buildExpression
protected AbstractExpression buildExpression(AbstractExpression parent, WordParser wordParser, java.lang.String word, JPQLQueryBNF queryBNF, AbstractExpression expression, boolean tolerant)
Creates a newExpression
.- Specified by:
buildExpression
in classExpressionFactory
- Parameters:
parent
- The parentAbstractExpression
wordParser
- 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
AbstractExpression
representing the portion or the totality of the text held byWordParser
starting at the cursor position
