Class GroupLayout.Spring

abstract class GroupLayout.Spring extends Object

Spring consists of a range: min, pref and max a value some where in the middle of that and a location. Subclasses must override methods to get the min/max/pref and will likely want to override the setSize method. Spring automatically caches the min/max/pref. If the min/pref/max has internally changes, or needs to be updated you must invoked clear.
