Method Details

getHandle

public <E extends T> ListenerHandle<E> getHandle(Class<E> handleType)

Description copied from interface: EventNode

Gets the handle of an event type.

Specified by:

getHandle in interface EventNode<T extends Event>

Type Parameters:

E - the event type

Parameters:

handleType - the handle type

Returns:

the handle linked to handleType

findChildren

public <E extends T> List<EventNode<E>> findChildren(String name,
 Class<E> eventType)

Description copied from interface: EventNode

Locates all child nodes with the given name and event type recursively starting at this node.

Specified by:

findChildren in interface EventNode<T extends Event>

Parameters:

name - The event node name to filter for

eventType - The event node type to filter for

Returns:

All matching event nodes

getChildren

@Contract(pure=true)
public Set<EventNode<Event>> getChildren()

Description copied from interface: EventNode

Returns an unmodifiable view of the children in this node.

Specified by:

getChildren in interface EventNode<T extends Event>

See Also:

• EventNode.addChild(EventNode)
• EventNode.removeChild(EventNode)

replaceChildren

public <E extends T> void replaceChildren(String name,
 Class<E> eventType,
 EventNode<E> eventNode)

Description copied from interface: EventNode

Replaces all children matching the given name and type recursively starting from this node.

Node: The callee may not be replaced by this call.

Specified by:

replaceChildren in interface EventNode<T extends Event>

Parameters:

name - The event name to filter for

eventType - The event node type to filter for

eventNode - The replacement node

removeChildren

public void removeChildren(String name,
 Class<? extends Event> eventType)

Description copied from interface: EventNode

Recursively removes children with the given name and type starting at this node.

Specified by:

removeChildren in interface EventNode<T extends Event>

Parameters:

name - The node name to filter for

eventType - The node type to filter for

addChild

public EventNode<Event> addChild(EventNode<? extends Event> child)

Description copied from interface: EventNode

Directly adds a child node to this node.

Specified by:

addChild in interface EventNode<T extends Event>

Parameters:

child - The child to add

Returns:

this, can be used for chaining

removeChild

public EventNode<Event> removeChild(EventNode<? extends Event> child)

Description copied from interface: EventNode

Directly removes the given child from this node.

Specified by:

removeChild in interface EventNode<T extends Event>

Parameters:

child - The child to remove

Returns:

this, can be used for chaining

addListener

public EventNode<Event> addListener(EventListener<? extends Event> listener)

Specified by:

addListener in interface EventNode<T extends Event>

removeListener

public EventNode<Event> removeListener(EventListener<? extends Event> listener)

Specified by:

removeListener in interface EventNode<T extends Event>

map

public <E extends T, H> EventNode<E> map(H value,
 EventFilter<E,H> filter)

Description copied from interface: EventNode

Maps a specific object to a node.

Be aware that such structure have huge performance penalty as they will always require a map lookup. Use only at last resort.

Specified by:

map in interface EventNode<T extends Event>

Parameters:

value - the mapped value

filter - the filter to use

Returns:

the node (which may have already been registered) directly linked to value

unmap

Prevents the node from EventNode.map(Object, EventFilter) to be called.

Specified by:

unmap in interface EventNode<T extends Event>

Parameters:

value - the value to unmap

register

public void register(EventBinding<? extends Event> binding)

Specified by:

register in interface EventNode<T extends Event>

unregister
