                 throws DIException

Register a listener for AssemblyLine events. You must be admin to execute this method. Beware that there is no automatic removal of orphaned listeners.

Specified by:

addListener in interface AssemblyLine

Parameters:

listener - Listener for AssemblyLine events.

getLogs - If true, the listener will receive logged messages.

getEntryOnEachCycle - If true the listener will receive the current entry at each AssemblyLine cycle's end.

Throws:

DIException - If the listener cannot be registered.

See Also:

AssemblyLine.removeListener(AssemblyLineListener)

removeListener

public void removeListener(AssemblyLineListener listener)
                    throws DIException

Unregister a listener for AssemblyLine events. You must be admin to execute this method. Listeners are associated with the API object, not with the AssemblyLine in the Server, so you can remove only listeners added with the #addListener(AssemblyLineListener, boolean) method on the same object.

Beware that the listener may get notified one more time after it was unregistered. The only way to ensure this does not happen is to unregister the listener in one of its callback methods.

Specified by:

removeListener in interface AssemblyLine

Parameters:

listener - The listener that needs to be removed.

Throws:

DIException - If the listener cannot be unregistered.

See Also:

#addListener(AssemblyLineListener, boolean)

                    throws DIException

Attach a debugger to the AssemblyLine. You must be admin to execute this method.

Specified by:

attachDebugger in interface AssemblyLine

Parameters:

port - Port of the debugger.

host - Host of the debugger.

onerror - If true breakpoints are disabled except when there is an error.

Throws:

DIException - If the AssemblyLine is already being debugged or the AssemblyLine cannot connect to the debugger.

detachDebugger

public void detachDebugger(Object msg)
                    throws DIException

Detach the current debugger from the AssemblyLine. You must be admin to execute this method.

Specified by:

Throws:

DIException - If an error occurs while detaching the debugger.

                           throws DIException

Modify the debug mode setting of the specified component (Connector or Function Component). You must be admin to execute this method. Modifications are done on the fly and are not persisted in the configuration - AssemblyLine.getConfig(). If you run the same AssemblyLine again it will use the settings from the configuration.

Specified by:

setComponentDebugMode in interface AssemblyLine

Parameters:

componentName - The name of a Connector or a Function Component from this AssemblyLine.

debug - The new debug mode of the component.
