- ## Method Details

  - ### getCompressedFilename

    @Deprecated public static String getCompressedFilename(String fileName)
    Deprecated.
    Use `getCompressedFileName(String)`.
    Maps the given file name to the name that the file should have after compression with gzip. 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.tgz". If no custom mapping is applicable, then the default ".gz" suffix is appended to the file name.
    Parameters:
      `fileName` - name of a file
    Returns:
      name of the corresponding compressed file

  - ### getCompressedFileName

    public static String getCompressedFileName(String fileName)
    Maps the given file name to the name that the file should have after compression with gzip. 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.tgz". If no custom mapping is applicable, then the default ".gz" suffix is appended to the file name.
    Parameters:
      `fileName` - name of a file
    Returns:
      name of the corresponding compressed file
    Since:
      1.25.0

  - ### getUncompressedFilename

    @Deprecated public static String getUncompressedFilename(String fileName)
    Deprecated.
    Use `getUncompressedFileName(String)`.
    Maps the given name of a gzip-compressed file to the name that the file should have after uncompression. Commonly used file type specific suffixes like ".tgz" or ".svgz" are automatically detected and correctly mapped. For example the name "package.tgz" is mapped to "package.tar". And any file names with the generic ".gz" suffix (or any other generic gzip suffix) is mapped to a name without that suffix. If no gzip suffix is detected, then the file name is returned unmapped.
    Parameters:
      `fileName` - name of a file
    Returns:
      name of the corresponding uncompressed file

  - ### getUncompressedFileName

    public static String getUncompressedFileName(String fileName)
    Maps the given name of a gzip-compressed file to the name that the file should have after uncompression. Commonly used file type specific suffixes like ".tgz" or ".svgz" are automatically detected and correctly mapped. For example the name "package.tgz" is mapped to "package.tar". And any file names with the generic ".gz" suffix (or any other generic gzip suffix) is mapped to a name without that suffix. If no gzip suffix is detected, then the file name is returned unmapped.
    Parameters:
      `fileName` - name of a file
    Returns:
      name of the corresponding uncompressed file
    Since:
      1.25.0

  - ### isCompressedFilename

    @Deprecated public static boolean isCompressedFilename(String fileName)
    Deprecated.
    Use `isCompressedFileName(String)`.
    Detects common gzip suffixes in the given file name.
    Parameters:
      `fileName` - name of a file
    Returns:
      `true` if the file name has a common gzip suffix, `false` otherwise

  - ### isCompressedFileName

    public static boolean isCompressedFileName(String fileName)
    Detects common gzip suffixes in the given file name.
    Parameters:
      `fileName` - name of a file
    Returns:
      `true` if the file name has a common gzip suffix, `false` otherwise
    Since:
      1.25.0
