Method Details

isCompressedFilename
Detects common bzip2 suffixes in the given file name.- Parameters:
fileName
- name of a file- Returns:
true
if the file name has a common bzip2 suffix,false
otherwise
-
getUncompressedFilename
Maps the given name of a bzip2-compressed file to the name that the file should have after uncompression. Commonly used file type specific suffixes like ".tbz" or ".tbz2" are automatically detected and correctly mapped. For example the name "package.tbz2" is mapped to "package.tar". And any file names with the generic ".bz2" suffix (or any other generic bzip2 suffix) is mapped to a name without that suffix. If no bzip2 suffix is detected, then the file name is returned unmapped.- Parameters:
fileName
- name of a file- Returns:
- name of the corresponding uncompressed file
-
getCompressedFilename
Maps the given file name to the name that the file should have after compression with bzip2. Currently this method simply appends the suffix ".bz2" to the file name based on the standard behavior of the "bzip2" program, but a future version may implement a more complex mapping if a new widely used naming pattern emerges.- Parameters:
fileName
- name of a file- Returns:
- name of the corresponding compressed file
