This context is used to store information related to the JPQL query. It supports the EclipseLink extension over the default JPQL grammar. 
 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);
