This class is thread safe. See Also:   org.apache.commons.dbutils.ResultSetHandler Constructor Summary public   ScalarHandler()      Creates a new instance of ScalarHandler. public   ScalarHandler(int columnIndex)      Creates a new instance of ScalarHandler. public   ScalarHandler(String columnName)      Creates a new instance of ScalarHandler. Method Summary public  Object handle(ResultSet rs)      Returns one ResultSet column as an object via the ResultSet.getObject() method that performs type conversions. Constructor Detail ScalarHandler public ScalarHandler()(Code) Creates a new instance of ScalarHandler. The first column will be returned from handle(). ScalarHandler public ScalarHandler(int columnIndex)(Code) Creates a new instance of ScalarHandler. Parameters:   columnIndex - The index of the column to retrieve from the ResultSet. ScalarHandler public ScalarHandler(String columnName)(Code) Creates a new instance of ScalarHandler. Parameters:   columnName - The name of the column to retrieve from the ResultSet. Method Detail handle public Object handle(ResultSet rs) throws SQLException(Code) Returns one ResultSet column as an object via the ResultSet.getObject() method that performs type conversions. The column or null if there are no rows inthe ResultSet. throws:   SQLException - if a database access error occurs See Also:   org.apache.commons.dbutils.ResultSetHandler.handle(java.sql.ResultSet) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
