      public static final TextIO.CompressionType UNCOMPRESSED

      Uncompressed (i.e., may be split).

  • Method Detail

    • values

      public static TextIO.CompressionType[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

      for (TextIO.CompressionType c : TextIO.CompressionType.values())
          System.out.println(c);
      

      Returns:

      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static TextIO.CompressionType valueOf(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

      Parameters:

      name - the name of the enum constant to be returned.

      Returns:

      the enum constant with the specified name

      Throws:

      IllegalArgumentException - if this enum type has no constant with the specified name

      NullPointerException - if the argument is null

    • matches

      public boolean matches(String filename)

      Determine if a given filename matches a compression type based on its extension.

      Parameters:

      filename - the filename to match

      Returns:

      true iff the filename ends with the compression type's known extension.
