                       Rectangle target)

Description copied from interface: BoundaryRestriction

Calculates the bounds which window can have.

Specified by:

check in interface BoundaryRestriction

Parameters:

window - the window whose future bounds should be checked.

target - the bounds window should have, this method should not write into target.
