Represents a read-only parameter.
It is a wrapper for an instance of real Parameter object.
| Constructor Summary | |
Const(Const t)
Constructs a copy of Const instance. |

protected void acceptIOPerformer(IOPerformer performer,
DataBuffer source,
int initialOffset,
boolean isReadOperation,
boolean invokedByCallback)
Parameterperformer is responsible for I/Oing the
parameter. Users implementing a complex parameter from scratch (i.e. not by extending a pre-existing class
such as Structure or Pointer) may wish to override this method to make a performer
visit object internal parts.
