Constructor Detail

BoundsAlignment

protected BoundsAlignment(StrictBounds bounds)

Creates a new alignment object.

Parameters:

bounds - the reference bounds (alignment will be performed relative to this rectangle).

Method Detail

getReferenceBounds

protected StrictBounds getReferenceBounds()

Returns the internal reference bounds. This is no clone or copy, so take care!

Returns:

the reference bounds.

align

public abstract StrictBounds align(StrictBounds r)

Aligns a rectangle with this object's reference bounds.

Subclasses determine the exact alignment behaviour (for example, the TopAlignment class will align a rectangle to the top of the reference bounds).

Parameters:

r - the rectangle to be aligned with this object's reference bounds.

Returns:

the aligned rectangle.
