Detailed Description
The Read By Group Type Response is sent in reply to a received Read By Group Type Request and contains the handles and values of the attributes that have been read.
The response is a list of group range-value pair where:
- group range: The range of the group found where begin is the grouping attribute handle and end is the handle of the end of the group.
- value: The value of the grouping attribute.
This class has to be subclassed by an implementation specific class defining the member function size and the subscript operator.
- Note:
- The value responded can be trucated if it doesn't fit in the response, in that case a Read Blob Request could be used to read the remaining octets.
