Method

char[]getChars(ByteBuffer buf, int off, int count)
Returns a character array from the buffer. 
char[] chars = new char[count];
buf.position(off);
for (int ii = 0; ii < count; ii++)
    chars[ii] = buf.getChar();
return chars;
chargetCPCharacter(ByteBuffer buffer)
get CP Character 
int read = buffer.get() & 0xff;
if (read == 0) {
    throw new IllegalArgumentException(
            "Non cp1252 character 0x" + Integer.toString(read, 16) + " provided");
if (read >= 128 && read < 160) {
    char cpChar = CHARACTERS[read - 128];
    if (cpChar == '\0') {
...
intgetCrcChecksum(ByteBuffer buffer)
Calculates the CRC32 checksum of the specified buffer. 
Checksum crc = new CRC32();
