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...

## Functions
