,InternalWrapperContext
public final class InternalContextAdapterImpl extends Object implements InternalContextAdapter
This adapter class is the container for all context types for internal use. The AST now uses this class rather than the app-level Context interface to allow flexibility in the future. Currently, we have two context interfaces which must be supported :- Context : used for application/template data access
- InternalHousekeepingContext : used for internal housekeeping and caching
- InternalWrapperContext : used for getting root cache context and other such.
- InternalEventContext : for event handling.
