Module Externs

Provides classes for working with external declarations from Closure-style externs files.

A declaration may either declare a type alias, a global variable or a member variable. Member variables may either be static variables, meaning that they are directly attached to a global object (typically a constructor function), or instance variables, meaning that they are attached to the ‘prototype’ property of a constructor function.

An example of a type alias declaration is

 /** @typedef {String} */
 var MyString;
 

Examples of a global variable declarations are

 var Math = {};
 function Object() {}
 var Array = function() {};
 

Examples of static member variable declarations are

 Math.PI;
 Object.keys = function(obj) {};
 Array.isArray = function(arr) {};
 

Examples of instance member variable declarations are

 Object.prototype.hasOwnProperty = function(p) {};
 Array.prototype.length;
