Detailed Description

A lightweight identifier that may be used to identify a particular cached stage within a UsdStageCache.

An identifier may be converted to and from long int and string, to facilitate use within restricted contexts.

Id objects are only valid with the stage from which they were obtained. It never makes sense to use an Id with a stage other than the one it was obtained from.

Create an Id from a string value.

The supplied val must have been obtained by calling ToString() previously.
