getNeedRefresh

public boolean getNeedRefresh()

Description copied from interface: IRefreshable

Specified by:

getNeedRefresh in interface IRefreshable

Overrides:

getNeedRefresh in class CSPRefreshableContentBaseProvider

Returns:

true when the output properties are not up-to-date with the current input parameters, i.e. IRefreshable.refresh() needs to be executed manually or automatically.
