Description

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

Method

StringreadUTF(ByteBuffer bb)
Reads from the bytebuffer bb a representation of a Unicode character string encoded in modified UTF-8 format; this string of characters is then returned as a String. 
int utflen = readUnsignedShort(bb);
byte[] bytearr = new byte[utflen];
char[] chararr = new char[utflen];
int c, char2, char3;
int count = 0;
int chararr_count = 0;
bb.get(bytearr);
while (count < utflen) {
...
StringreadUTF8(ByteBuffer buf)
read UTF 
short len = buf.getShort();
byte[] str = new byte[len];
buf.get(str);
String res = null;
try {
    res = new String(str, "UTF-8");
} catch (UnsupportedEncodingException ex) {
    res = "";
...
StringreadUTFString(MappedByteBuffer mmap)
read UTF String 
byte[] encodedString = new byte[mmap.getShort()];
mmap.get(encodedString);
return new String(encodedString, Charset.forName("UTF-8"));
CharBuffertoUtf8CharBuffer(ByteBuffer buffer)
Converts the input ByteBuffer in an UTF-8 CharBuffer . 
return UTF_8.decode(buffer);
StringtoUtf8String(ByteBuffer buffer)
to Utf String 
if (!buffer.hasRemaining()) {
    return EMPTY;
if (buffer.hasArray()) {
    return new String(buffer.array(), buffer.arrayOffset() + buffer.position(), buffer.remaining(),
            StandardCharsets.UTF_8);
} else {
    byte[] content = new byte[buffer.remaining()];
...
StringtoUTF8String(ByteBuffer buffer)
Convert the buffer to an UTF-8 String 
return toString(buffer, StandardCharsets.UTF_8);
StringtoUtf8String(ByteBuffer byteBuffer)
to Utf String 
byte[] bytes = new byte[byteBuffer.remaining()];
byteBuffer.get(bytes);
return new String(bytes, UTF_8);
