Constructor Detail

NewChangeStrategy

public NewChangeStrategy(boolean ratioFixed,
                         double ratio,
                         Rectangle2D bounds)

Creates a change strategy which creates a new rectangle. It respects the specified ratio if ratioFixed is true.

Parameters:

ratioFixed - indicates whether the ratio will be fixed

ratio - defines the fixed ratio

bounds - the bounds within which the new rectangle must be contained

Method Detail

beforeBeginHook

protected void beforeBeginHook(Point2D point)

Called before the change begins at the specified point.

Parameters:

point - a point

getFixedCorner

protected Point2D getFixedCorner()

Returns the corner which is fixed during the change. Called once when the change begins.

Returns:

the corner which is fixed during the change

doBegin

protected final Rectangle2D doBegin(Point2D point)

Begins the change at the specified point.

Parameters:

point - a point

Returns:

the new rectangle

doContinue

protected Rectangle2D doContinue(Point2D point)

Continues the change to the specified point. Must not be called before a call to Rectangle2DChangeStrategy.beginChange(javafx.geometry.Point2D).

Parameters:

point - a point

Returns:

the new rectangle

doEnd

protected final Rectangle2D doEnd(Point2D point)

Ends the change at the specified point. Must not be called before a call to Rectangle2DChangeStrategy.beginChange(javafx.geometry.Point2D).

Parameters:

point - a point

Returns:

the new rectangle

isRatioFixed

protected final boolean isRatioFixed()

Indicates whether the ratio is fixed. If so, the ratio can be accessed with getRatio().

Returns:

true if the ratio is fixed; false otherwise

getRatio

protected final double getRatio()

The current ratio. Can only be called without exception when isRatioFixed() returns true.

Returns:

the current ratio

beginChange

public final Rectangle2D beginChange(Point2D point)

Begins the change at the specified point.

Specified by:

beginChange in interface Rectangle2DChangeStrategy

Parameters:

point - a point

Returns:

the new rectangle

continueChange

public final Rectangle2D continueChange(Point2D point)

Continues the change to the specified point. Must not be called before a call to Rectangle2DChangeStrategy.beginChange(javafx.geometry.Point2D).

Specified by:

continueChange in interface Rectangle2DChangeStrategy

Parameters:

point - a point

Returns:

the new rectangle

endChange

public final Rectangle2D endChange(Point2D point)

Ends the change at the specified point. Must not be called before a call to Rectangle2DChangeStrategy.beginChange(javafx.geometry.Point2D).

Specified by:

endChange in interface Rectangle2DChangeStrategy

Parameters:

point - a point

Returns:

the new rectangle

afterEndHook

protected void afterEndHook(Point2D point)

Called after the change ends at the specified point.

Parameters:

point - a point
