Class TypeResolver.TypeVariableKey

  • Enclosing class:
    TypeResolver
    static final class TypeResolver.TypeVariableKey
extends java.lang.Object
    Wraps around TypeVariable<?> to ensure that any two type variables are equal as long as they are declared by the same GenericDeclaration and have the same name, even if their bounds differ.

    While resolving a type variable from a var -> type map, we don't care whether the type variable's bound has been partially resolved. As long as the type variable "identity" matches.

    On the other hand, if for example we are resolving List<A extends B> to List<A extends String>, we need to compare that <A extends B> is unequal to <A extends String> in order to decide to use the transformed type instead of the original type.
