Class ArithmeticExpressionFactory
java.lang.Object
org.eclipse.persistence.jpa.internal.jpql.parser.ExpressionFactory
org.eclipse.persistence.jpa.internal.jpql.parser.ArithmeticExpressionFactory
- All Implemented Interfaces:
- java.lang.Comparable<ExpressionFactory>
-
final class ArithmeticExpressionFactory
- extends ExpressionFactory
This ExpressionFactory
creates a new expression when the portion of the query to parse starts with an arithmetic identifier. It is possible the expression to parse is also a NumericLiteral
or an ArithmeticFactor
.

visitor
private ArithmeticExpressionFactory.ArithmeticExpressionVisitor visitor
- This
ArithmeticExpressionFactory.ArithmeticExpressionVisitor
is used to check if the Expression
passed to this factory is an AdditionExpression
or SubtractionExpression
.
ID
static final java.lang.String ID
- The unique identifier of this
ArithmeticExpressionFactory
.

- Constant Field Values
ArithmeticExpressionFactory
ArithmeticExpressionFactory()
- Creates a new
AbstractArithmeticExpressionFactory
.
- Parameters:
id
- The unique identifier of this ExpressionFactory
identifier
- The JPQL identifier handled by this factory
buildExpression
private CompoundExpression buildExpression(AbstractExpression parent,
char character)
- Creates the
Expression
this factory for which it is responsible.
-
- Parameters:
parent
- The parent of the new Expression
character
-
- Returns:
- A new
CompoundExpression
buildExpression
final AbstractExpression buildExpression(AbstractExpression parent,
WordParser wordParser,
java.lang.String word,
JPQLQueryBNF queryBNF,
AbstractExpression expression,
boolean tolerant)
- Creates a new
Expression
.
-
- Specified by:
buildExpression
in class ExpressionFactory
-
- Parameters:
parent
- The parent expression
wordParser
- The text to parse based on the current position of the cursor
word
- The current word to parse
queryBNF
- The BNF grammar that was used to identifier this factory to be capable to parse a portion of the query
expression
- During the parsing, it is possible the first part of an expression was parsed which needs to be used as a sub-expression of the newly created expression
- Returns:
- A new
Expression
representing a portion or the totality of the given text
