Detailed Description

template<class T>
class SST::XdrOption< T >

Template class representing a length-delimited XDR option.

An "option" is our own extension to XDR, similar to XdrPointer in that it represents an optional instance of some other type, but uses a length-delimited encoding rather than just a boolean flag, so that on decode we can skip over a value we can't understand. For encoding purposes an "option" is equivalent to an opaque<>; the purpose of this template class is merely to make it easier to get at the semantic content _within_ the "opaque" field.
