Class ISO19115RequestFactory

java.lang.Object
  org.deegree_impl.clients.wcasclient.control.ISO19115RequestFactory

public class ISO19115RequestFactory

extends java.lang.Object

class for creating a get GetRecord Request against a catalog based on OGC Stateless Web Service Catalog Profil and GDI NRW catalog specifications to access data metadata (ISO 19115).

The only public method of the class receives a 'model' represented by a HashMap that contains the request parameters as name-vailue-pairs. The names corresponds to the formular-field-names. For common this will be the fields of a HTML-form but it can be any other form (e.g. swing-application)
