BddSystem

The bdd system.

BddNode

The bdd node to treat.

BddAssoc

The variable association.

existbddnodeassocon suppress in BddNode, all the variables associated with something in the variable association BddAssoc, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.

existbddnodeassocon returns the computed bdd node.
