public final class ByteStreams
Deprecated. use Guava's com.google.common.io.ByteStreams
Provides utility methods for working with byte arrays and I/O streams.
Static Methods
copy(InputStream from, OutputStream to) (deprecated)
public static long copy(InputStream from, OutputStream to)
Copies all bytes from the input stream to the output stream. Does not close or flush either stream.
Parameters | |
---|---|
Name | Description |
from |
InputStream the input stream to read from |
to |
OutputStream the output stream to write to |
Returns | |
---|---|
Type | Description |
long |
the number of bytes copied |
Exceptions | |

limit(InputStream in, long limit) (deprecated)
public static InputStream limit(InputStream in, long limit)
Wraps an input stream, limiting the number of bytes which can be read.
Parameters | |
---|---|
Name | Description |
in |
InputStream the input stream to be wrapped |
limit |
long the maximum number of bytes to be read |
Returns | |
---|---|
Type | Description |
InputStream |
a length-limited InputStream |
read(InputStream in, byte[] b, int off, int len) (deprecated)
public static int read(InputStream in, byte[] b, int off, int len)
Reads some bytes from an input stream and stores them into the buffer array 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
.
Parameters | |
---|---|
Name | Description |
in |
InputStream the input stream to read from |
b |
byte[] the buffer into which the data is read |
off |
int an int specifying the offset into the data |
len |
int an int specifying the number of bytes to read |
Returns | |
---|---|
Type | Description |
int |
the number of bytes read |
Exceptions | |
