All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class ResultSetMappingQuery
extends ObjectBuildingQuery

Purpose: Concrete class to perform read using raw SQL and the SQLResultSetMapping.

Responsibilities: Execute a selecting raw SQL string. Returns a List of results. Each item in the list will be another list consisting of the expected populated return types in the order they were specified in the SQLResultSetMapping

Overrides:

clone in class DatabaseQuery

convertClassNamesToClasses

public void convertClassNamesToClasses(java.lang.ClassLoader classLoader)

INTERNAL: Convert all the class-name-based settings in this ResultSetMapping to actual class-based settings. This method is used when converting a project that has been built with class names to a project with classes.

Overrides:

convertClassNamesToClasses in class ObjectBuildingQuery

Parameters:

classLoader -

setSQLResultSetMapping

public void setSQLResultSetMapping(SQLResultSetMapping resultSetMapping)

PUBLIC: This will be the SQLResultSetMapping that is used by this query to process the database results

buildObjectsFromRecords

protected java.util.List buildObjectsFromRecords(java.util.List databaseRecords)

INTERNAL: This method is used to build the results. Interpreting the SQLResultSetMapping.

executeDatabaseQuery

public java.lang.Object executeDatabaseQuery()
                                      throws DatabaseException

INTERNAL: Executes the prepared query on the datastore.

Specified by:

executeDatabaseQuery in class DatabaseQuery

Returns:

- the result of executing the query.

Throws:

DatabaseException - - an error has occurred on the database.

prepare

protected void prepare()

INTERNAL: Prepare the receiver for execution in a session.

Overrides:

prepare in class ReadQuery

getSQLResultSetMapping

public SQLResultSetMapping getSQLResultSetMapping()

PUBLIC: This will be the SQLResultSetMapping that is used by this query to process the database results

getSQLResultSetMappingName
