Class RepN

java.lang.Object

io.parsingdata.metal.token.Token

io.parsingdata.metal.token.RepN

public class RepN
extends Token

A Token that specifies a bounded repetition of a token.

A RepN consists of a token (a Token) and an n (a ValueExpression). First n is evaluated. Parsing fails if it does not evaluate to a single value. The token is then parsed for an amount of times equal to the evaluated value of n. RepN succeeds if this succeeds.
