Virtual Rule Functions and VRF Catalog Functions
The VRF category of functions (within the standard functions) are used only with TIBCO BusinessEvents Decision Manager.
The VRF category of functions provide flexibility when you are working with virtual rule function implementations. Virtual rule functions are implemented by decision tables.
Note: When you deploy multiple implementations (tables) for one virtual rule function, but use a function that doesn’t specify the implementation by name, for example if you use
Functions.MyVirtualRuleFunction(), the default implementation is used. The default implementation is whichever was the last implementation to be deployed. However, if you use hot deployment, it may not be possible to determine which implementation was deployed last.
The VRF category of functions contains the following:
getVRFImplByName() getVRFImplNames() getVRFImpls() invokeAllVRFImpls() invokeVRFImpl() invokeVRFImplByName() invokeVRFImpls()
- Adding a Virtual Rule Function
To add a virtual function, perform the following steps.
