Method

voidtoArray(IntBuffer src, int[] dst, int offset)
to Array 
src.position(0);
src.get(dst, offset, dst.length - offset);
byte[]toArray(long length)
to Array 
long value = length;
byte[] b = new byte[8];
for (int i = 7; i >= 0 && value > 0; i--) {
    b[i] = (byte) (value & 0xFF);
    value >>= 8;
return b;
byte[]toASCII(String str)
to ASCII 
try {
    return str.getBytes("US-ASCII");
} catch (UnsupportedEncodingException e) {
    throw new RuntimeException(e);
ByteBuffertoAsciiBytes(String s)
to Ascii Bytes 
return put(ByteBuffer.allocate(s.length()), s);
StringtoASCIIString(URI u)
Returns the content of this URI as a US-ASCII string. 
String s = defineString(u);
return encode(s);
AttributeValuetoAttributeValue(Object value)
Copied from DynamoDB Document SDK InternalUtils.java Converts a simple value into the low-level representation. 
AttributeValue result = new AttributeValue();
if (value == null) {
    return result.withNULL(Boolean.TRUE);
} else if (value instanceof Boolean) {
    return result.withBOOL((Boolean) value);
} else if (value instanceof String) {
    return result.withS((String) value);
} else if (value instanceof BigDecimal || value instanceof Number) {
