Class ExecutionContext

public class ExecutionContext
extends Object

This class models an execution context (transaction, security, etc) with which the Work instance must be executed. This class is provided as a convenience for easily creating ExecutionContext instances by extending this class and overriding only those methods of interest.

Some reasons why it is better for ExecutionContext to be a class rather than an interface:
