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

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
