geos::operation::buffer Namespace Reference

Provides classes for computing buffers of geometries. More...

Classes
class	BufferBuilder
	Builds the buffer geometry for a given input geometry and precision model. More...
class	BufferCurveSetBuilder
	Creates all the raw offset curves for a buffer of a Geometry. More...
class	BufferInputLineSimplifier
	Simplifies a buffer input line to remove concavities with shallow depth. More...
class	BufferNodeFactory
	Creates nodes for use in the geomgraph::PlanarGraph constructed during buffer operations. NOTE: also used by operation::valid. More...
class	BufferOp
	Computes the buffer of a geometry, for both positive and negative buffer distances. More...
class	BufferParameters
	Contains the parameters which describe how a buffer should be constructed. More...
class	BufferSubgraph
	A connected subset of the graph of DirectedEdge and geomgraph::Node. More...
class	MaximalEdgeRing
	A ring of DirectedEdges which may contain nodes of degree > 2. More...
class	MinimalEdgeRing
	A ring of Edges with the property that no node has degree greater than 2. More...
class	OffsetCurve
class	OffsetCurveBuilder
	Computes the raw offset curve for a single Geometry component (ring, line or point). More...
class	OffsetCurveSection
class	OffsetSegmentGenerator
class	OffsetSegmentString
class	PolygonBuilder
	Forms Polygon out of a graph of geomgraph::DirectedEdge. More...
class	RightmostEdgeFinder
	A RightmostEdgeFinder find the geomgraph::DirectedEdge in a list which has the highest coordinate, and which is oriented L to R at that point. (I.e. the right side is on the RHS of the edge.) More...
class	SubgraphDepthLocater
	Locates a subgraph inside a set of subgraphs, in order to determine the outside depth of the subgraph. More...
