bool Merge(uint64_t start, uint64_t end)

Merge the span defined by start and end into the map.

This operation compares the candidate span, defined by "start" and "end", with all spans that exist in the map prior to this call. If the candidate is completely "covered" by all existing spans (that is, it adds nothing new to the aggregate data), then it is "rejected" and the operation returns "false". Otherwise, the collection of spans is modified to accommodate the candidate's contribution and the operation returns "true".

Note

In all existing and candidate spans, "start" must be less than or equal to "end".

Parameters

start -- Start of the candidate span
end -- End of the candidate span

Returns

True if the operation resulted in modification of existing spans; false otherwise
