public final class CollectionExpressionStateObject extends AbstractStateObject
StateObject
is a temporary object used to store a list of StateObjects
. Those objects are not parented. StateObjectVisitor
is not aware of this
object either, to visit it, the visitor will be notified via reflection, see AbstractStateObject.acceptUnknownVisitor(StateObjectVisitor)

Visits this
StateObject by the given visitor . |

getExpression()
Returns the actual parsed object if this
StateObject representation of the JPQL query
was created by parsing an existing JPQL query. |

isEquivalent(StateObject stateObject)
Determines whether the given
StateObject is equivalent to this one, i.e. |
void |
setExpression(CollectionExpression expression)
Keeps a reference of the
parsed object object, which should only be
done when this object is instantiated during the conversion of a parsed JPQL query into
StateObjects . |
