org.eclipse.persistence.jpa.jpql.tools.JPQLQueryContext

org.eclipse.persistence.jpa.jpql.tools.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);
