Method Detail

substitute

public TypeBinding substitute(Substitution substitution,
                              TypeBinding originalType)

Override method Scope.Substitutor.substitute(Substitution, TypeBinding), to add substitution of types other than type variables.

Overrides:

substitute in class Scope.Substitutor

getP

protected TypeBinding getP(int i)

Get the type corresponding to the ith inference variable. Default behavior is to answer the inference variable's type parameter. Sub-class may override to substitute other types.
