class UnifiedQueues::Single::Driver::PoorPriorityQueueDriver
Minimal priority queue driver. Uses the PoorPriorityQueue
class from PriorityQueue
gem. Priority is supported.
It isn't implement equivalent of the #clear
method, so it falls backs to naive “popping” style clearing.
Also note, it's very minimalistic implementation, so both calls to {PoorPriorityQueue#length} and {PoorPriorityQueue#empty?} will throw an exception.
Public Instance Methods
Indicates queue is empty. Note, it isn't implemented in this implementation.
@param [Boolean] true
if it's, false
otherwise

Returns length of the queue. Note, it isn't implemented in this implementation.
@return [Integer]

Pops value out of the queue. Note, value with minimal priority will be popped out. Blocking isn't supported.
@param [Boolean|Integer] blocking true
or timeout if it should block, false
otherwise @return [Object] queued value
# File lib/unified-queues/single/driver/priority_queue.rb, line 123 def pop(blocking = false) @native.delete_min_return_key end
