Method Detail

registerNewObjectListener

public void registerNewObjectListener(NewObjectListener listener,
                                      Class<?> type)

Registers a NewObjectListener. The listener will be called with each newly-created object of the given type. If type is null, then the listener will be called for each new object.

registerMessageListener

public void registerMessageListener(LogtoolContext listener,
                                    Class<?> type)

Registers the given LogtoolContext as a messageListener. Incoming messages must be dispatched using util.MessageDispatcher

readObject

public Object readObject(String line)
                  throws MissingDomainObject

Converts a line from the log to an object. Each line is of the form
ms:class::id::method{::arg}* Note that some objects cannot be resolved in the order they appear in a logfile, because they have forward dependencies. This means that a failure to resolve an object does not necessarily mean it's bogus, but could mean that it could be resolved at a later time, typically within one or a very few input lines.

Throws:

MissingDomainObject

getById

public Object getById(long id)
