AMQP is a binary application layer protocol, designed to efficiently support a wide variety of messaging applications and communication patterns. It provides flow controlled, [3] message-oriented communication with message-delivery guarantees such as at-most-once (where each message is delivered once or never), at-least-once (where each message is certain to be delivered, but may do so ...
Although reserved as a keyword in Java, goto is not used and has no function. [2] [26] strictfp (added in J2SE 1.2) [4] Although reserved as a keyword in Java, strictfp is obsolete, and no longer has any function.

The IMAP protocol includes the IDLE command, which allows the server to tell the client when new messages arrive. The original BlackBerry was the first popular example of push-email in a wireless context. [citation needed] Another example is the PointCast Network, which was widely covered in the 1990s. It delivered news and stock market data as ...
push 1L (the number one with type long) onto the stack ldc 12 0001 0010 1: index → value push a constant #index from a constant pool (String, int, float, Class, java.lang.invoke.MethodType, java.lang.invoke.MethodHandle, or a dynamically-computed constant) onto the stack ldc_w 13 0001 0011 2: indexbyte1, indexbyte2 → value
Push–pull (pipeline) Connects nodes in a fan-out / fan-in pattern that can have multiple steps, and loops. This is a parallel task distribution and collection pattern. Exclusive pair Connects two sockets in an exclusive pair. (This is an advanced low-level pattern for specific use cases.) Each pattern defines a particular network topology.
In software architecture, publish–subscribe or pub/sub is a messaging pattern where publishers categorize messages into classes that are received by subscribers. This is contrasted to the typical messaging pattern model where publishers send messages directly to subscribers.
Command-line argument parsing is the process of analyzing and handling command-line input provided to a program.
