Constructor Details

MultiplicationExpression

public MultiplicationExpression(AbstractExpression parent)

Creates a new MultiplicationExpression.

Parameters:

parent - The parent of this expression

Method Details

accept

public void accept(ExpressionVisitor visitor)

Description copied from interface: Expression

Visits this Expression by the given visitor.

Parameters:

visitor - The ExpressionVisitor to visit this object

isParsingComplete

protected boolean isParsingComplete(WordParser wordParser,
 String word,
 Expression expression)

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 class ArithmeticExpression

Parameters:

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

word - The word that was retrieved from the given text, which is the first word in the text

expression - The Expression 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
