Class BreakIterator
- Cloneable
This class iterates over text elements such as words, lines, sentences,
and characters. It can only iterate over one of these text elements at
a time. An instance of this class configured for the desired iteration
type is created by calling one of the static factory methods, not
by directly calling a constructor.
The standard iterators created by the factory methods in this
class will be valid upon creation. That is, their methods will
not cause exceptions if called before you call setText().
