public interface TraceClientObserver

Implementations are notified of client configuration updates and stack frame changes by an observed TraceClient.

void	connected(java.lang.String nodeName, java.util.Map<java.lang.Integer,java.lang.String> injectableExceptions) Called when the client is connected
void	disconnected() Called when the client is disconnected
void	stackFrameException(long threadId, java.lang.String description) Called when the previous stack frame ended throwing an exception
void	stackFrameReturn(long threadId) Called when the previous stack frame ended because of a return, not throwing an exception
InjectableException	stackFrameStart(long threadId, java.lang.String threadName, StackFrame stackFrame) Called when a new stack frame starts
