Example 43 with TypeParameterElement

use of javax.lang.model.element.TypeParameterElement in project auto by google.

the class TypeSimplifier method formalTypeParametersString.

// The formal type parameters of the given type.
// If we have @AutoValue abstract class Foo<T extends SomeClass> then this method will
// return <T extends Something> for Foo. Likewise it will return the angle-bracket part of:
// Foo<SomeClass>
// Foo<T extends Number>
// Foo<E extends Enum<E>>
// Foo<K, V extends Comparable<? extends K>>
// Type variables need special treatment because we only want to include their bounds when they
// are declared, not when they are referenced. We don't want to include the bounds of the second E
// in <E extends Enum<E>> or of the second K in <K, V extends Comparable<? extends K>>. That's
// why we put the "extends" handling here and not in ToStringTypeVisitor.
