@Deprecated public final class ByteStreams extends Object
Modifier and Type | Method and Description |
---|---|
static long |
copy(InputStream from,
OutputStream to)
Deprecated.
Copies all bytes from the input stream to the output stream.
|
static InputStream |
limit(InputStream in,
long limit)
Deprecated.
Wraps an input stream, limiting the number of bytes which can be read.
|
static int |
read(InputStream in,
byte[] b,
int off,
int len)
Deprecated.
Reads some bytes from an input stream and stores them into the buffer array
b . |

b
.
This method blocks until len
bytes of input data have been read into the array, or
end of file is detected. The number of bytes read is returned, possibly zero. Does not close
the stream.
A caller can detect EOF if the number of bytes read is less than len
. All subsequent
calls on the same stream will return zero.
If b
is null, a NullPointerException
is thrown. If off
is negative,
or len
is negative, or off+len
is greater than the length of the array b
, then an IndexOutOfBoundsException
is thrown. If len
is zero, then no bytes
are read. Otherwise, the first byte read is stored into element b[off]
, the next one
into b[off+1]
, and so on. The number of bytes read is, at most, equal to len
.
