findQueryBNF
Description copied from interface:Expression
Retrieves theJPQLQueryBNF
that represents the fragment of thisExpression
that was used when parsing the givenExpression
.- Specified by:
findQueryBNF
in interfaceExpression
- Overrides:
findQueryBNF
in classCompoundExpression
- Parameters:
expression
- TheExpression
that is a descendant of this one- Returns:
- The
JPQLQueryBNF
that was used to parse the given expression
-
getArithmeticSign
Returns the arithmetic sign this expression is actually representing.- Returns:
- The single character value of the arithmetic sign
-
getLeftExpressionQueryBNFId
Description copied from class:CompoundExpression
Returns the unique identifier of theJPQLQueryBNF
for the left expression.- Specified by:
getLeftExpressionQueryBNFId
in classCompoundExpression
- Returns:
- The ID of the BNF used when parsing the expression before the identifier
-
getQueryBNF
Description copied from interface:Expression
Returns the BNF of thisExpression
.- Returns:
- The
JPQLQueryBNF
, which represents the grammar of thisExpression
-
getRightExpressionQueryBNFId
Description copied from class:CompoundExpression
Returns the unique identifier of theJPQLQueryBNF
for the right expression.- Specified by:
getRightExpressionQueryBNFId
in classCompoundExpression
- Returns:
- The ID of the BNF used when parsing the expression after the identifier
-
isParsingComplete
Description copied from class:AbstractExpression
Determines whether the parsing is complete based on what is left in the given text. The text is never empty.- Overrides:
isParsingComplete
in classAbstractExpression
- Parameters:
wordParser
- The text to parse based on the current position of the cursorword
- The word that was retrieved from the given text, which is the first word in the textexpression
- TheExpression
that has already been parsed- Returns:
true
if the text no longer can't be parsed by the current expression;false
if more can be parsed
-
parseIdentifier
Description copied from class:CompoundExpression
Parses the identifier of this expression.- Specified by:
parseIdentifier
in classCompoundExpression
- Parameters:
wordParser
- TheWordParser
containing the text to parse, which starts with the identifier- Returns:
- The identifier for this expression
-
