Detailed Description

Creates CoordinateSequences internally represented as an array of Coordinates.

Member Function Documentation

CoordinateSequence* geos::geom::CoordinateArraySequenceFactory::create ( std::vector< Coordinate > *  coordinates,
std::size_t  dimension = 0 
) const
overridevirtual

Returns a CoordinateSequence based on the given array.

Whether the array is copied or simply referenced is implementation-dependent. For this reason caller does give up ownership of it. Implementations that will not copy it will need take care of deleting it.

This method must handle null arguments by creating an empty sequence.

Parameters
coordinatesthe coordinates
dimension0, 2 or 3 with 0 indicating unknown at this time.

Implements geos::geom::CoordinateSequenceFactory.

CoordinateSequence* geos::geom::CoordinateArraySequenceFactory::create ( std::size_t  size,
std::size_t  dimension = 0 
) const
overridevirtual

CoordinateSequenceFactory::create(std::size_t, int)

Implements geos::geom::CoordinateSequenceFactory.

CoordinateSequence* geos::geom::CoordinateArraySequenceFactory::create ( const CoordinateSequence coordSeq) const
overridevirtual

Creates a CoordinateSequence which is a copy of the given one.

This method must handle null arguments by creating an empty sequence.

Parameters
coordSeqthe coordinate sequence to copy
