Constructor Detail

OperatorIntersectionCursor

OperatorIntersectionCursor(GeometryCursor inputGeoms,
                           GeometryCursor geomIntersector,
                           SpatialReference sr,

Method Detail

next

public Geometry next()

Description copied from class: GeometryCursor

Moves the cursor to the next Geometry. Returns null when reached the end. The behavior of the cursor is undefined after the method returns null.

Specified by:

next in class GeometryCursor

getGeometryID

public int getGeometryID()

Description copied from class: GeometryCursor

Returns the ID of the current geometry. The ID is propagated across the operations (when possible). Returns an ID associated with the current Geometry. The ID is passed along and is returned by some operators to preserve relationship between the input and output geometry classes. It is not always possible to preserve an ID during an operation.

Specified by:

getGeometryID in class GeometryCursor

intersect

Geometry intersect(Geometry input_geom)

prepareVector_

GeometryCursor prepareVector_(VertexDescription descr,
                              int dimensionMask,
