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 theIQuery
externalQuery = ...; JPQLQueryContext context = new JPQLQueryContext(DefaultJPQLGrammar.instance()); context.setQuery(query);IQuery
:JPQLExpression
jpqlExpression = ...; JPQLQueryContext context = new JPQLQueryContext(DefaultJPQLGrammar.instance()); context.setJPQLExpression(jpqlExpression); context.setQuery(query);- Since:
