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. |

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
