Class Query

java.lang.Object
  org.outerj.daisy.query.model.Query

public class Query
extends java.lang.Object

Describes a query. Obtained from the QueryFactory.

A query contains the following parts:

• a select part (a list of identifiers). Always present.
• a where clause: a query on 'structured' data (metadata etc.). This part is optional if a fulltext query (see below) is specified, otherwise it is always present.
• a fulltext query. Optional. If both a fulltext query and a 'where clause' are specified, the results of both should be AND'ed together. In other words, the where clause' purpose is to further limit the results from the fulltext query.
• order by clause. Optional.

Once a query has been obtained from the QueryFactory, it should be prepared by calling prepare(org.outerj.daisy.query.QueryContext).

This class also has methods to generate SQL for performing the 'where clause'.
