public void recycle()

Description copied from interface: Resource

Cleans up and recycles internal resources.

It is only safe to call this method if there are no current resource consumers and if this method has not yet been called. Typically this occurs at one of two times:

• During a resource load when the resource is transformed or transcoded before any consumer have ever had access to this resource
• After all consumers have released this resource and it has been evicted from the cache

For most users of this class, the only time this method should ever be called is during transformations or transcoders, the framework will call this method when all consumers have released this resource and it has been evicted from the cache.
