Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Represents a disconnected resource.

When we use #disconnect for MemoryAdapter and </tt>FileSystemAdapter</tt>, we want to free underlying resources such as a mutex or a file descriptor.

These adapters use to use anonymous descriptors that are destroyed by Ruby VM after each operation. Sometimes we need to clean the state and start fresh (eg. during a test suite or a deploy).

Instead of assign nil to these instance variables, we assign this special type: DisconnectedResource.

In case an operation is still performed after the adapter was disconnected, instead of see a generic NoMethodError for nil, a developer will face a specific message relative to the state of the adapter.
