MessageQueue

Abstract Value Members

abstract def +=(message: InternalMessage): Unit

Add a message onto the queue.
Add a message onto the queue. Note that this doesn't do any deduplication, that should've happened in an earlier step.
message
The message to add onto the queue
abstract def byId: Map[String, InternalMessage]

Get the messages indexed by their unique id
Get the messages indexed by their unique id
returns
The messages indexed by their id
abstract def clear(): Unit

Drop all messages on the queue
abstract def dequeue(count: Int, deliveryTime: Long): List[InternalMessage]

Dequeues count messages from the queue
Dequeues count messages from the queue
count
The number of messages to dequeue from the queue
deliveryTime
The timestamp from which messages should be available (usually, this is the current millis since epoch. It is useful to pass in a special value during the tests however.)
returns
The dequeued messages, if any
abstract def filterNot(p: (InternalMessage) ⇒ Boolean): MessageQueue

Return a message queue where all the messages on the queue do not match the given predicate function
Return a message queue where all the messages on the queue do not match the given predicate function
p
The predicate function to filter the message by. Any message that does not match the predicate will be retained on the new queue
returns
The new message queue
abstract def remove(messageId: String): Unit

Remove the message with the given id
Remove the message with the given id
messageId
The id of the message to remove

final def nextVisibleMessage(priorityQueue: PriorityQueue[InternalMessage], deliveryTime: Long, accBatch: List[InternalMessage], accMessage: Seq[InternalMessage] = Seq.empty): Option[InternalMessage]

Get the next available message on the given queue
Get the next available message on the given queue
priorityQueue
The queue for which to get the next available message. It's assumed the messages on this queue all belong to the same message group.
deliveryTime
The timestamp from which messages should be available
accBatch
An accumulator holding the messages that have already been retrieved.
accMessage
An accumulator holding the messages that have been dequeued from the priority queue and cannot be delivered. These messages should be put back on the queue before returning to the caller
