Interface NodeCanFinish

All Known Implementing Classes:

SpringNode, TimingNode

public interface NodeCanFinish

Interface for a ValueNode that has logic that determines when its finished. A node should be considered finished when 1) its inputs are also finished (i.e. won't change) and 2) it won't output any new values of its own.

For example, a SpringNode is considered finished when its inputs are finished and the spring is at rest. A TimingNode is considered finished when its inputs are finished and it's reached the end of its duration.
