Class TimeParser

java.lang.Object
  prefuse.data.parser.DateParser
      prefuse.data.parser.TimeParser

All Implemented Interfaces:

DataParser

public class TimeParser
extends DateParser

DataParser instance that parses Date values as java.util.Time instances, representing a particular time (but no specific date). This class uses a backing DateFormat instance to perform parsing. The DateFormat instance to use can be passed in to the constructor, or by default the DateFormat returned by DateFormat.getTimeInstance(int) with an argument of DateFormat.SHORT is used.
