                                 FValueAnnotator

See if the string value (svalue) of the annotation can be parsed as a float value. If so, fill in the fvalue (float value) column.

Instance Methods

allColumns(self)
Return an ordered sequence of all the column names that this multiple annotator can generate values for.

allValues(self, input)
Assume input to be a tab-delimited string with values corresponding to the columns of the annotation table, in the following order (s2c_id, name, svalue, fvalue):

Inherited from BaseAnnotator.SingleAnnotator: __call__, __init__, columnName

Inherited from BaseAnnotator.BaseAnnotator: annotateDict, iteritems, iterkeys, itervalues, keys, specifyColumns, values

Method Details

[hide private]

allColumns(self)

Return an ordered sequence of all the column names that this multiple annotator can generate values for.

To facilitate ease of filtering with case-insensitivity, all of the values returned by this method should be lowercase.

Overrides: BaseAnnotator.BaseAnnotator.allColumns: (inherited documentation)

allValues(self, input)

Assume input to be a tab-delimited string with values corresponding to the columns of the annotation table, in the following order (s2c_id, name, svalue, fvalue):

>>> annotator = FValueAnnotator();
>>> input = "1 TestStr TestVal None";
>>> print annotator(input);
None
>>> input = "2 TestInt 0 None";
>>> print "%.1f" % annotator(input);
0.0
>>> input = "3 TestFloat 43.21 None";
>>> print "%.1f" % annotator(input);
43.2
