/* - A tlm_generic_payload object should be constructed after C++ */
/* static initialization time. This way it is guaranteed that the */
/* extension array is of sufficient size to hold all possible */
/* extensions. Alternatively, the initiator module can enforce a valid */
/* extension array size by calling the resize_extensions() method */
/* once before the first transaction with the payload object is */
/* initiated. */
/* */
/* - Initiators should use the the set_extension(e) or clear_extension(e)*/
/* methods for manipulating the extension array. The type of the */
/* argument must be a pointer to the specific registered extension */
/* type (my_extension in the above example) and is used to */
/* automatically locate the appropriate index in the array. */
