/*
* The ACPI_OPERAND_OBJECT is used to pass AML operands from the dispatcher
* to the interpreter, and to keep track of the various handlers such as
* address space handlers and notify handlers. The object is a constant
* size in order to allow them to be cached and reused.
*
* All variants of the ACPI_OPERAND_OBJECT are defined with the same
* sequence of field types, with fields that are not used in a particular
* variant being named "Reserved". This is not strictly necessary, but
* may in some circumstances simplify understanding if these structures
* need to be displayed in a debugger having limited (or no) support for
* union types. It also simplifies some debug code in DumpTable() which
* dumps multi-level values: fetching Buffer.Pointer suffices to pick up
* the value or next level for any of several types.
