Description copied from interface: IByteArrayDecoder

Decode a byte array.

Specified by:

getDecoded in interface IByteArrayDecoder

Parameters:

aEncodedBuffer - The byte array to be decoded. May be null.

nOfs - Offset into the byte array to start from.

nLen - Number of bytes starting from offset to consider.

Returns:

The decoded byte array or null if the parameter was null.
