class node_filter_list.FilterListPredicate[source]

Filter nodes with predicate takes a configurable predicate function (a function that returns True or False) from the configuration and uses it to decide which inputs to include in the output.

The function is applied for each input element in the list and for each element where the function returned True the element is also included in the output.

Examples (with table as the element type):

Remove tables with zero length columns:

lambda table: table.number_of_columns() > 0

Remove empty tables:

lambda table: not table.is_empty()

Partition a list of ADAFs using a predicate.
