- * Marks that this file must be loaded as a module and claims the namespace.

|
|
|
- *
|
|
|
- * goog.module() has three requirements:
|
|
|
- * - goog.module may not be used in the same file as goog.provide.
|
|
|
- * - goog.module must be the first statement in the file.
|
|
|
- * - only one goog.module is allowed per file.
|
|
|
- *
|
|
|
- * When a goog.module annotated file is loaded, it is enclosed in
|
|
|
- * a strict function closure. This means that:
|
|
|
- * - any variables declared in a goog.module file are private to the file
|
|
|
- * (not global), though the compiler is expected to inline the module.
|
|
|
- * - The code must obey all the rules of "strict" JavaScript.
|
|
|
- * - the file will be marked as "use strict"
|
|
|
- *
|
|
|
- * NOTE: unlike goog.provide, goog.module does not declare any symbols by
|
|
|
- * itself. If declared symbols are desired, use
|
|
