public class CompositeRequestCondition extends AbstractRequestCondition<CompositeRequestCondition>
RequestCondition
contract by delegating to multiple
RequestCondition
types and using a logical conjunction (' && ') to
ensure all conditions match a given request.
When CompositeRequestCondition
instances are combined or compared
they are expected to (a) contain the same number of conditions and (b) that
conditions in the respective index are of the same type. It is acceptable to
provide null
conditions or no conditions at all to the constructor.
