Method Detail

setRowMapper

public void setRowMapper(RowMapper<T> rowMapper)

Set a specific RowMapper instance to use for this query.

Since:

4.3.2

setRowMapperClass

public void setRowMapperClass(java.lang.Class<? extends RowMapper> rowMapperClass)

Set a RowMapper class for this query, creating a fresh RowMapper instance per execution.

afterPropertiesSet

public void afterPropertiesSet()

Description copied from class: RdbmsOperation

Ensures compilation if used in a bean factory.

Specified by:

afterPropertiesSet in interface InitializingBean

Overrides:

afterPropertiesSet in class RdbmsOperation

newRowMapper

protected RowMapper<T> newRowMapper(java.lang.Object[] parameters,
                                    java.util.Map<?,?> context)

Description copied from class: SqlQuery

Subclasses must implement this method to extract an object per row, to be returned by the execute method as an aggregated List.

Specified by:

newRowMapper in class SqlQuery<T>

Parameters:

parameters - the parameters to the execute() method, in case subclass is interested; may be null if there were no parameters.

context - contextual information passed to the mapRow callback method. The JDBC operation itself doesn't rely on this parameter, but it can be useful for creating the objects of the result list.
