public class EclipseLinkJPQLQueryContext extends JPQLQueryContext
This context is used to store information related to the JPQL query. It supports the EclipseLink extension over the default JPQL grammar.
If the JPQL query is already parsed, then the context can use it and it needs to be set before setting theIQueryexternalQuery = ...; JPQLQueryContext context = new JPQLQueryContext(DefaultJPQLGrammar.instance()); context.setQuery(query);IQuery:JPQLExpressionjpqlExpression = ...; JPQLQueryContext context = new JPQLQueryContext(DefaultJPQLGrammar.instance()); context.setJPQLExpression(jpqlExpression); context.setQuery(query);- Version:
