no.digipost.jdbc

Class AttributeMapper<R>

java.lang.Object

no.digipost.jdbc.AttributeMapper<R>

Type Parameters:

R - The type of the Attribute and the result yielded from the ColumnMapper

All Implemented Interfaces:

RowMapper<R>

public final class AttributeMapper<R>
extends Object
implements RowMapper<R>

An attribute mapper associates a ColumnMapper with an Attribute, and is used internally by an AttributesRowMapper to produce an AttributesMap where the values can be accessed in a type-safe manner.

An AttributeMapper is constructed from an existing ColumnMapper by calling .forColumn(..).

Instances may be directly given to a constructor of an AttributesRowMapper, but can also be used as a standalone RowMapper.
