Method Detail

buildExpression

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

                                             boolean tolerant)
Creates the actual AbstractExpression this factory manages.

Specified by:
buildExpression in class AbstractLiteralExpressionFactory
Parameters:
parent - The parent AbstractExpression
wordParser - The text to parse based on the current position of the cursor
word - The current word being parsed
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
