static boolean IsEquivalent( DataView view1, DataView view2 )
If the two variables refer to the same data view, the return value is true. If either variable is null or the variables refer to different data views, the return value is false.
DataView view1
An object of a DataView-derived class.
DataView view2
An object of a DataView-derived class.
Use this method to determine whether two objects of the DataView class refer to the same data view. This method is usually used in conjunction with the method DataView.GetInitiator to determine whether the initiator of an action is a particular known DataView.
Technical Note: This method does not return the same values as the Java method Object.equals. The DataView objects that an IMLPlus programmer manipulates are actually proxies for data views. It is possible to have multiple proxies that refer to the same data view.
