Factory method for creating an appropriate Offer Iterator based on the presence of the Register Interface.
|
private |
Perform and pass on a query over a set of links. Merge the results of the federated queries into a single set of results suitable for returning to the user.
|
private |
This method takes the list of ordered offers and places a number of them in the sequence of returned offers and the rest into thr iterator. In addition, fill_receptacles uses the TAO_Property_Filter to ensure the returned offers contain the properties specified in the desired_props in parameter.
|
private |
If a starting_trader policy was specfied, foward the query to the next link in the sequence.
|
private |
Traverse the type hierarchy to pull the matching offers from all subtypes of the root type.
|
private |
Check if offers of a type fit the constraints and order them according to the preferences submitted.

Merge the results from a federated query into the collected results.

virtual |
|
private |
Assemble a sequence of links that the federate_query method should follow. Use the starting_trader policy, if one's provided, otherwise use the Link interface to determine which of the registered links should be followed in this query.
