sqlmap - set a map to a parameterclass in iBatis -


what's difference between setting map , setting object parameterclass in ibatis?

means,

<update id="update" parameterclass="map">     update city      set province_id = #province_id#     id = #id#  </update>

and

<update id="update" parameterclass="city">     update city      set province_id = #province_id#     id = #id#  </update>

?

i not find difference when tested both.

i want set "map", scared ...

"map" in parameterclass="map" alias "java.util.map". don't think because city class implements map interface?
