use of com.esri.core.geometry.Geometry in project sis by apache.

the class ESRI method tryGetEnvelope.

/**
 * If the given object is an ESRI geometry and its envelope is non-empty, returns
 * that envelope as an Apache SIS implementation. Otherwise returns {@code null}.
 *
 * @param  geometry  the geometry from which to get the envelope, or {@code null}.
 * @return the envelope of the given object, or {@code null} if the object is not
 *         a recognized geometry or its envelope is empty.
