Example 94 with LinearRing

use of com.revolsys.geometry.model.LinearRing in project com.revolsys.open by revolsys.

the class EdgeRing method findEdgeRingContaining.

/**
 * Find the innermost enclosing shell EdgeRing containing the argument EdgeRing, if any.
 * The innermost enclosing ring is the <i>smallest</i> enclosing ring.
 * The algorithm used depends on the fact that:
 * <br>
 *  ring A contains ring B iff envelope(ring A) contains envelope(ring B)
 * <br>
 * This routine is only safe to use if the chosen point of the hole
 * is known to be properly contained in a shell
 * (which is guaranteed to be the case if the hole does not touch its shell)
 *
 * @return containing EdgeRing, if there is one
 * or null if no containing EdgeRing is found
