Class IlvAbstractConstraint

java.lang.Object

ilog.views.gantt.model.IlvAbstractConstraint

All Implemented Interfaces:

IlvConstraint, Serializable

Direct Known Subclasses:

IlvSimpleConstraint, IlvTableConstraint

public abstract class IlvAbstractConstraint
extends Object
implements IlvConstraint, Serializable

IlvAbstractConstraint is the superclass of all IlvConstraint implementations. It provides a basic framework of event and property support which can be used by all concrete subclasses. All constraint events are routed to the Gantt data model where interested listeners can register. Constraints do not handle listener subscription and notification directly. Subclasses should always use the fireEvent(ilog.views.gantt.event.ConstraintEvent) method to fire ConstraintEvent events so that generated events will be routed properly.

Since:

JViews 5.5

Constructor Detail

IlvAbstractConstraint

public IlvAbstractConstraint()

Creates a new IlvAbstractConstraint.

Method Detail

getGanttModel

protected IlvGanttModel getGanttModel()

Returns the data model that is managing this constraint. This will be null if this constraint has not been added to a data model yet.

Returns:

The Gantt data model managing the constraint.

setGanttModelImpl

public void setGanttModelImpl(IlvGanttModel model)

This method is invoked by IlvGanttModel when the constraint is added or removed.

Warning: This method is considered to be part of an IlvConstraint's internal implementation and is not a public API. You should only invoke this method directly if you have created your own IlvGanttModel implementation.

Specified by:

setGanttModelImpl in interface IlvConstraint

Parameters:

model - The data model that this constraint has been added to, or null if this constraint has been removed from the data model.

fireEvent

protected final void fireEvent(ConstraintEvent event)

Fires an event from this constraint. Subclasses should always use this method to fire constraint events because it properly routes the event.

Parameters:

event - The constraint event.

fireTypeAboutToChange

protected ConstraintTypeEvent fireTypeAboutToChange(IlvConstraintType newType)

Fires a typeAboutToChange event and returns the event after dispatching it to all listeners.

Parameters:

newType - The new type proposed for the constraint.

Returns:

The event after dispatching to all listeners.

ConstraintTypeEvent

fireTypeChanged

protected void fireTypeChanged(IlvConstraintType oldType)

Fires a typeChanged event.

Parameters:

oldType - The previous type of the constraint.

ConstraintTypeEvent

paramString

protected String paramString()

Returns a parameter string that represents the state of this constraint.

Returns:

A string representing the status of the constraint.

toString

public String toString()

Returns a string representation of this constraint.

Overrides:

toString in class Object

Returns:

A string representing the constraint.
