Detailed Description

Manages the input geometries for an overlay operation. The second geometry is allowed to be null, to support for instance precision reduction.

hasEdges()

bool geos::operation::overlayng::InputGeometry::hasEdges

(

uint8_t

geomIndex

)

const

Tests if an input geometry has edges. This indicates that topology needs to be computed for them.

Parameters

geomIndex

Returns

true if the input geometry has edges

locatePointInArea()

Location geos::operation::overlayng::InputGeometry::locatePointInArea	(	uint8_t	geomIndex,
		const Coordinate &	pt )

Determines the location within an area geometry. This allows disconnected edges to be fully located.

Parameters

geomIndex	the index of the geometry
pt	the coordinate to locate

Returns

the location of the coordinate
