org.eclipse.persistence.jpa.jpql.parser.ExpressionVisitor

Packages that use ExpressionVisitor

Package	Description
org.eclipse.persistence.jpa.jpql	This package contains the Hermes features (except the parser itself): semantic and grammatical validations, content assist support, calculating the query result type or the possible type of an input parameter, refactoring tools.
org.eclipse.persistence.jpa.jpql.parser	This is the core of Hermes, this package contains the classes that can parse a JPQL query.
