    228228Please note that the {{{setMapInMaps}}} function is able to create or update an existing {{{map}}}. Indeed, if a {{{map}}} called « value » allready exists, then its value will be updated automatically.
     229
     230Even if you will mainly use {{{map}}} from {{{maps}}} during this workshop, you can also add or update values in a {{{map}}} directly using the {{{addToMap}}} function defined in {{{zoo-kernel/service.h}}}. The {{{addToMap}}} function take three paramters :
     231
     232 * {{{m}}} : a {{{map}}} pointer you want to update,
     233 * {{{n}}} : the name of the {{{map}}} you want to add or update the value,
     234 * {{{v}}} : the value you want to set in this {{{map}}}.

    230236This datatype is really important cause it is used in every C based ZOO Services. It is also the same representation used in other languages but using their respectives datatypes. For Example in Python, the dictionaries datatype is used, so manipulation is much easier.
