Method Detail

buildExpression

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