Member Function Documentation

void PLearn::SortRowsVMatrix::build (   )  [virtual]

Should call simply inherited::build(), then this class's build_(). This method should be callable again at later times, after modifying some option fields to change the "architecture" of the object. Reimplemented from PLearn::SelectRowsVMatrix. Definition at line 82 of file SortRowsVMatrix.cc. References build_().

void PLearn::SortRowsVMatrix::build_ (   )  [private]

This does the actual building. Reimplemented from PLearn::SelectRowsVMatrix. Definition at line 91 of file SortRowsVMatrix.cc. References increasing_order, PLearn::TVec< int >::isNotEmpty(), PLearn::VMat::length(), PLearn::TVec< int >::length(), PLERROR, sort_columns, and PLearn::sortRows(). Referenced by build().

void PLearn::SortRowsVMatrix::declareOptions (  OptionList &  ol  )  [static]

Declares this class' options. Reimplemented from PLearn::SelectRowsVMatrix. Definition at line 62 of file SortRowsVMatrix.cc. References PLearn::declareOption(), and PLearn::OptionList.

void PLearn::SortRowsVMatrix::makeDeepCopyFromShallowCopy (  map< const void *, void * > &  copies  )  [virtual]

Transforms a shallow copy into a deep copy. Reimplemented from PLearn::SelectRowsVMatrix. Definition at line 73 of file SortRowsVMatrix.cc. References PLearn::deepCopyField(), and sort_columns.

PLearn::SortRowsVMatrix::PLEARN_DECLARE_OBJECT (  SortRowsVMatrix   )

void PLearn::SortRowsVMatrix::sortRows (  VMat &  m, TVec< int > &  indices, TVec< int > &  sort_columns, int  istart, int  iend, int  colstart, bool  increasing_order )  [static, private]

This function returns in indices the sorting of the rows of a VMat m, according to the columns specified by sort_columns[colstart, ...], where m is viewed as ordered by the indices given at calling time. Only the samples between istart and iend are considered. Definition at line 114 of file SortRowsVMatrix.cc. References PLearn::TVec< T >::size(), PLearn::sortRows(), and val.
