| java.io.DataInput |
 Known Indirect Subclasses
|
Defines an interface for classes that are able to read big-endian 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.

| IOException |
|---|
Reads byteCount bytes from this stream and stores them in the byte
array dst starting at offset. If byteCount is zero, then this
method returns without reading any bytes. Otherwise, this method blocks until
byteCount bytes have been read. If insufficient bytes are available,
EOFException is thrown. If an I/O error occurs, IOException is
thrown. When an exception is thrown, some bytes may have been consumed from the stream
and written into the array.
| dst | the byte array into which the data is read. |
|---|---|
| offset | the offset in dst at which to store the bytes. |
| byteCount | the number of bytes to read. |
| EOFException | if the end of the source stream is reached before enough bytes have been read. |
|---|---|
| IndexOutOfBoundsException | if offset < 0 or byteCount < 0, or
offset + byteCount > dst.length. |
| IOException | if a problem occurs while reading from this stream. |
| NullPointerException | if dst is null.

Reads a big-endian 32-bit integer value.
| EOFException | if the end of the input is reached before the read request can be satisfied. |
|---|---|
| IOException | if an I/O error occurs while reading. |
Returns a string containing the next line of text available from this
stream. A line is made of zero or more characters followed by '\n', '\r', "\r\n" or the end of the stream. The string
does not include the newline sequence.

|---|---|
| IOException | if an I/O error occurs while reading. |

Skips count number of bytes. This method will not throw an
EOFException if the end of the input is reached before
count bytes where skipped.
