| ResultObjectFactoryUtil | | public class ResultObjectFactoryUtil (Code) | | This class is used to create instances of result objects. It will
use the configured ResultObjectFactory if there is one, otherwise
it will use iBATIS' normal methods.
Note that this class is somewhat tightly coupled with
SqlExecuter - SqlExecute must call the setStatementId() and
setResultObjectFactory() methods before executing a statement.
This is a result of using a ThreadLocal to hold the current
configuration for the statement under execution. Using a
ThreadLocal is a solution for IBATIS-366. Without a ThreadLocal,
the current factory and statement id would have to be added to
many method signatures - often in inappropriate places.

| Method Summary | |
| public static Object | createObjectThroughFactory(Class clazz)
Algorithm:
- If factory is null, then create object internally()
- Otherwise try to create object through factory
- If null returned from factory, then create object internally
This allows the factory to selectively create objects, also allows for
the common possibility that a factory is not configured.
Parameters:
factory - the factory to use. | | public static void | setResultObjectFactory(ResultObjectFactory resultObjectFactory)
| | public static void | setStatementId(String statementId)
|
| createObjectThroughFactory | | public static Object createObjectThroughFactory(Class clazz) throws InstantiationException, IllegalAccessException(Code) | | Algorithm:
- If factory is null, then create object internally()
- Otherwise try to create object through factory
- If null returned from factory, then create object internally
This allows the factory to selectively create objects, also allows for
the common possibility that a factory is not configured.
Parameters:
factory - the factory to use. May be null!
Parameters:
statementId - the ID of the statement that generated the call to this method
Parameters:
clazz - the type of object to create a new instance of the specified class. The instance mustbe castable to the specified class.
throws:
InstantiationException - if the instance cannot be created. If you throw this Exception,iBATIS will throw a runtime exception in response and will end.
throws:
IllegalAccessException - if the constructor cannot be accessed. If you throw thisException, iBATIS will throw a runtime exception in response andwill end. |
