This class may initialized from string data (which may include NULs).
-It has the following methods, supported mainly for internal use by the

+The primary acess to the content of a \class{Binary} object is
+provided by an attribute:
-\begin{methoddesc}{decode}{string}
+\begin{memberdesc}[Binary]{data}
+The binary data encapsulated by the \class{Binary} instance. The data
+is provided as an 8-bit string.
+\end{memberdesc}

+
+\begin{methoddesc}[Binary]{decode}{string}
Accept a base64 string and decode it as the instance's new data.
\end{methoddesc}
-\begin{methoddesc}{encode}{out}
+\begin{methoddesc}[Binary]{encode}{out}
Write the XML-RPC base 64 encoding of this binary item to the out
