Detailed Description

Represents a branch/node of a shock graph.

Todo:

At this moment, the type of a branch is not 1..4 but instead the set of numbers that the shock graph detection algorithm returns. SHOCK_base=100, SHOCK_2or3=100, SHOCK_1=101, SHOCK_2=102, SHOCK_3=103, SHOCK_4=104, ROOT=105 (values defined in Shock.h).

Member Function Documentation

void SGNode::ComputeDerivedValues (    )  [virtual]

Computes the node's TSV norm considering that the TSV includes the eigenvalue of the node too. Reimplemented from DAGNode. Definition at line 160 of file SGNode.cpp. References DAGNode::ComputeDerivedValues(), and m_shocks. Referenced by ShockGraph::GroupShockPoints(), and ShockGraph::Insert4sAnd2s().

DAGNode * SGNode::CreateObject (    )  const [virtual]

Creates a new SGNode with a copy of the information conatines in 'this'. This functions is required by SmartPtr<DAGNode*>::operator[]. Implements DAGNode. Definition at line 93 of file SGNode.cpp. References SGNode().

int SGNode::GetShapeForGraph (    )  const [virtual]

Returns the shape for the node in the graph. See graphwin.h line #160 for the 'enum' node shape options. Reimplemented from DAGNode. Definition at line 265 of file SGNode.cpp.
