replaceTypeVariables

public Type replaceTypeVariables(TypeParameterDeclaration tpToReplace,

Description copied from interface: Type

Replace all variables referring to the given TypeParameter with the given value. By replacing these values I could also infer some type equivalence. Those would be collected in the given map.
