Class LexicalTypeVariableType

DEPRECATED. Static types from the TypeScript compiler are not longer available. Use one of the following alternatives instead:

Expr.getTypeBinding()
Expr.getNameBinding()
TypeAnnotation.getTypeBinding()

A type that refers to a type variable without a canonical name.

These arise in generic call signatures such as <T>(x: T) => T. The lexical type variable is not associated with a specific call signature, however. The type entity is shared between all such type variables named T.

For example, the following call signatures will appear to have the same return type, as they both return a lexically bound type variable named T:

<T>(x: T) => T
<S, T>(x: S, y: T) => T.
