  2. Jakarta Messaging - Wikipedia

    en.wikipedia.org/wiki/Jakarta_Messaging

    The Jakarta Messaging API (formerly Java Message Service or JMS API) is a Java application programming interface (API) for message-oriented middleware. It provides generic messaging models, able to handle the producer–consumer problem , that can be used to facilitate the sending and receiving of messages between software systems . [ 1 ]

  3. Message queue - Wikipedia

    en.wikipedia.org/wiki/Message_queue

    It sleeps until another message is posted in the queue, and then wakes up to check again. Non-blocking receive returns immediately to the caller, mentioning that it failed. msgctl() Used to change message queue parameters like the owner. Most importantly, it is used to delete the message queue by passing the IPC_RMID flag. A message queue can ...

  4. Queue (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Queue_(abstract_data_type)

    A bounded queue is a queue limited to a fixed number of items. [1] There are several efficient implementations of FIFO queues. An efficient implementation is one that can perform the operations—en-queuing and de-queuing—in O(1) time. Linked list. A doubly linked list has O(1) insertion and deletion at both ends, so it is a natural choice ...

  5. Priority queue - Wikipedia

    en.wikipedia.org/wiki/Priority_queue

    STL also has utility functions for manipulating another random-access container as a binary max-heap. The Boost libraries also have an implementation in the library heap. Python's heapq module implements a binary min-heap on top of a list. Java's library contains a PriorityQueue class, which implements a min-priority-queue as a binary heap.

  6. Double-ended queue - Wikipedia

    en.wikipedia.org/wiki/Double-ended_queue

    Double-ended queues can also be implemented as a purely functional data structure. [3]: 115 Two versions of the implementation exist. The first one, called 'real-time deque, is presented below. It allows the queue to be persistent with operations in O(1) worst-case time, but requires lazy lists with memoization. The second one, with no lazy ...

  8. Actor model - Wikipedia

    en.wikipedia.org/wiki/Actor_model

    The actor model in computer science is a mathematical model of concurrent computation that treats an actor as the basic building block of concurrent computation. In response to a message it receives, an actor can: make local decisions, create more actors, send more messages, and determine how to respond to the next message received.

  9. Min-max heap - Wikipedia

    en.wikipedia.org/wiki/Min-max_heap

    This makes the min-max heap a very useful data structure to implement a double-ended priority queue. Like binary min-heaps and max-heaps, min-max heaps support logarithmic insertion and deletion and can be built in linear time. [3] Min-max heaps are often represented implicitly in an array; [4] hence it's referred to as an implicit data structure.
