Methods

_tick

_tick(): void
Called on each tick/frame to update view manager state.

Returns void

clearViewsWithErrors

clearViewsWithErrors(): void
Clears the list of views with errors.

Returns void

forceInvalidateViewState

forceInvalidateViewState(view: BaseView.BaseView<ViewState, ISGNGroup>): void
Forces the state of the specified view to be marked dirty, then invalidates it. Use when external state changes require getViews() to run even though the view's own state fields did not mutate.
Parameters
- view: BaseView.BaseView<ViewState, ISGNGroup>
  The view whose state should be forcibly invalidated.
Returns void

getViewsWithErrors

getViewsWithErrors(): BaseView.BaseView<ViewState, ISGNGroup>[]
Retrieves all views that currently have errors.

Returns BaseView.BaseView<ViewState, ISGNGroup>[]
An array of views with errors.

invalidateViewLayout

invalidateViewLayout(view: IHosannaView<ViewState>): void
Invalidates the layout of the specified view, causing it to be recalculated.
Parameters
- view: IHosannaView<ViewState>
  The view whose layout should be invalidated.
Returns void

invalidateViewState

invalidateViewState(view: IHosannaView<ViewState>): void
Invalidates the state of the specified view, causing it to be re-rendered or updated.
Parameters
- view: IHosannaView<ViewState>
  The view whose state should be invalidated.
Returns void

registerControlWithError

registerControlWithError(errorObj: IDebugErrorObject, view?: any): void
Registers a control (view) with an error for debugging purposes.
Parameters
- errorObj: IDebugErrorObject
  The error object containing debug information.
- Optionalview: any
  The view associated with the error.
Returns void

registerForCleanup

registerForCleanup(view: IHosannaView<ViewState>): void
Registers a detached view for deferred cleanup at end of the current ViewManager tick. Used when removeSubView must not call release() synchronously (e.g. reconciliation).
Parameters
- view: IHosannaView<ViewState>
Returns void

unregisterControlWithError

unregisterControlWithError(view: any): void
Unregisters a control (view) from error tracking.
Parameters
- view: any
  The view to unregister.
Returns void
