Inner Class :public class Result implements Serializable


Constructor Summary
public  MethodInvocationBatch()
     Create a new empty method invocation batch.
public  MethodInvocationBatch(boolean stopOnException)
     Create a new empty method invocation batch.

Method Summary
public  voidaddInvocation(Object obj, String method, String[] argTypes, Object[] args)
     Adds a method invocation to the batch.
Parameters:
  obj - the objects whose method is to be invoked.
Parameters:
  method - the method name.
Parameters:
  argTypes - the argument types as strings suitable forClassLoader.loadClass.
public  voidaddInvocation(int result, String method, String[] argTypes, Object[] args, boolean discard)
     Adds a method invocation on a previous result to the batch.
public  Objectexecute(Context ctx)
     Executes the registered method invocations one by one in a single transaction.


Constructor Detail
