Enum StandardNamespace

All Implemented Interfaces:
Serializable, Comparable<StandardNamespace>, Namespace
public enum StandardNamespace
extends Enum<StandardNamespace>
implements Namespace

An enumeration of standard namespaces defined by Dynalink.

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.

Methods

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

clone, compareTo, equals, finalize, getDeclaringClass, hashCode, name, ordinal, toString, valueOf

Methods declared in class java.lang.Object

getClass, notify, notifyAll, wait, wait, wait

Enum Constants

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.

Methods

values

public static StandardNamespace[] 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 (StandardNamespace c : StandardNamespace.values())
    System.out.println(c);

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
