void PLearn::JoinVMatrix::addStatField (  const string &  statis, const string &  namefrom, const string &  nameto )

Definition at line 93 of file JoinVMatrix.cc. References fld, PLERROR, slave, and PLearn::VMatrix::width(). Referenced by PLearn::VVMatrix::processJoinSection().

void PLearn::JoinVMatrix::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 55 of file JoinVMatrix.cc. References build_(). Referenced by JoinVMatrix().

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

This does the actual building. Reimplemented from PLearn::VMatrix. Definition at line 62 of file JoinVMatrix.cc. References PLearn::VMat::fieldName(), PLearn::VMat::length(), master, master_idx, mp, PLERROR, PLearn::TVec< T >::resize(), PLearn::TVec< int >::size(), slave, slave_idx, temp, tempkey, PLearn::VMat::width(), and PLearn::VMatrix::width(). Referenced by build().

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

redefine this in subclasses: call declareOption(...) for each option, and then call inherited::declareOptions(options) ( see the declareOption function further down) ex: static void declareOptions(OptionList& ol) { declareOption(ol, "inputsize", &MyObject::inputsize_, OptionBase::buildoption, "the size of the input\n it must be provided"); declareOption(ol, "weights", &MyObject::weights, OptionBase::learntoption, "the learnt model weights"); inherited::declareOptions(ol); } Reimplemented from PLearn::VMatrix. Definition at line 84 of file JoinVMatrix.cc. References PLearn::declareOption(), and PLearn::OptionList.

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

This is the only method requiring implementation in subclasses. Implements PLearn::RowBufferedVMatrix. Definition at line 126 of file JoinVMatrix.cc. References count, fld, PLearn::is_missing(), master, master_idx, PLearn::max(), PLearn::min(), mp, PLERROR, PLearn::TVec< int >::size(), slave, PLearn::sqrt(), PLearn::TVec< T >::subVec(), PLearn::sum(), PLearn::sumsquare(), temp, tempkey, val, PLearn::VMatrix::width(), and PLearn::VMat::width().

const map< real, string > & PLearn::JoinVMatrix::getRealToStringMapping (  int  col  )  const [virtual]

returns the value->string mapping for field 'fld' Reimplemented from PLearn::VMatrix. Definition at line 232 of file JoinVMatrix.cc. References master, slave, and PLearn::VMat::width().

string PLearn::JoinVMatrix::getString (  int  row, int  col )  const [virtual]

returns element as a string, even if value doesn't map to a string, in which case tostring(value) is returned Reimplemented from PLearn::VMatrix. Definition at line 241 of file JoinVMatrix.cc. References master, slave, and PLearn::VMat::width().

const map< string, real > & PLearn::JoinVMatrix::getStringToRealMapping (  int  col  )  const [virtual]

returns the string->value mapping for field 'fld' Reimplemented from PLearn::VMatrix. Definition at line 223 of file JoinVMatrix.cc. References master, slave, and PLearn::VMat::width().

real PLearn::JoinVMatrix::getStringVal (  int  col, const string &  str )  const [virtual]

returns value associated with a string (or MISSING_VALUE if there's no association for this string) Reimplemented from PLearn::VMatrix. Definition at line 215 of file JoinVMatrix.cc. References master, slave, and PLearn::VMat::width().

string PLearn::JoinVMatrix::getValString (  int  col, real  val )  const [virtual]

returns the string associated with value val for field# col. Or returns "" if no string is associated. Reimplemented from PLearn::VMatrix. Definition at line 207 of file JoinVMatrix.cc. References master, slave, val, and PLearn::VMat::width().
