[tracecompass-dev] Questions about trace filters and timestamps

["David Wootton" <dwootton@xxxxxxxxxx>]

I constructed a filter for the timestamp column of my trace, where the set of trace aspects includes the Timestamp aspect from the TmfBaseAspects class.

If I construct a filter using the EQUALS operator, it acts as it there is a strict string comparison, including any trailing spaces in the value specified in the field, and will match the single row in the trace with the timestamp as long as there are no trailing spaces in the value in the filter.

If I construct a filter using the COMPARE operator for the timestamp column that only seems to work correctly when I define the data type as alpha. If I use the timestamp type, it seems like all rows pass the filter.

Is the intent for the Timestamp aspect to be treated as a String? How would the timestamp type be used?
