Method Details

expectedObjectWidth

public final int expectedObjectWidth()

Description copied from interface: ObjectDecoder

What width byte array does this ObjectCodec expect to encode and decode?

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

 int offset,
 int length)

Description copied from interface: ObjectDecoder

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 number of bytes to decode, starting at the offset

Returns:

The output object, possibly null
