org.eclipse.persistence.jpa.jpql.tools.DefaultJPQLQueryContext
public class DefaultJPQLQueryContext
This context is used to store information related to the JPQL query.
IQuery externalQuery = ...;
JPQLQueryContext context = new JPQLQueryContext(DefaultJPQLGrammar.instance());
context.setQuery(query);
If the JPQL query is already parsed, then the context can use it and it needs to be set before
setting the IQuery:
JPQLExpression jpqlExpression = ...;
JPQLQueryContext context = new JPQLQueryContext(DefaultJPQLGrammar.instance());
context.setJPQLExpression(jpqlExpression);
context.setQuery(query);
