Constructor & Destructor Documentation

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

inline

Constructor.

Parameters

pos	Starting position of the search
d	Domain containing nodes

Definition at line 667 of file octreelocalizert.h.

oofem::ClosestNode::~ClosestNode ( )

inline

Destructor.

Definition at line 673 of file octreelocalizert.h.

Member Function Documentation

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

inlinevirtual

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 >.

Definition at line 690 of file octreelocalizert.h.

References oofem::FloatArray::distance(), oofem::Node::giveCoordinates(), and oofem::Domain::giveNode().

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

inlinevirtual

Gives the closest nodes.

Parameters

answer

List containing numbers of the closest nodes

Implements oofem::SL_Evaluation_Functor< int >.

Definition at line 717 of file octreelocalizert.h.

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

inlinevirtual

Gives the starting position of the search.

Parameters

position

startingPosition

Implements oofem::SL_Evaluation_Functor< int >.

Definition at line 679 of file octreelocalizert.h.

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

inlinevirtual

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 721 of file octreelocalizert.h.

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

inlinevirtual

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.
