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

Returns:

A new Expression representing a portion or the totality of the given text
