  org.apache.whirr.HandlerMapFactory

Direct Known Subclasses:

DynamicHandlerMapFactory

public class HandlerMapFactory
extends Object

HandlerMapFactory used in ScriptBasedClusterAction classes to create a map of action handlers. This implementation allow reuse of the same handler map by multiple ScriptBasedClusterAction instances. Note: Another motivation of extracting this code outside of ScriptBasedClusterAction is that the same code inside action implementation is not possible to mock by Mockito for JUnit testing purposes. Without this code the action classes can be plugged with another factory and remain JUnit testable.
