getChildren

public List<ComponentConnector> getChildren()

Description copied from interface: ComponentContainerConnector

Returns the children for this connector.

The children for this connector are defined as all ComponentConnectors whose parent is this ComponentContainerConnector.

Specified by:

getChildren in interface ComponentContainerConnector

Returns:

A collection of children for this connector. An empty collection if there are no children. Never returns null.

setChildren

setChildren in interface ComponentContainerConnector

Parameters:

children - The new child connectors

onConnectorHierarchyChange

public void onConnectorHierarchyChange(ConnectorHierarchyChangeEvent event)

Specified by:

onConnectorHierarchyChange in interface ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler

addConnectorHierarchyChangeHandler

public com.google.gwt.event.shared.HandlerRegistration addConnectorHierarchyChangeHandler(ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler handler)
