Description

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

Method

StringtoString(Reader reader)
to String 
StringWriter sw = new StringWriter();
copyStream(reader instanceof BufferedReader ? (BufferedReader) reader : new BufferedReader(reader),
        new BufferedWriter(sw));
return sw.toString();
StringtoText(@Nonnull byte[] bytes)
to Text 
StringBuilder buf = new StringBuilder();
for (byte b : bytes) {
    if (Character.isValidCodePoint(b))
        buf.append((char) b);
    else
        buf.append("\\x").append(UnsignedBytes.toString(b, 16));
return buf.toString();
...
byte[]toThriftBinary(UUID uuid)
to Thrift Binary 
ByteBuffer bb = ByteBuffer.wrap(new byte[UUID_BYTES]);
bb.putLong(uuid.getMostSignificantBits());
bb.putLong(uuid.getLeastSignificantBits());
return bb.array();
URItoURI(String value)
Convert a string to java.net.URI If part name is not a valid URI, it is resolved as follows:

1. 

if (value.indexOf("\\") != -1) {
    value = value.replace('\\', '/');
int fragmentIdx = value.indexOf('#');
if (fragmentIdx != -1) {
    String path = value.substring(0, fragmentIdx);
    String fragment = value.substring(fragmentIdx + 1);
    value = path + "#" + encode(fragment);
...
StringtoUTF(byte[] bytes)
Converts a byte array into an UTF String. 
int codePoint = ByteBuffer.wrap(bytes).getInt();
if (codePoint < 0 || codePoint > 0X10FFFF)
    throw new IllegalArgumentException("RangeError: pack(U): value out of range");
return String.valueOf((char) codePoint);
byte[]toUTF8(String str)
In all src and test code, the String(byte[], ...) constructor and String.getBytes method must always be passed a Charset, to avoid portability issues. 
try {
    return str.getBytes("UTF-8");
} catch (UnsupportedEncodingException e) {
    throw new RuntimeException(e);
UUIDtoUuid(byte[] bytes)
to Uuid 
ByteBuffer bb = ByteBuffer.wrap(bytes);
long hi = bb.getLong();
long lo = bb.getLong();
return new UUID(hi, lo);
java.util.UUIDtoUUID(byte[] uuid)
Returns an instance of uuid. 
return uuid(uuid, 0);
byte[]toUUIDBinary(UUID uuid)
to UUID Binary 
ByteBuffer bb = ByteBuffer.allocate(16);
bb.putLong(uuid.getMostSignificantBits()).putLong(uuid.getLeastSignificantBits());
return bb.array();
