The reflect.Value class

The reflect.Value class is a generic API to inspect and modify variables.

This class is provided in the reflect C-Extension library; To use this class, import the reflect package with:
IMPORT reflect

A reflect.Value object is the runtime representation of a variable.

A call to reflect.Value returns an object representing the type and data of a variable at runtime.

Each variable has a Type. Several methods of this API are restricted to certain kinds of Types. For example, the method insertArrayElement() is restricted to the kind "ARRAY". The program should check the kind of a type before calling kind-specific functions.

Important: The exceptions thrown by the reflect.* API can only be caught with a TRY/CATCH block: If WHENEVER ERROR CONTINUE is active and the reflection API throws an exception, the program stops.
