A factory to create concrete instances of CoordinateSequences.
Definition: CoordinateSequenceFactory.h:44
virtual std::unique_ptr< CoordinateSequence > create() const =0
Returns an empty CoordinateSequence, the dimensions will be autodetected when it is populated.
virtual std::unique_ptr< CoordinateSequence > create(std::size_t size, std::size_t dimension=0) const =0
Creates a CoordinateSequence of the specified size and dimension.
virtual std::unique_ptr< CoordinateSequence > create(std::vector< Coordinate > *coordinates, std::size_t dimension=0) const =0
Returns a CoordinateSequence based on the given array.
virtual std::unique_ptr< CoordinateSequence > create(std::vector< Coordinate > &&coordinates, std::size_t dimension=0) const =0
Returns a CoordinateSequence based on the given array.
virtual std::unique_ptr< CoordinateSequence > create(const CoordinateSequence &coordSeq) const =0
Creates a CoordinateSequence which is a copy of the given one.
The internal representation of a list of coordinates inside a Geometry.
