Class MoveSnapContext.MovingInfo

java.lang.Object
  y.view.MoveSnapContext.MovingInfo

Direct Known Subclasses:

MoveSnapContext.MovingBendInfo, MoveSnapContext.MovingPortInfo

Enclosing class:

MoveSnapContext

public abstract static class MoveSnapContext.MovingInfo
extends java.lang.Object

The abstract base class of the classes that describe items that will be moved in the context of the move operation that is described by the MoveSnapContext. There are specialized subclasses for both bends and ports.

Constructor Summary

protected

MoveSnapContext.MovingInfo(YPoint originalLocation, byte mode) Creates a new instance using the provided original location and the movement mode.

Method Summary

abstract void	applyLocation(double dx, double dy) Moves the item described by this item according to the delta coordinates.
YPoint	getOriginalLocation() Yields the location of the item before the move operation was initiated.
boolean	isFreelyMovable() Tests whether the item is not constrained to movements along the x or y axis.
boolean	isHorizontallyFixed() Whether the x coordinate of the item is fixed during the move operation.
boolean	isVerticallyFixed() Whether the y coordinate of the item is fixed during the move operation.

Constructor Detail

MoveSnapContext.MovingInfo

protected MoveSnapContext.MovingInfo(YPoint originalLocation,
                                     byte mode)

Creates a new instance using the provided original location and the movement mode.

Parameters:

originalLocation - The location of the item before the movement started.

mode - The constant that describes the movement of the item - one of MoveSnapContext.MOVE_X, MoveSnapContext.MOVE_Y, or MoveSnapContext.MOVE_XY.

Method Detail

getOriginalLocation

public final YPoint getOriginalLocation()

Yields the location of the item before the move operation was initiated.

isFreelyMovable

public final boolean isFreelyMovable()

Tests whether the item is not constrained to movements along the x or y axis.

See Also:

MoveSnapContext.MOVE_XY

isVerticallyFixed

public final boolean isVerticallyFixed()

Whether the y coordinate of the item is fixed during the move operation.

isHorizontallyFixed

public final boolean isHorizontallyFixed()

Whether the x coordinate of the item is fixed during the move operation.

applyLocation

public abstract void applyLocation(double dx,
                                   double dy)

Moves the item described by this item according to the delta coordinates. The delta should be added to the getOriginalLocation()

Parameters:

dx - The delta in x coordinate direction of the move since the movement started.

dy - The delta in y coordinate direction of the move since the movement started.
