Method Detail

getPoint

public Point2D getPoint()

Description copied from interface: Handler

Generic method of getting the 2D point that represents a handler of a geometry.

Each handler of each geometry adapts this method to its own behavior in that geometry, that implies that could not be implemented.

Specified by:

getPoint in interface Handler

Returns:

point 2D that represents this handler of geometry

Handler.set(double, double), Handler.move(double, double)

select

public void select(boolean b)

Sets the state of the handler. True if is selected, false if it's not.

Parameters:

b - true if the handler is selected, false otherwise

isSelected()

isSelected

public boolean isSelected()

Returns the state of the handler. True if is selected, false if it's not.

Returns:

true if the handler is selected,false otherwise

select(boolean)

equalsPoint

public boolean equalsPoint(Object obj)

Description copied from interface: Handler

Returns true if the object is a Handler and has the same coordinates as this one.

Specified by:

equalsPoint in interface Handler

Parameters:

obj - the reference object with which to compare

Returns:

true if this object is the same as the obj argument; false otherwise
