream

public org.apache.commons.compress.compressors.CompressorOutputStream compressorOutputStream(java.io.OutputStream os)
                                                                                      throws org.apache.commons.compress.compressors.CompressorException

Specified by:

compressorOutputStream in interface CompressionFormat

Returns:

An CompressorOutputStream for this format which writes to the given output stream

Throws:

org.apache.commons.compress.compressors.CompressorException - Creation of compressed contents in in this format is not supported

create

public org.apache.commons.compress.compressors.CompressorOutputStream create(java.io.File compressedFile)
                                                                      throws org.apache.commons.compress.compressors.CompressorException

Description copied from interface: CompressionFormat

Creates a new compressed file.

Specified by:

create in interface CompressionFormat

Returns:

An CompressorOutputStream for this format which writes to the given compressedFile

Throws:

org.apache.commons.compress.compressors.CompressorException - Creation of compressed files in in this format is not supported

matches

public boolean matches(byte[] signature,
                       int signatureLength)

Specified by:

matches in interface CompressionFormat

Returns:

Whether the first few bytes of compressed data match what is expected for this format

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
