Examples of org.apache.axiom.testutils.InvocationCounter

org.apache.axiom.testutils.InvocationCounter
Utility class that counts the number of invocations on one or more objects. It also counts the number of exceptions thrown by these invocations. The class uses dynamic proxies to implement this feature.
This class is thread safe.
