Class CompositeRange

java.lang.Object

com.gigaspaces.internal.query.AbstractCustomQuery

com.j_spaces.jdbc.builder.range.Range

com.j_spaces.jdbc.builder.range.CompositeRange

All Implemented Interfaces:

ICustomQuery, Externalizable, Serializable

Direct Known Subclasses:

ContainsCompositeRange

public class CompositeRange
extends Range

CompositeRange indicates a result of a complex intersection that can't be translated to a single range. In this case the first range is executed as a query and the remaining ranges used to filter the irrelevant results. This is not very efficient but used only in very specific case: x > 3 and x < 6 and x <> 4
