[Nick Draper]

Rob Dalgleish needs to access period specific log values in python

Add a test to LogFilterTest Refs #5203

Needs debugging by Wendou for it to be turned on.

To test:

from mantid.kernel import LogFilter
from mantid.simpleapi import Load

testWS = Load(Filename="CSP78173.raw", OutputWorkspace='testWS')
print testWS
ws = testWS[6] #period 7
print ws
run_info = ws.getRun()
height_log = run_info.getLogData("height")
period_log = run_info.getLogData("period 7")

print 'N log values %d' % height_log.size()
filter = LogFilter(height_log)
filter.addFilter(period_log)        
filteredLog = filter.data()
print 'N log values after filter %d' % filteredLog.size()

I've made an error here. I assumed the value method on timeseries property would only give back the filtered data but it doesn't, you need the nthValue, nthTime, nthInterval methods to access the filtered data and I haven't exposed them.

Basically the filtering is useless without them. On the bright side the are trivial to expose

Exports filtered data methods to python. Refs #5203

Without these you cannot access filtered data at all.

Tested by running the script.
