void PLearn::UnaryHardSlopeVariable::build | ( | ) | [virtual] |
Post-constructor.
The normal implementation 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.

void PLearn::UnaryHardSlopeVariable::build_ | ( | ) | [protected] |
Object-specific post-constructor.
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 its parent's build_()
has already been called.

void PLearn::UnaryHardSlopeVariable::declareOptions | ( | OptionList & | ol | ) | [static] |
Declare options (data fields) for the class.
Redefine this in subclasses: call declareOption
(...) for each option, and then call inherited::declareOptions(options)
. Please call the inherited
method AT THE END to get the options listed in a consistent order (from most recently defined to least recently defined).

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.
