| Constructor and Description |
|---|
ArithmeticFactorStateObject(StateObject parent)
Creates a new
ArithmeticFactorStateObject. |
ArithmeticFactorStateObject(StateObject parent,
boolean plusSign,
StateObject stateObject)
Creates a new
ArithmeticFactorStateObject. |
| Modifier and Type | Method and Description |
|---|---|
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. |
void |
addMinus()
Makes sure the
- sign is used. |
void |
addPlus()
Makes sure the
+ sign is used. |
java.lang.String |
getArithmeticSign()
Returns the arithmetic sign this expression is actually representing.
|
ArithmeticFactor |
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 that represents the arithmetic primary expression. |
boolean |
hasMinusSign()
Determines whether the arithmetic sign is the minus sign.
|
boolean |
hasPlusSign()
Determines whether the arithmetic sign is the plus sign.
|
boolean |
hasStateObject()
Determines whether an
StateObject representing the arithmetic primary expression
exists. |
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 to become the new arithmetic primary.
|
void |
setArithmeticSign(boolean plusSign)
Sets the arithmetic sign this expression is actually representing.
|
void |
setExpression(ArithmeticFactor 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)
Returns the
StateObject that represents the arithmetic primary expression. |
void |
toggleArithmeticSign()
Toggles the arithmetic sign, plus becomes minus and vice versa.
|
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. |
