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.
org.eclipse.persistence.jpa.jpql.tools
org.eclipse.persistence.jpa.jpql.tools.model	The classes defined in this package define the state model API, a state model can be used to manually or programmatically create and edit a JPQL query.
