The BaleWeavable Interface and Bale Class

  In the initial design of the Haystack data model we have made the decision to include an interface for nodes that represent collections. The only obvious use for this Straw class (aside from the implicit typing information) is the ability to override certain Straw functions to provide ordering. For example, in Haystack, when a query is invoked a bale.QueryResult object can be generated pointing at the Straws that satisfy the query. What we note, however, is that query results are usually ordered based on some relevance metric. In invoking the getAllForwardObjects() for the bale.QueryResult object, we want the ordering maintained. This is achieved by overriding the getAllForwardObjects() to order the data based on some other information (i.e. a list of results and scores).
