If you remove the virtual keyword then the function doesn't get put into the virtual function table. Therefore, I believe any calls to the function are bound to the function within the type's class. Since yahoo is using base, all calls it makes inside that class are bound to base's function. However, virtual functions are always bound to the vtable (unless you explicitly override it).

transferfunct
TransferFunct(3U) InterViews Reference Manual TransferFunct(3U)
NAME
TransferFunct - transfer function base class
SYNOPSIS
#include <Unidraw/transfn.h>
DESCRIPTION
A transfer function defines relationships between state variables. A component uses a transfer function to enforce dependencies between
its state variables during dataflow. State variables whose values change as a result of data flowing into the component can thus affect the
component's dependent state variables as defined by its transfer function. A transfer function can define dependencies between any number
of state variables, but a component can define only one transfer function.
PUBLIC OPERATIONS
virtual void Evaluate(Path* = nil)
Enforce the transfer function's dependencies between its state variables, optionally depending on the information in a path. This
operation does nothing by default.
virtual TransferFunct* Copy()
Return a copy of the transfer function. Subclasses redefine this operation to return an instance of their type.
virtual void Read(istream&)
virtual void Write(ostream&)
Read and write the transfer function's contents to a stream to support catalog operations. Read and write typically call first the
corresponding operations defined by their parent class, and then they read or write their class-specific state.
virtual ClassId GetClassId()
virtual boolean IsA(ClassId)
GetClassId returns the unique class identifier for the TransferFunct subclass, while IsA returns whether the instance is of a class
or subclass corresponding to the given identifier. IsA typically checks the given identifier against the instance's own (as defined
by its GetClassId operation) and, failing that, calls its parent classes' IsA operation. All subclasses must redefine GetClassId
and IsA to ensure that their identifiers are unique and that instances are written and read properly.
PROTECTED OPERATIONS
TransferFunct()
The constructor is protected to prevent instantiation.
virtual Connector* GetBinding(StateVar*)
Return the connector to which a state variable is bound.
