ArithmeticFactor. |
| Modifier and Type | Method and Description |
|---|---|
void |
accept(ExpressionVisitor visitor)
Visits this
Expression by the given visitor. |
void |
acceptChildren(ExpressionVisitor visitor)
Visits the children of this
Expression. |
protected void |
addChildrenTo(Collection<Expression> children)
Adds the children of this
AbstractExpression to the given collection. |
protected void |
addOrderedChildrenTo(List<Expression> children)
Adds the children of this
AbstractExpression to the given list. |
JPQLQueryBNF |
findQueryBNF(Expression expression)
Retrieves the
JPQLQueryBNF that represents the fragment of this Expression
that was used when parsing the given Expression. |
Expression |
getExpression()
Returns the
Expression representing the arithmetic primary. |
JPQLQueryBNF |
getQueryBNF()
Returns the BNF of this
Expression. |
protected boolean |
handleAggregate(JPQLQueryBNF queryBNF)
Determines whether the given
JPQLQueryBNF handles aggregate expressions. |
boolean |
hasExpression()
Determines whether the arithmetic primary was parsed.
|
boolean |
hasSpaceAfterArithmeticOperator()
Determines whether a whitespace was parsed after the arithmetic operator.
|
boolean |
isNegative()
Determines if the arithmetic primary is prepended with the minus sign.
|
protected boolean |
isParsingComplete(WordParser wordParser,
String word,
Expression expression)
Determines whether the parsing is complete based on what is left in the given text.
|
boolean |
isPositive()
Determines if the arithmetic primary is prepended with the plus sign.
|
protected void |
parse(WordParser wordParser,
boolean tolerant)
Parses the query by starting at the current position, which is part of the given
WordParser. |
protected void |
toParsedText(StringBuilder writer,
boolean actual)
Generates a string representation of this
Expression, including its children,
if it has any. |

ArithmeticFactor.parent - The parent of this expressionarithmeticFactor - The arithmetic factor, which is either '+' or '-'public void accept(ExpressionVisitor visitor)
Expression by the given visitor.visitor - The ExpressionVisitor to visit this objectpublic void acceptChildren(ExpressionVisitor visitor)
Expression. This method can be used to optimize traversing
the children since a new list is not created every time Expression.children() is called.
This does not traverse the Expression sub-hierarchy, use a subclass of
AbstractTraverseChildrenVisitor in order to traverse the entire sub-hierarchy.

i.e. include any "virtual" whitespace (such as ending whitespace) and the actual case of the
