openpathsampling.treelogic.TreeMixin

class openpathsampling.treelogic.TreeMixin

A mixin that provides basic tree handling.

A tree is basically a node with children of the same type. The mixin requires to implement .subnodes to contain a list of children.

The __contains__ operator requires _default_match to be implemented. Otherwise is defaults to a comparison between two elements.
