Enclosing class:

Query

public static final class Query.CompositeFilter
extends Query.Filter

A Query.Filter that combines several sub filters using a Query.CompositeFilterOperator.

For example, to construct a filter of the form a = 1 AND (b = 2 OR c = 3) use:

 new CompositeFilter(CompositeFilterOperator.AND, Arrays.asList(
     new FilterPredicate("a", FilterOperator.EQUAL, 1),
     new CompositeFilter(CompositeFilterOperator.OR, Arrays.<Filter>asList(
         new FilterPredicate("b", FilterOperator.EQUAL, 2),
         new FilterPredicate("c", FilterOperator.EQUAL, 3)))));
 

or

 CompositeFilterOperator.and(
     FilterOperator.EQUAL.of("a", 1),
     CompositeFilterOperator.or(
         FilterOperator.EQUAL.of("b", 2),
         FilterOperator.EQUAL.of("c", 3)));
