Method Summary

Modifier and TypeMethod and Description
public void
append(List<ByteBuffer> lists)

Append a list of ByteBuffers to this stream.

public List<ByteBuffer>
getBufferList()

Returns all data written and resets the stream to be empty.

public void
prepend(List<ByteBuffer> lists)

Prepend a list of ByteBuffers to this stream.

public void
write(byte[]
the data.
b
,
int
the start offset in the data.
off
,

Overrides java.io.OutputStream.write.

Writes len bytes from the specified byte array starting at offset off to this output stream.

public void write(int b)

Implements abstract java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

Parameters
b:int

the byte.

public void write(byte[] b, int off, int len)

Overrides java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes len bytes from the specified byte array starting at offset off to this output stream. The general contract for write(b, off, len) is that some of the bytes in the array b are written to the output stream in order; element b[off] is the first byte written and b[off+len-1] is the last byte written by this operation.

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.

Parameters
b:byte[]

the data.

off:int

the start offset in the data.

len:int

the number of bytes to write.

Annotations

public void writeBuffer(ByteBuffer buffer) throws IOException

Add a buffer to the output without copying, if possible.
