Class LineTokenizer

java.lang.Object

org.argeo.slc.diff.LineTokenizer

public class LineTokenizer
extends java.lang.Object

Parses a string as a vector of strings according to a separator, dealing properly with missing values. This is intended to be used instead of the standard StringTokenizer, which does not deal well with empty values. Contrary to the StringTokenizer the provided String is parsed in the constructor and the values stored as a property. This should therefore not be used to parse long strings. No reference to the argument passed in constructor is kept.
