Method Detail

getProviderFromName

public TransitionFactory getProviderFromName(java.lang.String type)

method to retrieve the TransitionProvider from a string tag If the tag contains a colon this is taken as a separator between two fields. The first field is used to construct a TransitionFactoryCreator using AppContext.makeObject(Class, String) and the second field is used as the parameter to TransitionFactoryCreator.getTransitionProvider(String). otherwise calls to AppContext.makeObject(Class, String) are attempted with the following tag/type parameters

• TransitionProvider. looking for {link TransitionFactory.
• TargetName looking for TransitionFactory
• TargetName looking for TransitionFactoryCreator

Sub-classes can override this method.

Parameters:

type - TargetName of the TransitionProvider

Returns:

TransitionFactory
