Interface FunctorFactory

All Known Implementing Classes:

StdFunctorFactory

public interface FunctorFactory

when expressions are being parsed, the parser makes callbacks to implementation of this interface to create the necessary functors. This provides a level of flexability if it's necessary to override the behavior of one or several functors.

This may be useful to allow a new data type to be operated on.
