xdc.services.getset.Getters
public class Getters
A getter function to be added to a field of an XDCscript Value.Obj object. The Getters service manages a set of user-defined getter functions that notifies client code of reads from the field.
There is also a set of global user-defined getter functions that are notified on any read. This avoids having to manually add such getters to every field. Note, though, that the global getters only apply to fields that have had the Getters service added to them. The JavaScript getter functions have the signature:this.function(name, value) this is set to the object whose field was read name is the name of the field that was read value is the value that will be returned by the read
