Detailed Description

Utility class that wraps a node whose state is locked. Having this is a separate class is useful because it allows methods to communicate that they expect the node to be locked.

Member Data Documentation

◆ delayed_required_outputs

Vector<const OutputSocket *> blender::fn::lazy_function::LockedNode::delayed_required_outputs

Used to delay notifying (and therefore locking) other nodes until the current node is not locked anymore. This might not be strictly necessary to avoid deadlocks in the current code, but is a good measure to avoid accidentally adding a deadlock later on. By not locking more than one node per thread at a time, deadlocks are avoided.

The notifications will be send right after the node is not locked anymore.
