Class: ProcessingPhase Abstract

Defined in:

src/kermit/RequestItem.coffee

Overview

This class is abstract.

A RequestItem is always in one of the following processing phases. Each item starts with phase {ProcessingPhase.INITIAL} From phase INITIAL it transitions forward while being processed by the Extensions that handle items of that particular phase. The following diagram illustrate the possible phase transitions with the ordinary flow INITIAL -> SPOOLED -> READY -> FETCHING -> FETCHED -> COMPLETE. Any item may also end in phases CANCELED or ERROR depending on the logic of the Extensions
