TransientNode

class liesel.model.nodes.TransientNode(*inputs, _name='', _needs_seed=False, **kwinputs)

Bases: Node

A node that does not cache its value.

A transient node is outdated if and only if at least one of its input nodes is outdated. The outdated property checks this condition on-the-fly.
