buildExpression

AbstractExpression buildExpression(AbstractExpression parent,
                                   WordParser wordParser,
                                   java.lang.String word,
                                   JPQLQueryBNF queryBNF,

                                   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
