Specified by:

expectedObjectWidth in interface ObjectDecoder<STRING_LIKE_TYPE extends CharSequence>

Returns:

VARIABLE_WIDTH_SENTINEL if the codec must encode and decode variable width columns, otherwise the fixed size of byte array that must be decoded and encoded.

Decode an object from an array of bytes.

Specified by:

decode in interface ObjectDecoder<STRING_LIKE_TYPE extends CharSequence>

Parameters:

data - The input byte array containing bytes to decode

offset - The offset into the byte array to start decoding from

length - The length of the byte array to decode from, starting at the offset

Returns:
