extends Object

    1.4

    • Method Detail

      • isXZCompressionAvailable

        public static boolean isXZCompressionAvailable()
        Are the classes required to support XZ compression available?
        Since:
        1.5

      • isCompressedFilename

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

      • getUncompressedFilename

        public static String getUncompressedFilename(String filename)
        Maps the given name of a xz-compressed file to the name that the file should have after uncompression. Commonly used file type specific suffixes like ".txz" are automatically detected and correctly mapped. For example the name "package.txz" is mapped to "package.tar". And any filenames with the generic ".xz" suffix (or any other generic xz suffix) is mapped to a name without that suffix. If no xz 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 xz. Common file types with custom suffixes for compressed versions are automatically detected and correctly mapped. For example the name "package.tar" is mapped to "package.txz". If no custom mapping is applicable, then the default ".xz" suffix is appended to the filename.
        Parameters:
        filename - name of a file
        Returns:
        name of the corresponding compressed file
