<a name="readObject"><b>readObject</b></a>
<pre>
 public Object readObject() throws SQLException
</pre>
<dl>
  <dd> Return the datum at the head of the stream as a Java object.  The 
actual type of the object returned is determined by the default type
mapping, and any customizations present in this stream's type map.
A type map is registered with the stream by the JDBC driver before the
stream is passed to the application.
When the datum at the head of the stream is an SQL NULL, 
the method returns null.  If the datum is an SQL structured or distinct
type, it determines the SQL type of the datum at the head of the stream, 
constructs an object of the appropriate class, and calls method 
SQLData.readSQL on that object, which reads additional data from the 
stream, using the protocol described for SQLData.readSQL.
