Description

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

Method

StringtoString(ByteBuffer bytes)
Extract the byte[] within the given ByteBuffer and decode into a String using UTF-8. 
return toString(copyBytes(bytes));
StringtoString(ByteBuffer sequence)
Convert a byte buffer to a string in platform default encoding. 
return new String(sequence.array(), sequence.position(), sequence.remaining());
StringtoString(ByteBuffer value, String charsetName)
convert a ByteBuffer to a String ByteBuffer is reset to its original state. 
String result = null;
try {
    result = new String(toBytes(value), charsetName);
} catch (Exception e) {
return result;
StringtoString(final ByteBuffer buffer)
Returns the buffer as a string while preserving the buffer position and limit. 
final int position = buffer.position();
final int limit = buffer.limit();
final byte[] data = new byte[buffer.remaining()];
buffer.get(data);
final String dataString = new String(data);
buffer.position(position);
buffer.limit(limit);
return dataString;
...
StringtoString(final ByteBuffer buffer)
Convert ByteBuffer to string, assuming UTF-8 encoding in the buffer. 
byte[] array = new byte[buffer.remaining()];
buffer.get(array);
return new String(array, Charset.forName("UTF-8"));
StringtoString(final ByteBuffer buffer)
Converts a byte buffer into a string in the UTF-8 character set. 
return toCharBuffer(buffer).toString();
StringtoStringBinary(ByteBuffer buf)
Converts the given byte buffer, from its array offset to its limit, to a string. 
if (buf == null)
    return "null";
return toStringBinary(buf.array(), buf.arrayOffset(), buf.limit());
StringtoStringBinary(ByteBuffer buf)
Converts the given byte buffer, from its array offset to its limit, to a string. 
if (buf == null)
    return "null";
return toStringBinary(buf.array(), buf.arrayOffset(), buf.limit());
voidtoText(ByteBuffer data, StringBuilder result, int cnt)
Gets last cnt read bytes from the data buffer and puts into result buffer in special format:
  • if byte represents char from partition 0x1F to 0x80 (which are normal ascii chars) then it's put into buffer as it is
  • otherwise dot is put into buffer
int charPos = data.position() - cnt;
for (int a = 0; a < cnt; a++) {
    int c = data.get(charPos++);
    if (c > 0x1f && c < 0x80)
        result.append((char) c);
    else
        result.append('.');
StringtoTextAll(ByteBuffer bytes)
Convert whole byte buffer to UTF-8 String. 
return new String(bytes.array(), UTF8);
