NstDependence

class NstDependence : public NstEdge

Dependence between two array references.

Inheritance:

Public Fields
int depth: Number of common loops that surround both array references.
NstDirectionVector* dir_vector: Approximation of distance vectors by a direction vector.
int level: Approximation of distance vectors by a dependence level.
NstPolyhedron* poly: Approximation of distance vectors by a polyhedron.

Public Methods
NstEdge* clone(int deep = 0): Clones the dependence.
unsigned long from_tag(): Returns the tag of dependence source.
unsigned long to_tag(): Returns the tag of dependence sink.
Nst_Edge_Type type(): Returns the type of edge: here NST_DEPENDENCE.
NstDependenceType typedep(): Returns the type of dependence, such as flow, anti, output, etc

Inherited from NstEdge:

Public Fields
