public final class EclipseLinkJPQLGrammar2_0 extends AbstractJPQLGrammar
This JPQLGrammar
provides support for parsing JPQL queries defined in JSR-337 - Java Persistence 2.0. EclipseLink 2.0
does not add any additional support.
in_expression ::= in_expression_expression [NOT] IN { ( in_item {, in_item}* ) | (subquery) | collection_valued_input_parameter }
in_expression_expression ::= { state_field_path_expression | type_discriminator |
single_valued_input_parameter | identification_variable }
Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
