LabVIEW Interface is a kind of class library that implements the concept of interfaces in LabVIEW. An interface defines a contract between the caller and the callee. Any class that inherits from an interface declares that it will provide all methods defined by that interface. In LabVIEW a class may have only one class parent and as many interface parents as it wants to have.[1] An interface may also inherit from one or more other interfaces.
Key features
- Interfaces use the same file extension as classes (*.lvclass).
- Interfaces have their own unique icon (
) in the Project Explorer. - Interfaces use the same default ("chain") wire appearance as classes.
- Interfaces are created and changed using the same dialogs as classes.
- Interfaces can provide default implementations for their methods.
- Classes do not inherit the interface library icon or wire appearance.
- Call Parent Class Method cannot invoke interface parent methods.
Best practice
- Do not use the leading "I" when naming interfaces.[1]
