Method Detail

readUnsignedLTF8

public static long readUnsignedLTF8(java.io.InputStream inputStream)

Reads an unsigned long value from the input stream. The sign bit should be interpreted just as other bits in the value.

Parameters:

inputStream - input stream to be read from

Returns:

value encoded in the stream as LTF8

writeUnsignedLTF8

public static int writeUnsignedLTF8(long value,
                                    java.io.OutputStream outputStream)

Writes an unsigned long value to the output stream. The sign bit is interpreted just as other bits in the value.

Parameters:

value - the value to be written

outputStream - the output stream to write to

Returns:

the number of bits written
