The queue services supported by Zend_Queue do
not all support the same functions. For example,
Zend_Queue_Adapter_Array,
Zend_Queue_Adapter_Db, support all functions,
while Zend_Queue_Adapter_Activemq does not
support queue listing, queue deletion, or counting of messages.
You can determine what functions are supported by using
Zend_Queue::isSupported() or
Zend_Queue::getCapabilities().

receive() methods are employed by each

The createQueue() and

queues.
