SYNCHRONIZING PROPERTY CHANGES TO ENABLE MULTIPLE CONTROL OPTIONS

Components in an information processing system are represented by software objects whose properties can be changed through function calls. Setting a property of an object controls the associated component. Properties are connected through routes that propagate state changes throughout the system without the need for a running client application. Two-way property routes are used to keep consistence among a controlled object and multiple controlling objects without the risk of endless loops. To achieve this, the two-way route is executed to change a state of a specific one of the properties upon a change of state of another one of the properties if the change of state of the other property was caused by an effect other than the route itself.
