Detailed Description

A factory to create concrete instances of CoordinateSequences.

Used to configure GeometryFactorys to provide specific kinds of CoordinateSequences.

Member Function Documentation

create() [1/5]

virtual std::unique_ptr< CoordinateSequence > geos::geom::CoordinateSequenceFactory::create ( ) const

pure virtual

Returns an empty CoordinateSequence, the dimensions will be autodetected when it is populated.

Implemented in geos::geom::CoordinateArraySequenceFactory.

create() [2/5]

virtual std::unique_ptr< CoordinateSequence > geos::geom::CoordinateSequenceFactory::create ( const CoordinateSequence &  coordSeq ) const

pure virtual

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

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

Parameters

coordSeq

the coordinate sequence to copy

Implemented in geos::geom::CoordinateArraySequenceFactory.

create() [3/5]

virtual std::unique_ptr< CoordinateSequence > geos::geom::CoordinateSequenceFactory::create ( std::size_t  size, std::size_t  dimension = 0  ) const

pure virtual

Creates a CoordinateSequence of the specified size and dimension.

For this to be useful, the CoordinateSequence implementation must be mutable.

Parameters

size	the number of coordinates in the sequence
dimension	the dimension of the coordinates in the sequence (0=unknown, 2, or 3 - ignored if not user specifiable)

Implemented in geos::geom::CoordinateArraySequenceFactory.

create() [4/5]

virtual std::unique_ptr< CoordinateSequence > geos::geom::CoordinateSequenceFactory::create ( std::vector< Coordinate > &&  coordinates, std::size_t  dimension = 0  ) const

pure virtual

Returns a CoordinateSequence based on the given array.

Parameters

coordinates	the coordinates
dimension	0, 2 or 3 with 0 indicating unknown at this time.

create() [5/5]

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

pure 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.

Parameters

coordinates	the coordinates
dimension	0, 2 or 3 with 0 indicating unknown at this time.
