Class TaskGraphCheckerImp

java.lang.Object

org.trianacode.taskgraph.imp.TaskGraphCheckerImp

All Implemented Interfaces:

TaskGraphListener, TaskListener, TaskGraphChecker

public class TaskGraphCheckerImp
extends java.lang.Object
implements TaskGraphChecker

A class responsible for maintaining the consitency of taskgraphs with regards to the input/output nodes on their control tasks. For example, if a group input node is deleted, then the corresponding loop out node on the control task is also deleted.

Method Detail

monitorTaskGraph

public void monitorTaskGraph(TaskGraph taskgraph)

Sets this taskgraph checker to monitor the specified taskgraph, and any sub-taskgraphs

Specified by:

monitorTaskGraph in interface TaskGraphChecker

unmonitorTaskGraph

public void unmonitorTaskGraph(TaskGraph taskgraph)

Removes this taskgraph checker from monitoring the specified taskgraph, and any sub-taskgraphs

Specified by:

unmonitorTaskGraph in interface TaskGraphChecker

taskCreated

public void taskCreated(TaskGraphTaskEvent event)

Called when a new task is created in a taskgraph.

Specified by:

taskCreated in interface TaskGraphListener

taskRemoved

public void taskRemoved(TaskGraphTaskEvent event)

Called when a task is removed from a taskgraph. Note that this method is called when tasks are removed from a taskgraph due to being grouped (they are place in the group's taskgraph).

Specified by:

taskRemoved in interface TaskGraphListener

cableConnected

public void cableConnected(TaskGraphCableEvent event)

Called when a new connection is made between two tasks.

Specified by:

cableConnected in interface TaskGraphListener

cableReconnected

public void cableReconnected(TaskGraphCableEvent event)

Called when a connection is reconnected to a different task.

Specified by:

cableReconnected in interface TaskGraphListener

cableDisconnected

public void cableDisconnected(TaskGraphCableEvent event)

Called before a connection between two tasks is removed.

Specified by:

cableDisconnected in interface TaskGraphListener

controlTaskStateChanged

public void controlTaskStateChanged(ControlTaskStateEvent event)

Called when the control task is connected/disconnected or unstable

Specified by:

controlTaskStateChanged in interface TaskGraphListener

nodeDisconnected

public void nodeDisconnected(Node node)

Called before a node is diconnected from a cable.

taskPropertyUpdate

public void taskPropertyUpdate(TaskPropertyEvent event)

Called when the core properties of a task change i.e. its name, whether it is running continuously etc.

Specified by:

taskPropertyUpdate in interface TaskListener

parameterUpdated

public void parameterUpdated(ParameterUpdateEvent event)

Called when the value of a parameter is changed, including when a parameter is removed.

Specified by:

parameterUpdated in interface TaskListener

nodeAdded

public void nodeAdded(TaskNodeEvent event)

Called when a data input node is added.

Specified by:

nodeAdded in interface TaskListener

nodeRemoved

public void nodeRemoved(TaskNodeEvent event)

If the node being removed is a group nodes the this removes the corresponding loop node on the control task

Specified by:

nodeRemoved in interface TaskListener

taskDisposed

public void taskDisposed(TaskDisposedEvent event)

Called before the task is disposed

Specified by:

taskDisposed in interface TaskListener
