.- Parameters:
visitor
- TheExpressionVisitor

isParsingComplete
Description copied from class:AbstractExpression
Determines whether the parsing is complete based on what is left in the given text. The text is never empty.- Overrides:
isParsingComplete
in classArithmeticExpression
- Parameters:
wordParser
- The text to parse based on the current position of the cursorword
- The word that was retrieved from the given text, which is the first word in the textexpression
- TheExpression
that has already been parsed- Returns:
true
if the text no longer can't be parsed by the current expression;false
if more can be parsed
