Description

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

Method

StringgetString(ByteBuffer buf, Charset encoding)
Converts all remaining bytes in the buffer a String using the specified encoding. 
return getString(buf, 0, buf.remaining(), encoding);
StringgetString(ByteBuffer buf, int length, String charsetName)
This is a relative get String method for ByteBuffer because it doesn't have one (but should!). 
try {
    return new String(getBytes(buf, length), charsetName);
} catch (UnsupportedEncodingException e) {
    throw new IllegalArgumentException(e);
StringgetString(ByteBuffer buffer)
get String 
Charset charset = null;
CharsetDecoder decoder = null;
CharBuffer charBuffer = null;
try {
    charset = Charset.forName("UTF-8");
    decoder = charset.newDecoder();
    charBuffer = decoder.decode(buffer.asReadOnlyBuffer());
    return charBuffer.toString();
...
StringgetString(ByteBuffer buffer)
get String 
StringBuilder sb = new StringBuilder(buffer.limit());
while (buffer.remaining() > 0) {
    char c = (char) buffer.get();
    if (c == 0)
        break;
    sb.append(c);
return sb.toString();
...
StringgetString(ByteBuffer buffer, int length)
get String 
StringBuilder builder = new StringBuilder();
for (int i = 0; i < length; i++) {
    builder.append((char) buffer.get());
return builder.toString();
StringgetString(ByteBuffer buffer, int offset, int length, String encoding)
Create String offset from position by offset upto length using encoding, and position of buffer is moved to after position + offset + length 
byte[] b = new byte[length];
buffer.position(buffer.position() + offset);
buffer.get(b);
try {
    return new String(b, 0, length, encoding);
} catch (UnsupportedEncodingException uee) {
    throw new RuntimeException(uee);
StringgetString(ByteBuffer buffer, int size)
get String 
byte[] result = new byte[size];
buffer.get(result);
return new String(result, CHARSET);
StringgetString(ByteBuffer buffer, int size)
get String 
assert (0 < size);
assert (buffer.capacity() - buffer.position() >= size);
ByteBuffer buf = ByteBuffer.allocate(size);
buffer.get(buf.array(), 0, size);
try {
    return Charset.defaultCharset().newDecoder().decode(buf).toString().trim();
} catch (Exception e) {
    e.printStackTrace();
...
StringgetString(ByteBuffer buffer, String charFormat)
get String 
String result;
int length;
if (charFormat == "UTF-16LE") {
    length = buffer.order(ByteOrder.LITTLE_ENDIAN).getInt();
} else {
    length = buffer.order(ByteOrder.LITTLE_ENDIAN).getShort();
int bufferPosition = buffer.position();
...
StringgetString(ByteBuffer byteBuffer, int size)
get String 
byte[] bytes = new byte[size];
byteBuffer.get(bytes);
return new String(bytes, Charset.defaultCharset());
