Detailed Description

An interface for classes which represent a sequence of contiguous line segments.

SegmentStrings can carry a context object, which is useful for preserving topological or parentage information.

Constructor & Destructor Documentation

SegmentString()

geos::noding::SegmentString::SegmentString ( const void * newContext )

inline

Construct a SegmentString.

Parameters

newContext

the context associated to this SegmentString

Referenced by geos::noding::BasicSegmentString::BasicSegmentString(), and getCoordinates().

Member Function Documentation

getCoordinate()

virtual const geom::Coordinate & geos::noding::SegmentString::getCoordinate ( unsigned int i ) const

pure virtual

Implemented in geos::noding::BasicSegmentString.

getCoordinates()

virtual geom::CoordinateSequence * geos::noding::SegmentString::getCoordinates ( ) const

pure virtual

Return a pointer to the CoordinateSequence associated with this SegmentString.

Note that the CoordinateSequence is owned by this SegmentString!

Implemented in geos::noding::BasicSegmentString, and geos::noding::NodedSegmentString.

References SegmentString().

getData()

const void * geos::noding::SegmentString::getData ( ) const

inline

Gets the user-defined data for this segment string.

Returns

the user-defined data

isClosed()

virtual bool geos::noding::SegmentString::isClosed ( ) const

pure virtual

Implemented in geos::noding::BasicSegmentString.

print()

virtual std::ostream & geos::noding::SegmentString::print ( std::ostream & os ) const

virtual

Reimplemented in geos::noding::BasicSegmentString.

setData()

void geos::noding::SegmentString::setData ( const void * data )

inline

Sets the user-defined data for this segment string.

Parameters

data	an Object containing user-defined data

size()

virtual unsigned int geos::noding::SegmentString::size ( ) const

pure virtual

Implemented in geos::noding::BasicSegmentString.
