  • Method Details

    • getCompressedFilename

      @Deprecated 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
    • 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

      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)
      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

      Parameters:
      fileName - name of a file
      Returns:
      true if the file name has a common gzip suffix, false otherwise
