#7 IEvaluator problems

[Jan Strube]

Using the IEvaluator with a function on a column fails.
example:
File "/nfs/slac/g/lcd/mc/prj/sw/extern/python2.4/lib/python2.4/site-packages/paida/paida_core/ITuple.py", line 282, in project
histogramFill(evaluatDoubleX())
File "/nfs/slac/g/lcd/mc/prj/sw/extern/python2.4/lib/python2.4/site-packages/paida/paida_core/IEvaluator.py", line 26, in evaluateDouble
return float(eval(self._code, self._globals, {'_row': self._tupleRows[self._tupleObject._rowIndex]}))
File "IEvaluator.py", line 0, in ?
NameError: name 'sqrt' is not defined

In this case I tried to make a new column from existing columns using sqrt.
This is possible in JAIDA and JAS, and it should be possible by just importing everything from math into IEvaluator.
Cheers,
Jan

I've fixed and checked new IEvaluator.py file into CVS.
Thanks, Jan!
