_yanera Struct Reference

Detailed Description

--------------------------------------------------------------------------- This container holds everything. The idea is this: a pointer to a single yanera_container allocated in the main loop of the program is passed down through the function calls. Every function thus has access to all the stored information; but mostly it is to allow access to the information in _misc and _parameters.

The data model followed here is closely related to the document model of the XML input, that is to say, the first model is a complete description of that model, and additional models only show modifications to that base model. Thus, the XML file is read into models_xml just as they appear in the XML file. Then models_complete is contructed from the models_xml.

Bug:: There's no completeness checking of the complete models, although that should be trivial.

Shared components are stored in component.

Access to paramters is simple, for example, to retrieve the real SLD from a layer with either layer_id "L" or name "NAME" from within a certain model with data_idref "M", one can try the psuedocode here

  yanera_container *y;
  yanera_layer     *l;

First walk down the model list:

  for i=0 to y->number_of_models-1
  {
    if (y->model[i].idref == "M") break;
  }

Now traverse the layer list:

  l = y->model[i].layer;
  while ((l->id != "L") || (l->name != "NAME"))
  {
    l = l->next;
  }

At this point, l now points to desired layer in desired model, and the value of a parameter, rsld for example, can be easily obtained:

  y->parameters.p[l->rsld]
