Class ContextManager

java.lang.Object
  org.iqual.chaplin.ContextManager

public class ContextManager
extends Object

This class is the main link between the injected code and context handlers. The injected code directly calls various static methods on this class. For example, this class associates a context with the current thread, manages multiple contexes and retrieves the current context for a given context id.
