Class ConcatIterator

java.lang.Object
  |
  +--edu.cmu.andrew.icalendar.util.ConcatIterator

All Implemented Interfaces:

CharacterIterator, Cloneable

public final class ConcatIterator

extends Object

implements CharacterIterator

Concatanates several CharacterIterators together to form a larger CharacterIterator. Improvements desired:

• a unit test
• ability to specify a "insert character between list entries" (ie, whitespace so that the words are always broken there)
