public Object readObject () throws SQLException [Specified in SQLInput]

Retrieves the value at the head of this SQLInputImpl object as an Object in the Java programming language.

Retrieves the value at the head of this SQLInputImpl object as an Object in the Java programming language. The actual type of the object returned is determined by the default mapping of SQL types to types in the Java programming language unless there is a custom mapping, in which case the type of the object returned is determined by this stream's type map.

The JDBC technology-enabled driver registers a type map with the stream before passing the stream to the application.

When the datum at the head of the stream is an SQL NULL, this method returns null. If the datum is an SQL structured or distinct type with a custom mapping, this method determines the SQL type of the datum at the head of the stream, constructs an object of the appropriate class, and calls the method SQLData.readSQL on that object. The readSQL method then calls the appropriate SQLInputImpl.readXXX methods to retrieve the attribute values from the stream.
