Class TokenIterator

java.lang.Object

org.graalvm.shadowed.com.ibm.icu.impl.data.TokenIterator

public class TokenIterator
extends Object

An iterator class that returns successive string tokens from some source. String tokens are, in general, separated by Pattern_White_Space in the source test. Furthermore, they may be delimited by either single or double quotes (opening and closing quotes must match). Escapes are processed using standard ICU unescaping.
