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

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

Construct a SegmentString.

Parameters
newContextthe context associated to this SegmentString

Member Function Documentation

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

Return a pointer to the CoordinateSequence associated with this SegmentString.

Note
The CoordinateSequence is owned by this SegmentString!

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

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

Gets the user-defined data for this segment string.

Returns
the user-defined data
void geos::noding::SegmentString::setData ( const void *  data)
inline

Sets the user-defined data for this segment string.

Parameters
dataan Object containing user-defined data
