Modular application

Today many applications are converted into N-tier structure and here modular structure is very useful and DS Plug-in System provides support for such functionality.

You can read more about N-tier structure in my articles. Please refer to articles section for more details.

During this years we've been tried accumulate all functionality you could expect from Plug-In model.
Please see feature list and documentation for more details.

Description

System is based on TDataModule structure and provide you with flexible way to manage your plug-ins. You can create them as a BPL or DLL; you could mix them in your application.

System provides you with Delphi IDE wizard to help you create initial code for your Plug-in, after this you could extend functionality in any ways.

Structure of the system allows you create independent as well as dependant plug-ins. In second case you could specify plug-in dependency, which means plug-in itself will control environment it runs in and inform you (plug-in manager) when required information is missed. This could help you handle many situations when system became unstable because some components of system not available as well as allow you handle intermodular dependency during load process.

One more advantage of the system is its real time configuration.

You can register and unregister plug-ins at any time.

You can load and unload plug-ins at any time.

System supports thread-safe mechanism and provides you with lock/unlock functionality.
