Constructor Detail

MoveChangeStrategy

public MoveChangeStrategy(Rectangle2D previous,
                          Rectangle2D bounds)

Creates a new change strategy which moves the specified rectangle within the specified bounds.

Parameters:

previous - the previous rectangle this move is based on

bounds - the bounds within which the rectangle can be moved

MoveChangeStrategy

public MoveChangeStrategy(Rectangle2D previous,
                          double maxX,
                          double maxY)

Creates a new change strategy which moves the specified rectangle within the specified bounds defined by the rectangle from (0, 0) to (maxX, maxY).

Parameters:

previous - the previous rectangle this move is based on

maxX - the maximal x-coordinate of the right edge of the created rectangles; must be greater than or equal to the previous rectangle's width

maxY - the maximal y-coordinate of the lower edge of the created rectangles; must be greater than or equal to the previous rectangle's height

Method Detail

doBegin

protected 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 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

getPrevious

protected final Rectangle2D getPrevious()

The previous rectangle this change is based on.

Returns:

the previous 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

beforeBeginHook

protected void beforeBeginHook(Point2D point)

Called before the change begins at the specified point.

Parameters:

point - a point

afterEndHook

protected void afterEndHook(Point2D point)

Called after the change ends at the specified point.

Parameters:

point - a point
