Class ExerciseUpdateEvent

java.lang.Object
  mauda.ExerciseUpdateEvent

public class ExerciseUpdateEvent
extends java.lang.Object
extends java.lang.Object

A semantic event which indicates that a exercise-defined event occured. This high-level event is generated at different places in the whole project, and is normally passed through the queue of JedasPanel, and then transmitted to every ExerciseUpdateListener object, that registered to receive such events using the Exercise's addExerciseUpdateListener method. This event is essential for sychronizing objects with the scheduler (animation).

SPECIAL

public static final int SPECIAL

ID for special events. Further event-specific information is stored in message

OPERATION_EXECUTED

public static final int OPERATION_EXECUTED

ID that indicates that a operation was executed.

See Also:: Constant Field Values

FILENAME_CHANGED

public static final int FILENAME_CHANGED

ID that indicates that the filename of the current exercise was changed.

See Also:: Constant Field Values

CLEAR_PRECEDING

public static final int CLEAR_PRECEDING

ID that indicates that all data-structures should delete their previous stored information related to e.g. already executed operations. For example for OperationRecorder this event will clear all previous stored operations.

CLEAR_FOLLOWING

public static final int CLEAR_FOLLOWING

ID that indicates that all data-structures should delete related to the actual position all following operations.

See Also:: CLEAR_PRECEDING, Constant Field Values

FINISHED_LOADING

public static final int FINISHED_LOADING

ID that indicates that the exercise was finished in loading. Remember that this is normally related to the init-operations of an exercise, what means that a exercise must not have really finished loading, when the this event occures.

See Also:: Constant Field Values

DSOBJECT_HIDE

public static final int DSOBJECT_HIDE

ID that indicates to hide the animation-object

See Also:: Constant Field Values

DSOBJECT_SHOW

public static final int DSOBJECT_SHOW

ID that indicates to show a previously hidden animation- object.

See Also:: Constant Field Values

BACK

public static final int BACK

ID that indicates that an undo was made

See Also:: Constant Field Values

FORWARD

public static final int FORWARD

ID that indicates that a redo was made

See Also:: Constant Field Values

FORWARD_ANIMATED

public static final int FORWARD_ANIMATED

ID that indicates that a animated redo was made. This event is only fired, when AnimatedUndoRedo was used.

See Also:: AnimatedUndoRedo, Constant Field Values

RESET

public static final int RESET

ID that indicates that the exercise was cleared. That means e.g. for OperationRecorder to delete all stored operations.

See Also:: Constant Field Values

PLUGIN_CHANGED

public static final int PLUGIN_CHANGED

ID that indicates that the plug in was changed.

See Also:: Constant Field Values

JUMP

public static final int JUMP

ID that indicates that the user is jumped to another operation. The delta-value can accessed by getValue()

ID that indicates that all operations in the current queue are fully executed by the JedasPanel.

See Also:: Constant Field Values

ID that indicates that the JedasPanel starts the execution of passed operations/events to the queue.

See Also:: Constant Field Values

SUSPEND_EXECUTION

ID that indicates that the Jedas-Animation goes in suspend-Mode. This is used, when e.g. the recording is paused.

See Also:: Constant Field Values

RESUME_EXECUTION

public static final int RESUME_EXECUTION

ID that indicates that the Jedas-Animation resumes from suspend. This is used, when e.g. a recording was paused, and now continueing.

See Also:: Constant Field Values
