Member Function Documentation

void PLearn::AsciiVMatrix::appendRow (  Vec  v  )  [virtual]

Append a row at the end of the file. Reimplemented from PLearn::VMatrix. Definition at line 263 of file AsciiVMatrix.cc. References PLearn::endl(), file, PLearn::VMatrix::length(), PLearn::TVec< T >::length(), length_max, PLERROR, pos_rows, readwritemode, rewrite_length, vmatlength_pos, and PLearn::VMatrix::width().

void PLearn::AsciiVMatrix::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. Definition at line 107 of file AsciiVMatrix.cc. References build_(). Referenced by AsciiVMatrix().

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

This does the actual building. Reimplemented from PLearn::VMatrix. Definition at line 113 of file AsciiVMatrix.cc. References PLearn::countNonBlankLinesOfFile(), file, filename, PLearn::getNextNonBlankLine(), PLearn::isfile(), length_max, PLearn::log(), newfile, PLERROR, PLWARNING, pos_rows, PLearn::pow(), PLearn::removeblanks(), PLearn::removenewline(), rewrite_length, PLearn::split(), PLearn::toint(), vmatlength_pos, and PLearn::ws(). Referenced by build().

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

Declares this class' options. Reimplemented from PLearn::VMatrix. Definition at line 299 of file AsciiVMatrix.cc. References PLearn::declareOption(), and PLearn::OptionList.

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

This is the only method requiring implementation. Implements PLearn::RowBufferedVMatrix. Definition at line 249 of file AsciiVMatrix.cc. References file, PLearn::TVec< T >::length(), PLearn::VMatrix::length(), PLERROR, pos_rows, PLearn::Vec, and PLearn::VMatrix::width().

PLearn::AsciiVMatrix::PLEARN_DECLARE_OBJECT (  AsciiVMatrix   )

Declares name and deepCopy methods.

void PLearn::AsciiVMatrix::put (  int  i, int  j, real  value )  [virtual]

These methods send an error message since, by choice, we accept only to append row at the end of the file. Reimplemented from PLearn::VMatrix. Definition at line 292 of file AsciiVMatrix.cc. References PLERROR.

void PLearn::AsciiVMatrix::putRow (  int  i, Vec  v )  [virtual]

Reimplemented from PLearn::VMatrix. Definition at line 296 of file AsciiVMatrix.cc. References PLERROR.

void PLearn::AsciiVMatrix::putSubRow (  int  i, int  j, Vec  v )  [virtual]

It is suggested that this method be implemented in subclasses of writable matrices to speed up accesses (default version repeatedly calls put(i,j,value) which may have a significant overhead) Reimplemented from PLearn::VMatrix. Definition at line 294 of file AsciiVMatrix.cc. References PLERROR.
