EXTENSIBLE LANGUAGE FRAMEWORK USING DATA CARTRIDGES
First Claim
1. A method comprising:
- receiving, by a computer system, a query expressed in an event processing language, the query including a reference to a complex type implemented in another language distinct from the event processing language; and
compiling, by the computer system, the query by;
retrieving metadata pertaining to the complex type from information stored in a data cartridge for the complex type; and
generating, based on the metadata, executable instructions for executing the query.

Abstract
A framework for extending the capabilities of an event processing system using one or more plug-in components referred to herein as data cartridges. In one set of embodiments, the data cartridge framework described herein can enable an event processing system to support one or more extension languages that are distinct from the native event processing language supported by the system. For example, certain “extension language” data cartridges can be provided that enable an event processing system to support complex data types and associated methods/operations that are common in object-oriented languages, but are not common in event processing languages. In these embodiments, an event processing system can access an extension language data cartridge to compile and execute queries that are written using a combination of the system'"'"'s native event processing language and the extension language.
