Graph::Predecessor

Defined in: C4Graph.h

Returns a boolean value indicating whether one node precedes another.

Prototype

bool Predecessor(const GraphNodeBase *first, const GraphNodeBase *second);

Parameters

`first`	The first node in the graph.
`second`	The second node in the graph.

Description

The Predecessor function returns true if the node specified by the first parameter precedes the node specified by the second parameter in a graph, and it returns false otherwise. In order for the first node to precede the second, there must be a sequence of edges starting at the first node that can be followed through a sequence of nodes that ultimately finishes at the second node.
