A system includes a memory and a processor in communication with the memory. The processor is configured to process at least one application file and generate bytecode, responsive to processing the at least one application file, from the at least one application file prior to start-up time. The bytecode contains a metamodel and the metamodel controls dependency injection. Additionally, the metamodel is classified as at least one of a first class that is generated at start-up time, a second class that is generated as source files and compiled at compile time, and a third class that is generated directly as bytecode. The processor is also configured to store the bytecode associated with the third class of metamodel.

Implementing dependency injection via direct bytecode generation

A method includes receiving an application, where the application includes an extension and a metadata model. The method also includes instantiating the extension and firing an event. The method also includes upon detecting the event at the instantiated extension, creating metadata associated with the application, collecting the metadata associated with the application, and revising the metadata model based on the collected metadata.
