                        throws java.lang.Throwable

Invoke method on a specified proxy. Here we check if method is a method Statement.close(). If yes, we notify owner that this prepared statement was closed.

Specified by:
invoke in interface java.lang.reflect.InvocationHandler
Parameters:
proxy - proxy on which method is invoked.
method - instance of Method describing method being invoked.
args - array with arguments.
Returns:
result of method invokation.
Throws:

protected void checkCorrectness(java.lang.reflect.Method method)
                         throws java.sql.SQLException
Deprecated. 
Check if method call is correct. If method was declared in PreparedStatement class and there is no connection proxy associated with this statement (i.e. statement in in pool), exception is thrown (this situation usually happens if somebody tries to call method on prepared statement after it has been closed).

Parameters:
method - method to check.
Throws:
java.sql.SQLException - if statement has incorrect statement.
