This class defines a generic API, on which the interaction protocol between a dynamic view server and its application components is based. Any representation object types that are referenced in a view specification must be implemented by a type that derives from this class. An instance of this class is configured by a representation object model specific to a representation.

A set of editing methods lets you create and update your representation objects. To actually update representation objects, you must redefine those methods. Symmetrically, this class defines a set of callback methods that should be invoked whenever a representation object is directly modified by an application component. These methods are responsible for sending modifications to the server.

The macros used in the C++ version of Rogue Wave Server to specify mappings (ILS_RP_ATTR_XXX, ILS_RP_DEFAULT_ATTR_XXX, etc.) are replaced by static methods with the same meaning. Typically, these "macros" are put into the static initializer of the corresponding representation class. You can also use the functions of the Mapping class to specify mappings.

public class RowRp
      : RpObject {
    ....
  public void SetParent(TableRp p) {
    ...
  }
  public void SetValue(int i, String val) {
    ...
  }
  public void SetValue(int i, int val) {
    ...
  }

  static RpRow() {
     ILS_RP_ATTR_REF("RowRp", "parent", "SetParent", "TableRp");
     ILS_RP_INDEXED_ATTR_STRING("RowRp", "column", "SetValue");
     ILS_RP_INDEXED_ATTR_INT("RowRp",    "column", "SetValue");
  }
};
