Abstract

An applicant can instantiate a parsing framework, provide an input stream, attach observers, and initiate parsing, which inverts control to the parsing framework. The parsing framework can have an observer manager, a parser controller, and parsers. The observer manager manages observer design patterns from which the observers are instantiated. The parser controller determines which parser would be appropriate for parsing the input stream and instantiate the appropriate parser(s). The parser controller gets the callbacks from the parsers and communicates outcomes to the observer manager. The observer manager determines which of the observers is to be notified, generates parsing notifications accordingly, and dispatches the parsing notifications directly to the observers. The application can be any application that needs parsing in an electronic information exchange platform. The input stream can be created by the application opening a document received from a backend system communicatively connected to the electronic information exchange platform.

Dependent claims

A method, comprising:

receiving, by a parsing framework embodied on non-transitory computer memory, an input stream from an application, the application having observers, each observer associated with a function of the application, the parsing framework comprising an observer manager, a parser controller, and a plurality of parsers, the observation manager structurally insulating the plurality of parsers from the application and the observers, wherein the application attaches the observers to the parsing framework and initiates parsing of the input stream by the parsing framework and wherein control of the parsing is inverted to the parsing framework;
determining a parser of the plurality of parsers based at least in part on a format of the input stream, the determining performed by the parser controller;
instantiating the parser thus determined, the instantiating performed by the parser controller;
parsing the input stream, the parsing performed by the parser determined by the parser controller;
determining which of the observers is to be notified of an outcome from the parsing, the determining performed by the observer manager;
generating at least one parsing notification, the generating performed by the observer manager;
and
dispatching the at least one parsing notification directly to any or all of the observers determined by the observer manager of the parsing framework to be notified of the outcome from the parsing, the dispatching performed by the observer manager.
