Description
Copies the properties of one index definition to another.
Call Assign to copy another index definition. Assign checks whether the ASource parameter is another index definition, and, if so, copies the values of the Options, Name, Source, Expression, and Fields properties.
If the source is not an index definition, Assign calls the inherited (Delphi) or parent class's (C++) method, which assigns properties from any object that specifies how to copy to an index definition in its AssignTo method.
