C# Class Loyc.LLParserGenerator.LLParserGenerator.GenerateCodeVisitor

Directs code generation using the visitor pattern to visit the predicates in a rule. The process starts with Generate(Rule).

This class is in charge of high-level code generation. It relies on IPGCodeGenHelper for most low-level code generation tasks.

Inheritance: Loyc.LLParserGenerator.PredVisitor
