public class Count
extends AggregateExpression
implements org.jvnet.jaxb2_commons.lang.Equals2, org.jvnet.jaxb2_commons.lang.HashCode2, org.jvnet.jaxb2_commons.lang.ToString2

The Count operator returns the number of non-null elements in the source. If a path is specified, the count returns the number of elements that have a value for the property specified by the path. If the list is empty, the result is 0. If the list is null, the result is 0.
