  • Constructor Details

    • KeyUsage

      protected KeyUsage(String code, String name)
      Internal constructor.

      The constructor is protected to guarantee only one instance of the key usage in the entire JVM. This makes it possible to use the operator == or != as it does for enums.

      Parameters:
      code - the key usage code
      name - the usage name

  • Method Details

    • getCode

      public String getCode()
      Get key usage code.
      Returns:
      two characters which represents key usage code

    • getName

      public String getName()
      Get key usage name.
      Returns:
      the key usage name

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • valueOfByCode

      public static KeyUsage valueOfByCode(String code)
      Returns the enum constant of this type with the specified code.
      Parameters:
      code -
      Returns:
      the enum constant with the specified processing code or null if unknown.
