STATE_OBJECT_PROPERTY
Notifies the state object property has changed. |
Constructor Summary | |
---|---|
NotExpressionStateObject(StateObject parent)
Creates a new NotExpressionStateObject . |
|
NotExpressionStateObject(StateObject parent,
StateObject stateObject)
Creates a new NotExpressionStateObject . |
|
NotExpressionStateObject(StateObject parent,
java.lang.String jpqlFragment)
Creates a new NotExpressionStateObject . |
Method Summary | |
---|---|
void |
accept(StateObjectVisitor visitor)
Visits this StateObject by the given visitor . |
protected void |
addChildren(java.util.List<StateObject> children)
Adds the children of this StateObject to the given list. |
NotExpression |
getExpression()
Returns the actual parsed object if this StateObject representation of the JPQL query
was created by parsing an existing JPQL query. |
StateObject |
getStateObject()
Returns the StateObject representing the negated expression. |
boolean |
hasStateObject()
Determines whether the StateObject representing the encapsulated expression is
present or not. |
boolean |
isEquivalent(StateObject stateObject)
Determines whether the given StateObject is equivalent to this one, i.e. the
information of both StateObject is the same. |
void |
parse(java.lang.String jpqlFragment)
Parses the given JPQL fragment, which represents the negated expression, and creates the StateObject . |
void |
setExpression(NotExpression 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 |
setStateObject(StateObject stateObject)
Sets the given StateObject as the new negated expression. |
protected void |
toTextInternal(java.lang.Appendable writer)
Prints out a string representation of this StateObject , which should not be used to
define a true string representation of a JPQL query but should be used for
debugging purposes. |
