Class JSTypeExpression

  • All Implemented Interfaces:
    java.io.Serializable
    public final class JSTypeExpression
extends java.lang.Object
implements java.io.Serializable
    When parsing a jsdoc, a type-annotation string is parsed to a type AST. Somewhat confusingly, we use the Node class both for type ASTs and for the source-code AST. JSTypeExpression wraps a type AST. During type checking, type ASTs are evaluated to JavaScript types.
