Detailed Description

Apply a one-input func to the field: call operator()(const Vec& input) of the func, with the input vector set to the single value resulting from the conversion of the SDB field to a Real. The vector output by the func is kept completely in the output; in other words, fieldWidth() is equal to the size of the vector returned by the func.

Member Function Documentation

void PLearn::SDBVMFieldFunc1::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. Implements PLearn::SDBVMField. Definition at line 404 of file SDBVMat.cc. References func_, PLearn::SDBVMSource::getValue(), and PLearn::Vec.

int PLearn::SDBVMFieldFunc1::fieldWidth (   )  const [virtual]

Width that the field occupies in the VMat. Implements PLearn::SDBVMField. Definition at line 413 of file SDBVMat.cc. References func_.
