| java.io.DataInput |
 Known Indirect Subclasses
|
Defines an interface for classes that are able to read typed data from some
source. Typically, this data has been written by a class which implements
DataOutput. Types that can be read include byte, 16-bit short, 32-bit
int, 32-bit float, 64-bit long, 64-bit double, byte strings, and MUTF-8
strings.
When encoding strings as UTF, implementations of DataInput and
DataOutput use a slightly modified form of UTF-8, hereafter referred
to as MUTF-8. This form is identical to standard UTF-8, except:
U+10000 …
U+10ffff are encoded as a surrogate pair, each of which is
represented as a three-byte encoded value.U+0000 is encoded in two-byte form.Please refer to The Unicode Standard for further information about character encoding. MUTF-8 is actually closer to the (relatively less well-known) encoding CESU-8 than to UTF-8 per se.
