schemaManager.js:

(C) 2009 Rackspace Hosting, All Rights Reserved
|
|
|
|
This file defines a single object in global scope:
|
|
|
|
trc.schema.sampleManager
|
|
|
|
The object is responsible for loading, formatting, and displaying
|
|
samples in schema files. It expects trc.util to be defined which is
|
|
provided in trc/util.js.
|
|
|
|
Code highlighting is provided by SHJS
|
|
(http://shjs.sourceforge.net/). It should also be loaded before
|
|
this code is initialized.
|
|
|
|
All methods/properties prepended with an underscore (_) are meant
|
|
for internal use.
