Class DefaultJPQLQueryContext

  • public class DefaultJPQLQueryContext
extends JPQLQueryContext
    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);
