Function Details | [hide private]

### get_composed_filter(*filters)

Returns a node filter that is the composition of all filter functions passed as arguments. Filters will be applied in the order they appear.

### get_reverse_filter(node_filter)

Returns a new filter that lets throught all nodes normally filtered out by node_filter, and filters out the one normally passed.

This should be useful only with filters that pass nodes through without modifying them.
