Interface Return

All Known Implementing Classes:

CollectionReturn, EntityReturn, ScalarReturn

public interface Return

Represents a return value in the query results. Not the same as a result (column) in the JDBC ResultSet!

Return is distinctly different from a Fetch and so modeled as completely separate hierarchy.

Method Summary

Methods

Modifier and Type	Method and Description
void	hydrate(ResultSet resultSet, ResultSetProcessingContext context)
Object	read(ResultSet resultSet, ResultSetProcessingContext context) Essentially performs the second phase of two-phase loading.
void	resolve(ResultSet resultSet, ResultSetProcessingContext context) Effectively performs first phase of two-phase loading.

Method Detail

hydrate

void hydrate(ResultSet resultSet,
           ResultSetProcessingContext context)
             throws SQLException

Throws:

SQLException

resolve

void resolve(ResultSet resultSet,
           ResultSetProcessingContext context)
             throws SQLException

Effectively performs first phase of two-phase loading. For scalar results first/second phase is one. For entities, first phase is to resolve identifiers; second phase is to resolve the entity instances.

Parameters:

resultSet - The result set being processed

context - The context for the processing

Throws:

SQLException - Indicates a problem access the JDBC result set

read

Object read(ResultSet resultSet,
          ResultSetProcessingContext context)
            throws SQLException

Essentially performs the second phase of two-phase loading.

Parameters:

resultSet - The result set being processed

context - The context for the processing

Returns:

The read object

Throws:

SQLException - Indicates a problem access the JDBC result set
