Enum CompressionValue

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<CompressionValue>

    public enum CompressionValue
    extends java.lang.Enum<CompressionValue>
    Enumerates the possible compression values for TIFF images.

    • Method Detail

      • values

        public static CompressionValue[] 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 (CompressionValue c : CompressionValue.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static CompressionValue valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
      • getValue

        public static CompressionValue getValue​(java.lang.String name)
        Gets the compression value given the name of the compression type.
        Parameters:
        name - the compression name
        Returns:
        the compression value
