Inheritance diagram for PLearn::EqualConstantVariable:
Public Member Functions | |
EqualConstantVariable () | |
Default constructor for persistence. | |
EqualConstantVariable (Variable *input1, real input2) | |
PLEARN_DECLARE_OBJECT (EqualConstantVariable) | |
virtual string | info () const |
returns a bit more informative string about object (default returns classname()) | |
virtual void | recomputeSize (int &l, int &w) const |
Recomputes the length l and width w that this variable should have, according to its parent variables. | |

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::UnaryVariable.

Recomputes the length l and width w that this variable should have, according to its parent variables. This is used for ex. by sizeprop() The default version stupidly returns the current dimensions, so make sure to overload it in subclasses if this is not appropriate.
