buildExpression
protected final AbstractExpression buildExpression(AbstractExpression parent, WordParser wordParser, java.lang.String word, JPQLQueryBNF queryBNF, AbstractExpression expression, boolean tolerant)
Creates a newExpression.- Specified by:
buildExpressionin classExpressionFactory- Parameters:
parent- The parentAbstractExpressionwordParser- The text to parse based on the current position of the cursorword- The current word being parsedqueryBNF- The BNF grammar that was used to identifier this factory to be capable to parse a portion of the queryexpression- 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
AbstractExpressionrepresenting the portion or the totality of the text held byWordParserstarting at the cursor position
