Method Detail

getRegionBindings

java.util.List getRegionBindings()

Return a list of all nested RegionBindings contained by this RegionBinding.

getExecutableType

int getExecutableType()

Returns one of an enumeration of Executable binding types in the framework.

int value of 0 is reserved for RegionBinding or BindingContainer type.

getRegionController

RegionController getRegionController()

Returns an instance of RegionController that should handle the lifecycle for this RegionBinding.

By default this will return null. For Regions that have an overridden RegionController defined in the Region definition this will return an instance of the RegionController implementation.

This RegionBinding controller is invoked when this RegionBinding needs to refresh or validate it's contained RegionBindings.

getActionProcessor

java.lang.Object getActionProcessor()

Returns an instance of java bean that may implement event-handling for actions defined on this RegionBinding.

A controller should delegate to this event processor for handling action events for those actions that have a corresponding method. Otherwise controller should invoke the ActionBinding directly.

refresh

void refresh(int flag)

Refresh data for this regionBinding based on the given flag.

isViewable

boolean isViewable()

Consults security to return whether this regionController binding should be visible in the current context or not. It is expected that view technologies will consult this flag before processing region's model.

release

void release(int flags)
