Interface Registry<T>

Type Parameters:

T - the type of objects that can be registered

All Superinterfaces:

java.lang.Iterable<Registration<? extends T>>

All Known Implementing Classes:

CachingRegistry

public interface Registry<T>
extends java.lang.Iterable<Registration<? extends T>>

Implementations of this interface manage a registry of objects that works sort of like a Map, except Registries don't use simple keys, they use Selectors to map their objects.

Method Summary

Modifier and Type	Method and Description
void	clear() Clear the Registry, resetting its state and calling Registration.cancel() for any active Registration.
<V extends T> Registration<V>	register(Selector sel, V obj) Assign the given Selector with the given object.
java.util.List<Registration<? extends T>>	select(java.lang.Object key) Select Registrations whose Selector Selector.matches(Object) the given key.
boolean	unregister(java.lang.Object key) Remove any objects matching this key.

Method Detail

Remove any objects matching this key. This will unregister all objects matching the given key. There's no provision for removing only a specific object.

Parameters:

key - The key to be matched by the Selectors

Returns:

true if any objects were unassigned, false otherwise.

select

java.util.List<Registration<? extends T>> select(java.lang.Object key)

Select Registrations whose Selector Selector.matches(Object) the given key.

Parameters:

key - The key for the Selectors to match

Returns:

A List of Registrations whose Selector matches the given key.

clear

void clear()
