oleccontextAll | Indicates that all state contexts in the state context tree are affected. | |

oleccontextOthers | Indicates that all state contexts outside of the state context of a component manager are affected. |
Remarks
FCreateSubComponentManager() enables the creation of a hierarchical tree of component managers. This tree is used to maintain multiple contexts with regard to the olecstate. These contexts are referred to as state contexts.
Each component manager in the tree defines a state context. The components that are registered with a particular component manager or any of its descendents are part of the state context of that component manager. Calls to OnComponentEnterState() or FOnComponentExitState() can be used to affect all components, only the components that are in the state context of a component manager, or only those components that are outside of the state context of a component manager.
注意
FInState() is used to query the state context of a component manager at its root.
