public abstract class SequencerAction

extends PeriodicAction

This class is an abstract class for actions that interact with some kind of Sequencer. The doAction method is left for the subclass to define so that it can define the type of a Sequencer the action deals with. The constraining conditions of the Sequencer are dealt with by this class.

Constructor Detail

SequencerAction

protected SequencerAction(int scale,
                          int period,
                          Sequencer seq)
                   throws QTException

Deprecated. since QTJava 6.1

Create a SequencerAction.

Parameters:

scale - the amount with which a second is divided into at a rate of one

period - the number of scale ticks that elapse between invocations of the action.

seq - the Sequencer.

Method Detail

setConstraint

public void setConstraint(int cons)

Deprecated. since QTJava 6.1

Set the constraining condition that determines the cirumstances of when the attached actionable object is triggered.

Parameters:

cons - the constraint

getConstraint

public int getConstraint()

Deprecated. since QTJava 6.1

Gets the constraining condition of the actionable doAction method

Returns:

the constraint

constraintReached

protected boolean constraintReached()

Deprecated. since QTJava 6.1

Subclasses should return true if after an action is triggered (the doAction method is called) the action has reached one of its specified constraint conditions and the actionable object should be triggered. How this is defined is determined totally by the subclass.

Specified by:

constraintReached in class PeriodicAction

Returns:

true if the actionable object (if set) should be triggered

equals

public boolean equals(java.lang.Object obj)

Deprecated. since QTJava 6.1

Returns true if the objects are equal or false otherwise.

Overrides:

equals in class PeriodicAction

Parameters:

obj - the object to test

Returns:

a boolean
