<p>
Notifies if this object has been fully processed in the chain.
<p>
This notifies the caller if the chain has been fully processed. This is useful so that the base classes can modify the chain if it needs to after it has been changed or modified and before any data it passed thru the chain. This is needed for things such as the sample rate converter class that can be inserted automattically if needed. If TRUE is returned then this node has not changed since it was processed last. If FALSE then this node has changed.     </td>

Replaces a parent with another parent keeping the same ID.

This allows one to replace one parent with another parent while keeping the same ID.

Sets the processed state for this object in the chain.
<p>
This allows the caller to set the state of the node. The state is set in proper node class. It is initially set to FALSE in the node class. The caller should set it to TRUE when the chain has been fully setup and processed. Each node in the chain must be processed before data can be puled thru the chain.     </td>
