void GEOM_FADE2D::ConstraintSegment2::addOwner ( ConstraintGraph2 pOwner)

Sets a specific ConstraintGraph2 as owner of the current ConstraintSegment2. internal use.

ConstraintInsertionStrategy GEOM_FADE2D::ConstraintSegment2::getCIS ( ) const
the constraint insertion strategy (CIS)
Point2* GEOM_FADE2D::ConstraintSegment2::getSrc ( ) const
the source point
Point2* GEOM_FADE2D::ConstraintSegment2::getTrg ( ) const
the source point
Point2* GEOM_FADE2D::ConstraintSegment2::insertAndSplit ( const Point2 splitPoint)

Splits the ConstraintSegment2 (which must be alive) at splitPoint.

It may be impossible to represent a point on a certain line segment using floatingpoint arithmetic. Therefore it is highly recommended to split a ConstraintSegment2 object not just be inserting points into the triangulation but using the present method. It does not require that splitPoint is exactly on the segment.

A splitted ConstraintSegment2 is dead and it has two child segments (which may also be dead and have children). The class is organized as a binary tree.
bool GEOM_FADE2D::ConstraintSegment2::isAlive ( ) const
if the object is alive
void GEOM_FADE2D::ConstraintSegment2::kill ( )

void GEOM_FADE2D::ConstraintSegment2::setAdjacentArea ( double  adjacentArea_)
Only use if you know what you are doing.
bool GEOM_FADE2D::ConstraintSegment2::split_combinatorialOnly ( Point2 pSplit)

internal use only unless you do something very unusual

bool GEOM_FADE2D::ConstraintSegment2::splitAndRemovePrev ( const Point2 split)

internal use. Deprecated!

void GEOM_FADE2D::ConstraintSegment2::unkill ( )
