Java Utililty Methods ByteBuffer to String

String asStr(ByteBuffer buff)
as Str

return new String(buff.array(), buff.arrayOffset() + buff.position(), buff.limit());

String asString(ByteBuffer buffer, int length)
Returns the contents of a buffer as a string, converting ASCII characters in the buffer, into unicode string characters.

char[] chars = new char[length];
for (int i = 0; i < length; i++) {
 chars[i] = (char) buffer.get(i);
return String.valueOf(chars);

String asString(final ByteBuffer buffer)
as String

final byte[] bytes = new byte[buffer.limit()];
buffer.get(bytes);
return new String(bytes, "US-ASCII");

String asString(Map headers)
as String

if (headers == null) {
 return null;
Iterator<Entry<ByteBuffer, ByteBuffer>> i = headers.entrySet().iterator();
if (!i.hasNext()) {
 return "{}";
StringBuilder sb = new StringBuilder();
