handledprocessed

Handledprocessed is a coined term used in software engineering to describe the state of an input, event, or message that has both been handled by a component and has completed its processing phase. It is not a formal standard, but appears as a name for a boolean flag, property, or enum in various codebases to indicate completion of two related steps in a pipeline: handling and processing.

Definitions: Handled refers to the stage where an event is recognized and routed to an appropriate handler; Processing refers to the actual work performed, such as transformation, I/O, or side effects. The combined state “handledprocessed” implies that the event has passed through both steps and is considered finished for the concerned subsystem.

Usage: In event-driven or asynchronous systems, a handledprocessed flag can help prevent duplicate work by ensuring downstream components only act after both steps. It may be implemented as a three-state or four-state enum, or as two booleans. The pattern is prone to ambiguity, so clear semantics should be documented, especially in multi-threaded contexts where race conditions may occur.

Relation to similar concepts: Acknowledgement, consumption, and idempotency are related. Some systems distinguish “handled” and “processed” for clarity, while others treat their combination as “completed” or “consumed.”

Notes: Since handledprocessed is not standardized, its exact meaning can vary between teams; avoid relying on the term for public APIs without explicit definition.
