void PLearn::VMatLanguage::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 84 of file VMatLanguage.cc.
References build_().

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

This method should be redefined in subclasses and do the actual building of the object according to previously set option fields. Constructors can just set option fields, and then call build_. This method is NOT virtual, and will typically be called only from three places: a constructor, the public virtual build() method, and possibly the public virtual read method (which calls its parent's read). build_() can assume that it's parent's build_ has already been called.

void PLearn::VMatLanguage::build_opcodes_map ( ) [static, private]

void PLearn::VMatLanguage::compileStream ( istream & in,

vector< string > & fieldnames

)

takes a string, filename, or istream and generate the bytecode from it On exit, fieldnames will contain fieldnames of the resulting matrix The source vmat must be set before compiling a VPL program.

void PLearn::VMatLanguage::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); }
