public class RepeatableRule
extends ChoiceRule

name: [[rule]](option) Repeatable rules are rules that are repeated sequencially one after the other in some form option: ? means either the rule does not parse or it does once and only once, i.e. that it is made optional means either the rule does not parse or it does any number of times + means the rule must parse at least once, and can parse any number of times after

Constructor Summary

Constructors

Constructor	Description
RepeatableRule(java.lang.String aName, int aMin, int aMax)
RepeatableRule(java.lang.String name, int min, int max, ChoiceRule rule)	Takes one rule and the minimum number of repeats as well as the maximum

Method Summary

Modifier and Type	Method	Description
void	delete()
java.lang.String	getFirstValue()	The size of a repeatable rule can be 0 or 1 and, therefore can have the value of either "" or the value of it's one and only rule
int	getMax()	the maximum number of times the subrule should be considered to be able to parse(a max of 1 will not repeat more than once)
int	getMin()	the minimum number of times the subrule can be parsed for this rule to be successful
boolean	isOptional()	returns true if optional, i.e.
boolean	optimizeCondition()	For optimization, this object will be removed if it has no sub rules.
int	parse(Token token, int from, int stop, java.lang.String input, ParserDataPackage data)	Tries to parse the subrule min<=times<=max.
boolean	setMax(int aMax)
boolean	setMin(int aMin)
java.lang.StringBuilder	toDeclareString(java.lang.StringBuilder builder)
java.lang.String	toString()
