BinaryFieldInterpreter
Decodes only one data of type T from the given bytes array.
WARNING: bytes
is supposed to contain enough bytes (>= BinaryFieldInterpreter.NB_BYTES
) from the given offset.

BinaryFieldInterpreter
Gets the precise array type.
Generally: T[].class
, where T must be a concrete class.
