oracle.toplink.essentials.internal.parsing.NodeFactoryImpl

INTERNAL

Purpose: Implements a node factory used by the EJBQLParser class.

Responsibilities:

Create EJBQLParseTree instances for EJBQL SELECT-, UPDATE- and DELETE statements (see methods newSelectStatement, newUpdateStatement and newDeleteStatement).
Any new method returns an instance of the appropriate Node subclass.
The relationship to the child nodes passed as arguments are automatically initialized.
Note, this implementation has a state managing the parse tree context and a list of parameter names for the current parse tree. This state needs to be initilized before the same node factory implementation instacne may be used to create a second parse tree (see methods initContext and initParameters).
The implementation automatically adds the list of parameters to the created parse tree.
The implementation automatically sets the parse tree context for any created major node.

        throws EJBQLException {
        try {
            EJBQLParser parser = EJBQLParserBuilder.buildParser(queryText);
            parser.setQueryName(queryName);
            parser.setQueryText(queryText);
            parser.setNodeFactory(new NodeFactoryImpl(parser.getQueryInfo()));
            return parser;
        } catch (Exception ex) {
            throw EJBQLException.generalParsingException(queryText, ex);
        }
    }
