Detailed Description

A functor class wrapping a pickled python lambda string.

The lambda type is assumed to be either: S -> T or or List -> T. where all types should be compatible with flexible_type.

Note

: currently only support basic flexible_types: flex_string, flex_int, flex_float

All public member functions including the constructors are guarded by the global mutex, preventing simultanious access to the python's GIL.

Internally, the class stores a a python lambda object which is created from the pickled lambda string upon construction. The lambda object is equivalent to a python lambda object (with proper reference counting), and therefore, the class is copiable.
