                                             String word,

                                             boolean tolerant)

Description copied from class: ExpressionFactory

Creates a new Expression.

Specified by:

buildExpression in class ExpressionFactory

Parameters:

parent - The parent AbstractExpression

wordParser - The text to parse based on the current position of the cursor

word - The current word being parsed

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 AbstractExpression representing the portion or the totality of the text held by WordParser starting at the cursor position
