Description

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

Method

byte[]toBytes(ByteBuffer buffer)
to Bytes 
if (buffer == null)
    return null;
if (buffer.hasArray()) {
    return Arrays.copyOfRange(buffer.array(), buffer.position() + buffer.arrayOffset(),
            buffer.limit() + buffer.arrayOffset());
} else {
    byte[] data = new byte[buffer.remaining()];
    buffer.duplicate().get(data);
...
byte[]toBytes(ByteBuffer buffer, int offset, int length)
Copy the given number of bytes from specified offset into a new byte[] 
byte[] output = new byte[length];
for (int i = 0; i < length; i++) {
    output[i] = buffer.get(offset + i);
return output;
byte[]toBytes(ByteBuffer buffer, int startPosition)
Copy the bytes from position to limit into a new byte[] of the exact length and sets the position and limit back to their original values (though not thread safe). 
int originalPosition = buffer.position();
byte[] output = new byte[buffer.limit() - startPosition];
buffer.position(startPosition);
buffer.get(output);
buffer.position(originalPosition);
return output;
byte[]toBytes(ByteBuffer value)
Convert a ByteBuffer to a byte[] ByteBuffer is reset to its original state. 
byte[] result = null;
if (value != null && value.remaining() > 0) {
    result = new byte[value.remaining()];
    value.mark();
    value.get(result);
    value.reset();
return result;
...
byte[]toBytes(final ByteBuffer bb)
to Bytes 
return toBytes(bb, bb.limit());
