• Enum Constant Details

  • PROPERTY

  Standard namespace for properties of an object.

  • ELEMENT

  Standard namespace for elements of a collection object.

  • METHOD

  Standard namespace for methods of an object. The method objects retrieved through a StandardOperation.GET on this namespace can be (and where object semantics allows they should be) unbound, that is: not bound to the object they were retrieved through. When they are used withStandardOperation.CALL an explicit "this" receiver argument is always passed to them. Of course bound methods can be returned if the object semantics requires them and such methods are free to ignore the receiver passed in theCALL operation or even raise an error when it is different from the one the method is bound to, or exhibit any other behavior their semantics requires in such case.

• Method Details

  • values

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

  • valueOf

  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](../../../java.base/java/lang/IllegalArgumentException.html "class in java.lang") - if this enum type has no constant with the specified name
  [NullPointerException](../../../java.base/java/lang/NullPointerException.html "class in java.lang") - if the argument is null

  • findFirst

  If the passed in operation is a NamespaceOperation, or aNamedOperation wrapping a NamespaceOperation, then it returns the first (if any) StandardNamespace in its namespace list. If the passed operation is not a namespace operation (optionally wrapped in a named operation), or if it doesn't have any standard namespaces in it, returns null.
  Parameters:
  op - the operation
  Returns:
  the first standard namespace in the operation's namespace list
