Method Detail

init

public void init(java.sql.ResultSet result)
          throws java.sql.SQLException,
                 PersistenceException

Description copied from interface: IResultSetProcessor

Initializes the ResultSet. For instance, scrolls down to the correct first record etc.

Specified by:

init in interface IResultSetProcessor

Parameters:

result - The ResultSet to initialize.

Throws:

java.sql.SQLException - If the intialization fails.

PersistenceException - If something else fails during initialization.

process

public void process(java.sql.ResultSet result,
                    IDaos daos)
             throws java.sql.SQLException,
                    PersistenceException

Description copied from interface: IResultSetProcessor

Processes a record in the ResultSet. For instance reads the column values into a List, Map, or some other object. This method is called for each record in the ResultSet.

Specified by:

process in interface IResultSetProcessor

Parameters:

result - The ResultSet to process the record of.

daos - The IDaos instance where the IJdbcDao that called this method belongs to. Use it to, for instance, read an object from the current record using the IGenericDao.read(objectMappingKey, ResultSet).

Throws:

java.sql.SQLException - If something fails in the driver during the processing of the current record.

PersistenceException - If something else fails during the processing.

setResult

protected void setResult(java.lang.Object object)

getResult

public java.lang.Object getResult()
                           throws PersistenceException

Description copied from interface: IResultSetProcessor

Returns the result of the total processing. For instance, if the process method reads records into object and add them to a List, this method will return the List.

Specified by:

getResult in interface IResultSetProcessor

Returns:

The result of the total processing of the ResultSet.

Throws:

PersistenceException - If for some reason the returning of the result fails. This could be if the getResult() method builds a complex object from records read, and that this somehow fails (missing records, or invalid values).
