Graph::Predecessor

Defined in: TSGraph.h

Returns a boolean value indicating whether one element precedes another.

Prototype

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

Parameters

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

Description

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