Method

StringasStr(ByteBuffer buff)
as Str 
return new String(buff.array(), buff.arrayOffset() + buff.position(), buff.limit());
StringasString(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);
StringasString(final ByteBuffer buffer)
as String 
final byte[] bytes = new byte[buffer.limit()];
buffer.get(bytes);
return new String(bytes, "US-ASCII");
StringasString(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();
...
StringbbToString(ByteBuffer bb)
bb To String 
return new String(bbToArray(bb));
Stringbuffer2String(ByteBuffer buff, String charsetName)
buffer String

StringbufferToString(ByteBuffer buf)
buffer To String 
try {
    boolean isString = true;
    byte[] arr = buf.array();
    for (int i = 0; i < buf.remaining(); i++) {
        byte c = arr[i];
