TreeVisitor<Node,Void>

Enclosing class:

CFCFGBuilder

protected static class CFCFGBuilder.CFCFGTranslationPhaseOne
extends CFGTranslationPhaseOne

A specialized phase-one CFG builder, with a few modifications that make use of the type factory. It is responsible for: 1) translating foreach loops so that the declarations of their iteration variables have the right annotations, 2) registering the containing elements of artificial trees with the relevant type factories, and 3) generating appropriate assertion CFG structure in the presence of @AssumeAssertion assertion strings which mention the checker or its supercheckers.
