class IDRegistry::RegistryMiddleware::ClearRegistry

A registry task that clears a registry at the end of a request.

You may also provide an optional condition block, which is called and passed the Rack env to determine whether the registry should be cleared. If no condition block is provided, the registry is always cleared.

Public Class Methods
