Class SymTypeFreeVariableReplaceVisitor

java.lang.Object

de.monticore.types3.util.SymTypeDeepCloneVisitor

de.monticore.types3.generics.util.SymTypeFreeVariableReplaceVisitor

All Implemented Interfaces:

ISymTypeVisitor

public class SymTypeFreeVariableReplaceVisitor
extends SymTypeDeepCloneVisitor

Replaces type variables, that are free in the given enclosing scope, with inference variables. Returns both, the new type, and a map from the replaced variables to the replacement. Usage: calculate(symType, enclosingScope)
