Usage

From source file:org.kalypsodeegree_impl.model.geometry.GM_Envelope_Impl.java

/**
 * returns a new GM_Envelope object representing the intersection of this GM_Envelope with the specified GM_Envelope.
 * * Note: If there is no intersection at all GM_Envelope will be null.
 * //from ww  w .  ja va 2 s  .  com
 * @param bb

 * @return the largest GM_Envelope contained in both the specified GM_Envelope and in this GM_Envelope.
