      • matches

        public static boolean matches(byte[] signature,              int length)
        Checks if the signature matches what is expected for a .lzma file.
        Parameters:
        signature - the bytes to check
        length - the number of bytes to check
        Returns:
        true if signature matches the .lzma magic bytes, false otherwise
      • isLZMACompressionAvailable

        public static boolean isLZMACompressionAvailable()
        Are the classes required to support LZMA compression available?
        Returns:
        true if the classes required to support LZMA compression are available
      • isCompressedFilename

        public static boolean isCompressedFilename(String filename)
        Detects common lzma suffixes in the given filename.
        Parameters:
        filename - name of a file
        Returns:
        true if the filename has a common lzma suffix, false otherwise
      • getUncompressedFilename

        public static String getUncompressedFilename(String filename)
        Maps the given name of a lzma-compressed file to the name that the file should have after uncompression. Any filenames with the generic ".lzma" suffix (or any other generic lzma suffix) is mapped to a name without that suffix. If no lzma suffix is detected, then the filename is returned unmapped.
        Parameters:
        filename - name of a file
        Returns:
        name of the corresponding uncompressed file
      • getCompressedFilename

        public static String getCompressedFilename(String filename)
        Maps the given filename to the name that the file should have after compression with lzma.
        Parameters:
        filename - name of a file
        Returns:
        name of the corresponding compressed file
      • setCacheLZMAAvailablity

        public static void setCacheLZMAAvailablity(boolean doCache)
        Whether to cache the result of the LZMA check.

        This defaults to false in an OSGi environment and true otherwise.

        Parameters:
        doCache - whether to cache the result
