Java Utililty Methods ByteBuffer Print

void print(ByteBuffer bb)
print

System.out.println("position =" + bb.position() + ", rmaining=" + bb.remaining() + ", limit=" + bb.limit());

String print(ByteBuffer byteBuffer)
print

String text = new String(byteBuffer.array());
return print(text);

void printBuffer(ByteBuffer buffer)
print Buffer

byte[] bytes = new byte[buffer.remaining()];
buffer.get(bytes);
System.out.println(Arrays.toString(bytes));

void printBuffer(ByteBuffer buffer)
Prints the given buffer in hex format from the 0 position to the limit.

for (int i = 0; i < buffer.limit(); i++) {
 System.out.format("%x ", buffer.get(i));

String printBuffer(String msg, ByteBuffer buffer)
Print the contents of the buffer out to the PrintStream in hex and ASCII.

StringBuffer sbuf = new StringBuffer();
int length = buffer.position();
sbuf.append("--------------------------------------------------------\n\n");
sbuf.append(msg).append("\n");
sbuf.append("\n");
sbuf.append("Thread : ").append(Thread.currentThread().getName()).append("\n");
sbuf.append("Total length (ByteBuffer position) : ").append(length).append("\n");
sbuf.append("Byte Buffer capacity : ").append(buffer.capacity()).append("\n\n");

if (data.length == 4) {
 w.append(" int:");
 w.append(Integer.toString(buf.duplicate().getInt()));

String printData(ByteBuffer buf, int offset, int len)
print Data

byte[] tmp = new byte[len];
int pos = buf.position();
buf.position(offset);
buf.get(tmp);
buf.position(pos);
return printData(tmp, len);

String printData(ByteBuffer buffer, int len)
print Data

 if (counter == 16) {
 int charpoint = i - 15;
 for (int a = 0; a < 16; a++) {
...

void printImageContentsSubset(ByteBuffer buf, int w, int h)
Print a small subset of the given image, namely the upper left 20x20.

int lineSize = w * 4;
w = (w > 20) ? 20 : w;
h = (h > 20) ? 20 : h;
IntBuffer ibuf = buf.asIntBuffer();
int nextLine = 0;
for (int y = 0; y < h; y++, nextLine += lineSize) {
 ibuf.position(nextLine);
 for (int x = 0; x < w; x++) {

void println(String string, ByteBuffer buffer)
println

if (buffer == null || !buffer.hasRemaining())
 return;
byte[] bytes = new byte[buffer.remaining()];
buffer.get(bytes);
buffer.flip();
println(string, bytes);
