QueryExpression describes components that can evaluate an XML document based on a specific query language. An example of such a query language is XPath 1.0. Evaluation of a query expression on an XML document should result in a set of DOM Nodes no matter what language is used. @author Dan Jemiolo (danj)

Expression for a query in language-independent form.
org.exolab.castor.persist.spi.QueryExpression
Defines the interface for a query expression. The query expression object is used to construct queries including parameters, conditions and joins, and generates the SQL statement for the underlying database.
A query experession object is created for each unique query, populated with the query parameters and the SQL statement is obtained from it at the proper time.
A query expression is generated from {@link PersistenceFactory}, see this interface for information on how to configure it. The operators defined in this interface are part of SQL 92 and the supported OQL syntax and are expected to be supported by all query expressions. @author Assaf Arkin @version $Revision: 7121 $ $Date: 2005-03-05 06:42:06 -0700 (Sat, 05 Mar 2005) $
