Class ComponentRegistry

java.lang.Object

org.patternfly.component.ComponentRegistry

public class ComponentRegistry
extends Object

Public, type-keyed singleton registry for PatternFly components that exist at most once per page. Use this class to register and look up global components such as Page, Masthead, or NotificationDrawerList.

This is distinct from ComponentStore, which is an internal, package-private store for wiring parent-child relationships via DOM traversal and supports multiple instances of the same ComponentType.

Registration is done by calling registerComponent(ComponentType, BaseComponent) or

invalid reference

#registerSubComponent(ComponentType, String, SubComponent)

. Lookup is done by calling lookupComponent(ComponentType) and lookupSubComponent(ComponentType, String). When a registered component is removed from the DOM, call

invalid reference

#unregisterComponent(ComponentType)

or

invalid reference

#unregisterSubComponent(ComponentType, String)

to prevent stale references.
