Detailed Description
Implementation of UnionStrategy that provides overlay using the first generation overlay routines.
Member Function Documentation
◆ isFloatingPrecision()
|
overridevirtual |
Indicates whether the union function operates using a floating (full) precision model. If this is the case, then the unary union code can make use of the OverlapUnion performance optimization, and perhaps other optimizations as well. Otherwise, the union result extent may not be the same as the extent of the inputs, which prevents using some optimizations.
Implements geos::operation::geounion::UnionStrategy.
◆ Union()
|
overridevirtual |
Computes the union of two geometries. This method may throw a util::TopologyException if one is encountered
Implements geos::operation::geounion::UnionStrategy.
