ClosestNode()

oofem::ClosestNode::ClosestNode ( const FloatArray & pos, Domain * d )

inline

Constructor

Parameters

pos	Starting position of the search
d	Domain containing nodes

References domain, initFlag, and startingPosition.

Member Function Documentation

evaluate()

bool oofem::ClosestNode::evaluate ( int & nodeNr )

inlineoverridevirtual

Evaluates a node. The closest nodes are stored in a container, if their distance to starting position is the same. Is the distance smaller than previous one, the container is emptied and new node is added.

Parameters

nodeNr

Number of the node in the domain list

Returns

true after evaluation is processed.

Implements oofem::SL_Evaluation_Functor< int >.

giveResult()

void oofem::ClosestNode::giveResult ( std ::list< int > & answer )

inlineoverridevirtual

Gives the closest nodes

Parameters

answer

List containing numbers of the closest nodes

Implements oofem::SL_Evaluation_Functor< int >.

Definition at line 228 of file octreelocalizertutil.h.

References closestNodeIndices.

giveStartingPosition()

void oofem::ClosestNode::giveStartingPosition ( FloatArray & position )

inlineoverridevirtual

Gives the starting position of the search

Parameters

position

startingPosition

Implements oofem::SL_Evaluation_Functor< int >.

References startingPosition.

isBBXStage1Defined()

bool oofem::ClosestNode::isBBXStage1Defined ( BoundingBox & BBXStage1 )

inlineoverridevirtual

Stage1 means, we are looking for objects in a distance given by some boundingBox (e.g. IPs around some given coordinates)

Implements oofem::SL_Evaluation_Functor< int >.

Definition at line 232 of file octreelocalizertutil.h.

isBBXStage2Defined()

bool oofem::ClosestNode::isBBXStage2Defined ( BoundingBox & BBXStage2 )

inlineoverridevirtual

Stage2BBX is given by results of a prior search. e.g. We found a closest point to another point in an octant, BBX is defined by the distance from each other and the found closest point. Now we have to check surrounding octants whithin this bounding, which may contain points closer to starting point.
