Description

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

Method

InputStreaminputStream(ByteBuffer bytes)
input Stream 
final ByteBuffer copy = bytes.duplicate();
return new InputStream() {
    public int read() throws IOException {
        if (!copy.hasRemaining())
            return -1;
        return copy.get() & 0xFF;
    @Override
...
ByteBufferinputStreamToByteBuffer(InputStream input)
Loads an input stream fully keeping the whole file in memory. 
ByteArrayOutputStream bas = new ByteArrayOutputStream(1000000); 
byte[] buf = new byte[1024];
int n;
while ((n = input.read(buf)) != -1)
    bas.write(buf, 0, n);
input.close();
buf = bas.toByteArray();
ByteBuffer byteBuffer = ByteBuffer.wrap(buf);
...
ByteBufferinputStreamToByteBuffer(InputStream is)
input Stream To Byte Buffer 
final int PAGE_SIZE = 4096;
final ArrayList<byte[]> pages = new ArrayList<byte[]>();
for (;;) {
    byte[] page = new byte[PAGE_SIZE];
    int pagePos = 0;
    int read;
    do {
        read = is.read(page, pagePos, PAGE_SIZE - pagePos);
...
InputStreammakeInputStream(final ByteBuffer buffer)
make Input Stream 
return new InputStream() {
    @Override
    public synchronized int read() throws IOException {
        return buffer.hasRemaining() ? buffer.get() : -1;
    @Override
    public int read(byte[] b, int off, int len) throws IOException {
        final int rv = Math.min(len, buffer.remaining());
...
voidmoveBufferToStream(OutputStream out, ByteBuffer in, int length)
Copy the data to the output stream and update position in buffer. 
copyBufferToStream(out, in, in.position(), length);
skip(in, length);
voidoutputBuffer(ByteBuffer buffer)
output Buffer 
try {
    byte[] rawBytes = new byte[buffer.capacity()];
    buffer.get(rawBytes);
    File outputFile = new File(String.format("owf_%04d.bin", frame));
    OutputStream streamOut = new BufferedOutputStream(new FileOutputStream(outputFile));
    streamOut.write(rawBytes);
    streamOut.close();
} catch (Throwable th) {
...
voidput(ByteBuffer bb, byte[] bytes, int from)
The missing method on a ByteBuffer - allows copying of multiple bytes into the buffer. 
int counter = 0;
for (byte b : bytes) {
    bb.put(from + counter, b);
    ++counter;
ByteBufferput(ByteBuffer bb, String s)
put 
bb = expand(bb, s.length());
for (int i = 0; i < s.length(); i++) {
    bb.put(i, (byte) s.charAt(i));
return bb;
ByteBufferput(ByteBuffer bbuf, byte[] post)
put 
ByteBuffer b = bbuf;
int postLen = post.length;
if (postLen == 0)
    return b;
if (postLen > bbuf.remaining()) {
    int esize = DEFAULT_ENHANCE_SIZE + postLen - bbuf.remaining();
    b = enhance(bbuf, esize);
b.put(post);
return b;
voidput(ByteBuffer buf, String s, String charsetName)
Puts a String 's bytes in the character set starting at the ByteBuffer 's current position. 
try {
    buf.put(s.getBytes(charsetName));
} catch (UnsupportedEncodingException e) {
    throw new IllegalArgumentException(e);
