System and method for implementing a data-flow based system. The system includes three basic components: a data-flow based scheduling environment that balances the needs of data initiated program execution as a result of flows with other practical considerations such as user responsiveness, event driven invocation, user interface considerations, and the need to also support control-flow based paradigms where required; a visual programming language, based on the flow of strongly-typed run-time accessible data and data collections between small control-flow based locally and network distributed functional building blocks, known as widgets; and a formalized pin based interface to allow access to data-flow contents from the executing code within the widgets. The pins on the widgets include both pins used to control execution of a widget as well as pins used to receive data input from a data flow. |
