Enum Class StandardNamespace

All Implemented Interfaces:
Serializable, Comparable<StandardNamespace>, Constable, Namespace

public enum StandardNamespace extends Enum<StandardNamespace> implements Namespace
An enumeration of standard namespaces defined by Dynalink.
  • Enum Constant Details


      public static final StandardNamespace PROPERTY
      Standard namespace for properties of an object.

      public static final StandardNamespace ELEMENT
      Standard namespace for elements of a collection object.
    • METHOD

      public static final StandardNamespace 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 with StandardOperation.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 the CALL 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.

    • values

      public static StandardNamespace[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      an array containing the constants of this enum class, in the order they are declared
    • valueOf

      public static StandardNamespace valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      name - the name of the enum constant to be returned.
      the enum constant with the specified name
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
    • findFirst

      public static StandardNamespace findFirst(Operation op)
      If the passed in operation is a NamespaceOperation, or a NamedOperation 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.
      op - the operation
      the first standard namespace in the operation's namespace list
