Constructor & Destructor Documentation

PLearn::SDBVMFieldDateDiff::SDBVMFieldDateDiff (  SDBVMSource  source1, SDBVMSource  source2, char  the_unit = 'D', FieldValue  date1_threshold = FieldValue(), FieldValue  date2_threshold = FieldValue() )  [inline]

unit can be 'D' for days, 'M' for months or 'Y' for years (result is always an integer number of days, months, or years) This will compute difference between dates in source1 and source2 The sources must both be dates. Optionally, two thresholds can be specified, such that if a date is below or equal to its respective threshold, then the date is considered MISSING_VALUE. This is useful to filter out some obvious outliers. (TO BE IMPLEMENTED: or one can be a date and the other an integer numerical type; in this latter case, the integer is understood as beeing expressed in the given unit...) Definition at line 577 of file SDBVMat.h. References MISSING_VALUE.

PLearn::SDBVMFieldDateDiff::SDBVMFieldDateDiff (  SDBVMSource  source1, PDate  the_refdate, char  the_unit = 'D' )  [inline]

This will compute difference between date in source1 and a fixed refdate. Definition at line 586 of file SDBVMat.h. References MISSING_VALUE.

void PLearn::SDBVMFieldDateDiff::convertField (  const SDBWithStats &  sdb, const Row &  row, const Vec &  output )  const [virtual]

Given a database row, convert the appropriate parts to a (preallocated) output vector of the correct width (given by fieldWidth). Replace MISSING_VALUEs by missing_values_mapping.

int PLearn::SDBVMFieldDateDiff::fieldWidth (   )  const [virtual]

Width that the field occupies in the VMat. Implements PLearn::SDBVMField. Definition at line 580 of file SDBVMat.cc.
