Enum Constant Summary

Enum Constants

Enum Constant	Description
ELEMENT	Standard namespace for elements of a collection object.
METHOD	Standard namespace for methods of an object.
PROPERTY	Standard namespace for properties of an object.

Method Summary

Modifier and Type	Method	Description
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.
static StandardNamespace	valueOf(String name)	Returns the enum constant of this type with the specified name.
static StandardNamespace[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Methods declared in class java.lang.Enum

Enum Constant Details

PROPERTY

public static final StandardNamespace PROPERTY

Standard namespace for properties of an object.

ELEMENT

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.

Method Details

values

public static StandardNamespace[] 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

public static StandardNamespace 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

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.

Parameters:

op - the operation

Returns:

the first standard namespace in the operation's namespace list
