goog.module.AbstractModuleLoader

Loads a list of JavaScript modules.

Pre-fetches a JavaScript module.

Whether or not the implementation supports extra edges.

Optional parameters for the loadModules method.

A map of extra runtime module dependencies. Since the polyfills for the ES6 Map/Set classes would cause a performance regression, we are using plain Javascript objects to mimic their functionality. The outer object will map a moduleId to another object, the keys of which are the moduleIds of the modules it depends on: that is, if map['a']['b'] is true then module 'a' depends on module 'b'.
