google.appengine.datastore.datastore_query.CompositeFilter

An immutable filter predicate that combines other predicates.

Inherits From: FilterPredicate, expected_type

google.appengine.datastore.datastore_query.CompositeFilter(
    op, filters
)

This class proactively merges sub-filters that are combined using the same operator. For example: CompositeFilter(AND, [f1, f2, CompositeFilter(AND, [f3, f4]), f5, f6]) is equivalent to: CompositeFilter(AND, [f1, f2, f3, f4, f5, f6])

Currently filters can only be combined using an AND operator.

op The operator to use to combine the given filters
filters A list of one or more filters to combine

datastore_errors.BadArgumentError if op is not in CompsiteFilter.OPERATORS or filters is not a non-empty list containing only FilterPredicates.
