Examples of org.apache.pig.impl.plan.CompilationMessageCollector$Message

org.eclipse.bpmn2.Message
This class is used for collecting all messages (error + warning) in compilation process. These messages are reported back to users at the end of compilation. iterator() has to be called after CompilationMessageCollector is fully populated otherwise the state is undefined.
