Member Function Documentation

void PLearn::SequentialSplitter::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::Object.
Definition at line 74 of file SequentialSplitter.cc.
References build_().

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

This does the actual building.

Reimplemented from PLearn::Object.
Definition at line 69 of file SequentialSplitter.cc.
Referenced by build().

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

Declares this class' options.

Reimplemented from PLearn::Object.
Definition at line 55 of file SequentialSplitter.cc.
References PLearn::declareOption(), and PLearn::OptionList.

TVec< VMat > PLearn::SequentialSplitter::getSplit ( int i = 0 ) [virtual]

Returns split number i.

Implements PLearn::Splitter.

int PLearn::SequentialSplitter::nSetsPerSplit ( ) const [virtual]

Returns the number of sets per split.
