toString

public String toString()

Overrides:

toString in class Object

debugState

public Object debugState()

Description copied from interface: DebugState

Returns an object that will be toStringed when the debug information needs to be printed. This method will only be called when the information is to be printed out - which will be rare. This method may safely be slow. It is also ok for the value that would be returned to change over time, even after the time that it is intially set in ThreadDebugState.

The most common implementation is to create a new Map and set key and value pairs of information in that Map which it will then return.

Specified by:

debugState in interface DebugState

Returns:

an object that encapsulates the state of the current application. The toString() method of the returned object should be made safe even if the object that implements DebugState is being modified at the time. Exceptions from toString are tollerable in this case, but data corruption is not.
