void |
accept(StateObjectVisitor visitor)
Visits this
StateObject by the given visitor . |
EmptyCollectionComparisonExpressionStateObject |
addNot()
Makes sure the
NOT identifier is specified. |
EmptyCollectionComparisonExpression |
getExpression()
Returns the actual parsed object if this
StateObject representation of the JPQL query
was created by parsing an existing JPQL query. |
CollectionValuedPathExpressionStateObject |
getStateObject()
Returns the
CollectionValuedPathExpressionStateObject representing the collection-
valued path expression. |
boolean |
hasNot()
Determines whether the
NOT identifier is used or not. |
boolean |
isEquivalent(StateObject stateObject)
Determines whether the given
StateObject is equivalent to this one, i.e. |
void |
removeNot()
Makes sure the
NOT identifier is not specified. |
void |
setExpression(EmptyCollectionComparisonExpression 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 . |
void |
setNot(boolean not)
Sets whether the
NOT identifier should be part of the expression or not. |
void |
toggleNot()
Changes the visibility state of the
NOT identifier. |
