void PLearn::SourceVMatrix::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::VMatrix.

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

This does the actual building. Reimplemented from PLearn::VMatrix. Reimplemented in PLearn::BootstrapVMatrix, PLearn::CenteredVMatrix, PLearn::CumVMatrix, PLearn::FilteredVMatrix, PLearn::GetInputVMatrix, PLearn::KNNVMatrix, PLearn::LocalNeighborsDifferencesVMatrix, PLearn::MovingAverageVMatrix, PLearn::PrecomputedVMatrix, PLearn::ProcessingVMatrix, PLearn::RemoveDuplicateVMatrix, PLearn::RowsSubVMatrix, PLearn::SelectColumnsVMatrix, PLearn::SelectRowsVMatrix, PLearn::SortRowsVMatrix, PLearn::SubInputVMatrix, PLearn::TransposeVMatrix, and PLearn::UpsideDownVMatrix.

void PLearn::SourceVMatrix::declareOptions (  OptionList &  ol  )  [static, protected]

Declares this class' options. Reimplemented from PLearn::VMatrix. Reimplemented in PLearn::BootstrapVMatrix, PLearn::CenteredVMatrix, PLearn::CumVMatrix, PLearn::FilteredVMatrix, PLearn::GetInputVMatrix, PLearn::KNNVMatrix, PLearn::LocalNeighborsDifferencesVMatrix, PLearn::MovingAverageVMatrix, PLearn::PrecomputedVMatrix, PLearn::ProcessingVMatrix, PLearn::RemoveDuplicateVMatrix, PLearn::RowsSubVMatrix, PLearn::SelectColumnsVMatrix, PLearn::SelectRowsVMatrix, PLearn::SortRowsVMatrix, PLearn::SubInputVMatrix, PLearn::TransposeVMatrix, and PLearn::UpsideDownVMatrix.

void PLearn::SourceVMatrix::getNewRow (  int  i, const Vec &  v )  const [protected, virtual]

Must be implemented in subclasses: default version returns an error. Implements PLearn::RowBufferedVMatrix. Reimplemented in PLearn::CenteredVMatrix, PLearn::CumVMatrix, PLearn::FilteredVMatrix, PLearn::KNNVMatrix, PLearn::LocalNeighborsDifferencesVMatrix, PLearn::PrecomputedVMatrix, PLearn::ProcessingVMatrix, PLearn::SelectColumnsVMatrix, PLearn::SelectRowsVMatrix, PLearn::SubInputVMatrix, and PLearn::TransposeVMatrix.

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

Transforms a shallow copy into a deep copy. Reimplemented from PLearn::RowBufferedVMatrix. Reimplemented in PLearn::CenteredVMatrix, PLearn::CumVMatrix, PLearn::FilteredVMatrix, PLearn::GetInputVMatrix, PLearn::KNNVMatrix, PLearn::LocalNeighborsDifferencesVMatrix, PLearn::MovingAverageVMatrix, PLearn::PrecomputedVMatrix, PLearn::ProcessingVMatrix, PLearn::RemoveDuplicateVMatrix, PLearn::RowsSubVMatrix, PLearn::SelectColumnsVMatrix, PLearn::SelectRowsVMatrix, PLearn::SortRowsVMatrix, PLearn::SubInputVMatrix, PLearn::TransposeVMatrix, and PLearn::UpsideDownVMatrix. Definition at line 169 of file SourceVMatrix.cc. References PLearn::deepCopyField(), source, and sourcerow.

PLearn::SourceVMatrix::PLEARN_DECLARE_OBJECT (  SourceVMatrix   )

Declares name and deepCopy methods.

void PLearn::SourceVMatrix::setMetaDataDir (  const string &  the_metadatadir  )  [virtual]

Also sets the source's meta-data dir if it's not already set. If there are fields that have no corresponding .smap .notes or .binning info files but the source has those files for a field with the same name, then those of the source will be set also for this vmatrix. Reimplemented from PLearn::VMatrix. Reimplemented in PLearn::FilteredVMatrix, PLearn::PrecomputedVMatrix, and PLearn::ProcessingVMatrix. Definition at line 65 of file SourceVMatrix.cc. References PLearn::file_exists(), PLearn::VMatrix::hasFieldInfos(), slash, and source.

void PLearn::SourceVMatrix::setMetaInfoFromSource (   )  [protected]

Sets all meta info (length_, width_, inputsize_, targetsize_, weightsize_, fieldnames, ...) that is not already set, by copying it from the source's Modification time is also set to the latest of the current mtime of this vmat and of the mtime of the source. This method is mostly to simplify writing subclass' build_ method, which may call it after first setting the fields that it doesn't want copied from the source.
