Detailed Description
Response to a Read By Type request.
It contains a list of handle-value pairs where:
- handle is the handle of the attribute matching the rype requested.
- value is the value of the attribute found. If the value is longer than (mtu - 4) then it can be truncated and read blob request should be used to read the remaining octet of the attribute.
This class has to be subclassed by an implementation specific class defining the member function size and the subscript operator.
