public class NotExpressionStateObject
expression ::= NOT conditional_primary
NotExpression| Field Summary | |
|---|---|
static java.lang.String |
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. |

will be parsed and converted into a StateObject

public void accept(StateObjectVisitor visitor)
StateObject by the given visitor.
visitor - The visitor to visit this objectprotected void addChildren(java.util.List<StateObject> children)
StateObject to the given list.
addChildren in class AbstractStateObjectchildren - The list used to store the childrenpublic NotExpression getExpression()
StateObject representation of the JPQL query
was created by parsing an existing JPQL query.
getExpression in interface StateObjectgetExpression in class AbstractStateObjectStateObject
or null when the JPQL query is manually created (i.e. not from a string)public StateObject getStateObject()
StateObject representing the negated expression.
StateObject representing the negated expressionpublic boolean hasStateObject()
StateObject representing the encapsulated expression is
present or not.
true if the encapsulated StateObject is not null;
false otherwisepublic boolean isEquivalent(StateObject stateObject)
StateObject is equivalent to this one, i.e. the
information of both StateObject is the same.
isEquivalent in interface StateObjectisEquivalent in class AbstractStateObjectstateObject - The StateObject to compare its content to this one
true if both object are equivalent; false otherwisepublic void parse(java.lang.String jpqlFragment)
StateObject.
jpqlFragment - The portion of the query representing the negated expressionpublic void setExpression(NotExpression expression)
parsed object object, which should only be
done when this object is instantiated during the conversion of a parsed JPQL query into
StateObjects.
expression - The parsed object representing a NOT
expressionpublic void setStateObject(StateObject stateObject)
StateObject as the new negated expression.
stateObject - The StateObject representing the negated expression
protected void toTextInternal(java.lang.Appendable writer)
throws java.io.IOException
StateObject, which should not be used to
define a true string representation of a JPQL query but should be used for
debugging purposes.
toTextInternal in class AbstractStateObjectwriter - The writer used to print out the string representation
java.io.IOException - This should never happens, it is only required because Appendable
is used instead of any concrete class
