About OpenWire

OpenWire is a free open source library. The library allows writing advanced VCL and FireMonkey components for rapid codeless application development. The components developed with the library allow creation of complex applications with zero lines of program code.

The above image visualizes OpenWire properties. The application shown is a fully functional audio-video processing application with user interface and file selection dialog, written with zero lines of code.  The the AVIPlayer and the audio-to-real converter as well as the scope and image displays -- everything communicates over OpenWire connections that you chain together at design time. There is no code whatsoever involved in implementing the application!

OpenWire is now available on GitHibhttps://github.com/bmitov/OpenWire . An GIT repository is used. We are in process of adding all the source files.
 
You can access the GIT repository here: https://github.com/bmitov/OpenWire.git directly or by using GIT.
 
Please let us know if you are interested in contributing to the project development so we can consider adding you to the list of project members.

 


Our component libraries come in 3 versions a VCL - Firemonkey version (for Delphi / C++ Builder / RAD Studio 10.3 or higher), an MFC compatible Visual C++ version, and a .NET 4.0 supporting Visual Studio 2005 or higher.
 
The RAD Studio version is a set of native VCL and Firemonkey components of which all include now the powerful Mitov Runtime.
 
The Visual C++ version is a set of native Visual C++ classes (components).
 
The NET 4.0 (4.5 and higher compatible) version is a set of managed .NET components.  The .NET version has the same performance as the native versions, and supports all the Microsoft .NET languages including Visual Basic, C#, J#, F# and C++/CLI.
 
Due to the unique architecture of the OpenWire platform, the components are implemented the same way in Managed .NET and native Windows (32 and 64 bit) environments. The code to control a component from VB.NET, C++/CLI, C#, and J#, Visual C++ MFC, Delphi, and C++ Builder is almost identical. This allows the developers to migrate and share code between the different environments thus significantly improving the productivity.

OpenWire itself is FREE Open Source project.  Below is a brief description of some of the features of the current OpenWire version. The full documentation is available as a Word document.

 
The purpose of the OpenWire project is to introduce a unified, easy way to transfer data among different VCL or FireMonkey components. This is very similar to the way that products like LabView and HP VEE work.  For example, you could quickly build an application with a sine wave generator, which streams out to a chart and in parallel to a filter, which streams out to another chart and in parallel to a file logger, as well as to a serial communication sending the data to another system.  And what makes this easy is that you do not write code: You build streams by connecting an OutputPin to one or more InputPins.  The underlying technology pumps your data from pin to pin, using multiple threads for high performance.
 
OutputPins and InputPins can be viewed as connectors on the edges of components -- and Mitov Software offers a vast array of custom components on multiple platforms; or, you can build your own.
 
Features of OpenWire Componets:
 
  • Each component can have one or more inputs and/or outputs.
  • Each Input or Output is called Pin. I.E. there are IputPins and OutputPins.
  • Each OutputPin can stream specific format data to compatible format InputPins.
  • Each type of data has its own data specification.
 
The data specification is a globally unique data type identifier.  For example, the integer data type has one type of data specification and the String data type has a different one. An OutputPin can be specified as being able to stream one or many types of data.  For example, you could have an OutputPin that sends file names and streams String data. Any InputPin accepting Strings will be able to connect and receive from this Pin, and any Pin accepting file names will be able to connect and receive, too.  Specifically:
 
  • Each Pin is a property cloned from TOWPin.
  • The InputPin is inherited from TOWPin and the are called TOWSinkPin.
  • The OutputPin is inherited from TOWPin and the are called TOWSourcePin.
  • The InputPin and OutputPin are responsible for implementing one or many stream specific inerface(s). The interface has a unique GUID specified for that type of stream.
  • The InputPin and OutputPin have data specification which describes what type of data types (interfaces) it can accept (connect to).
  • The data specification for a certain data type contains in the TPinType object.
  • The TPinType contains one or more entries of type TGUID.
  • The TGUID is used to determine the type of data - it’s in fact the GUID of the interface being able to connect to that type of data.
 
There is a handshaking mechanism involved during the connection of 2 Pins. Only compatible data type Pins can be connected. Otherwise the connection is rejected. There are property editors which are allowing you to connect the Pins. You can connect 2 Pins at run time as well.
 
OpenWire 2.x adds StatePins. StatePins can be connected together by creating hidden objects named StateDispatchers(States). The StatePins share one and the same state. If a the state of one of the StatePins changes all the connected StatePins are changing to the same state. StatePins can be connected to one SourcePin, and/or to multiple SinkPins.

OpenWire: Frequently Asked Questions

Q: Can I use OpenWire in a non open source commercial application or component library?
A:

Yes you can use OpenWire in non open source applications and component libraries.

Q: Can I write multithreading applications using OpenWire? Is it multithreading safe?
A:

Yes. The latest version of OpenWire is fully multithread safe, and is used in heavily multithreaded solutions.

Q: Why do I see only few simple components when I install OpenWire? Where are the OpenWire components?
A:

OpenWire is a library of properties called Pins. It does not provide components, just properties for writing such components. The components you see are demo components provided to you to learn how to use OpenWire in your components.
