CharsRef(char[] chars,
int offset,
int length)
Creates a new
CharsRef initialized with the given array, offset and
length |

clone()
Returns a shallow clone of this instance (the underlying characters are
not copied and will be shared by both the returned object and this
object.
|
int |
compareTo(CharsRef other)
Signed int order comparison
|
static CharsRef |
deepCopyOf(CharsRef other)
Creates a new CharsRef that points to a copy of the chars from
other |

Deprecated.
This comparator is only a transition mechanism
