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

Constructor Detail

ResultSetMappingQuery

public ResultSetMappingQuery()

PUBLIC: Initialize the state of the query.

ResultSetMappingQuery

public ResultSetMappingQuery(Call call)

PUBLIC: Initialize the query to use the specified call.

ResultSetMappingQuery

public ResultSetMappingQuery(Call call,
                     java.lang.String sqlResultSetMappingName)

PUBLIC: Initialize the query to use the specified call and SQLResultSetMapping

Method Detail

cacheResult

public void cacheResult(java.lang.Object unwrappedOriginal)

INTERNAL:

This method is called by the object builder when building an original. It will cause the original to be cached in the query results if the query is set to do so.

Specified by:

cacheResult in class ReadQuery

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

setSQLResultSetMapping

public void setSQLResultSetMapping(SQLResultSetMapping resultSetMapping)

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

setSQLResultSetMappingName

public void setSQLResultSetMappingName(java.lang.String name)

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

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.

getSQLResultSetMapping

public SQLResultSetMapping getSQLResultSetMapping()

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

getSQLResultSetMappingName

public java.lang.String getSQLResultSetMappingName()

PUBLIC: Return the result set mapping name.
