CoordinateSequencecreate (std::vector< Coordinate > *coords) const
 Returns a CoordinateArraySequence based on the given vector (the vector is not copied - callers give up ownership).
CoordinateSequencecreate (std::vector< Coordinate > *coords, std::size_t dims) const
 Returns a CoordinateSequence based on the given array.

 Returns the singleton instance of CoordinateArraySequenceFactory.

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 
) const
virtual

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.

@param coordinates the coordinates
Parameters
dimension0, 2 or 3 with 0 indicating unknown at this time.
