Method Detail

toArray

public java.lang.Object[] toArray(java.sql.ResultSet rs)
                           throws java.sql.SQLException
Create an Object[] from the column values in one ResultSet row. The ResultSet should be positioned on a valid row before passing it to this method. Implementations of this method must not alter the row position of the ResultSet.

Throws:
java.sql.SQLException

toBean

public java.lang.Object toBean(java.sql.ResultSet rs,
                               java.lang.Class type)
                        throws java.sql.SQLException
Create a JavaBean from the column values in one ResultSet row. The ResultSet should be positioned on a valid row before passing it to this method. Implementations of this method must not alter the row position of the ResultSet.

Throws:
java.sql.SQLException

toBeanList

public java.util.List toBeanList(java.sql.ResultSet rs,
                                 java.lang.Class type)
                          throws java.sql.SQLException
Create a List of JavaBeans from the column values in all ResultSet rows. ResultSet.next() should not be called before passing it to this method.

Returns:
A List of beans with the given type in the order they were returned by the ResultSet.
Throws:
java.sql.SQLException

toMap

public java.util.Map toMap(java.sql.ResultSet rs)
                    throws java.sql.SQLException
Create a Map from the column values in one ResultSet row. The ResultSet should be positioned on a valid row before passing it to this method. Implementations of this method must not alter the row position of the ResultSet.

Throws:
java.sql.SQLException
