Description

The list of methods to do ByteBuffer Put are organized into topic(s).

Method

voidbufToStream(ByteBuffer b, OutputStream out)
buf To Stream 
int i = b.position();
while (i < b.limit()) {
    out.write(b.get(i++));
InputStreambyteBufferToInputStream(final ByteBuffer byteBuffer)
Produce an InputStream that is able to read from a ByteBuffer . 
return new InputStream() {
    final ByteBuffer buf = byteBuffer;
    @Override
    public int read() throws IOException {
        if (!buf.hasRemaining()) {
            return -1;
        return buf.get() & 0xFF;
...
voidbyteBufferToOutputStream(ByteBuffer in, OutputStream out)
Reads the full contents of a ByteBuffer and writes them to an OutputStream. 
final int BUF_SIZE = 8192;
if (in.hasArray()) {
    out.write(in.array(), in.arrayOffset() + in.position(), in.remaining());
} else {
    final byte[] b = new byte[Math.min(in.remaining(), BUF_SIZE)];
    while (in.remaining() > 0) {
        int bytesToRead = Math.min(in.remaining(), BUF_SIZE);
        in.get(b, 0, bytesToRead);
...
voidcheckReadSpace(FileInputStream aStream, ByteBuffer aBuf)
check Read Space 
if (aBuf.remaining() < 8) {
    aBuf.flip();
    aStream.getChannel().read(aBuf);
    aBuf.flip();
longcomputeSize(ByteBuffer[] buffers)
compute Size 
long size = 0;
for (ByteBuffer byteBuffer : buffers) {
    size += byteBuffer.remaining();
return size;
voidconvert(Object lock, CharsetEncoder encoder, ByteBuffer bytes, CharBuffer chars, OutputStream out)
convert 
synchronized (lock) {
    checkEncoder(encoder);
    CoderResult result = encoder.encode(chars, bytes, true);
    while (true) {
        if (result.isError()) {
            throw new IOException(result.toString());
        } else if (result.isOverflow()) {
            flushOutputStreamWriter(out, bytes, encoder, lock);
...
StringdeserializeString(ByteBuffer inputBuffer, Charset charset)
Deserializes a string from byte buffer 
int size = inputBuffer.getInt();
byte[] value = new byte[size];
inputBuffer.get(value);
return new String(value, charset);
StringextractString(ByteArrayOutputStream byteBuffer)
extract String 
String string = new String(byteBuffer.toByteArray(), CHARSET);
byteBuffer.reset();
return string;
voidflushOutputStreamWriter(OutputStream out, ByteBuffer bytes, CharsetEncoder encoder, Object lock)
flush Output Stream Writer 
synchronized (lock) {
    checkEncoder(encoder);
    int position;
    if ((position = bytes.position()) > 0) {
        bytes.flip();
        out.write(bytes.array(), 0, position);
        bytes.clear();
    out.flush();
byte[][]getZeroTerminatedStringBytesArray(ByteBuffer inputBuffer)
get Zero Terminated String Bytes Array 
ArrayList<byte[]> array = new ArrayList<>();
while (inputBuffer.remaining() > 0) {
    array.add(getZeroTerminatedStringBytes(inputBuffer));
return array.toArray(new byte[array.size()][]);
