Class RemoteSearcher

java.lang.Object
  org.dlese.dpc.serviceclients.remotesearch.RemoteSearcher

public class RemoteSearcher
extends Object

RemoteSearcher plays a role anaogous to SimpleLuceneIndex in the DDS, only it performs searches for records using a DDS Web Service (version 1.0). RemoteSearcher employs the WebService client to do the actual search (via the urlCheck method (so this class can be thought of as a wrapper for the urlCheck Service).

A use case of RemoteSearcher follows:

1. the user submits a query, which at this time is in the form of a URL (including wild cards)
2. the query is given to searchDocs(java.lang.String), which in turn calls the UrlCheck method of the WebServiceClient, and then
3. the result Document is parsed into an array of RemoteResultDoc
