Detailed Description

template<typename T>
class gis::Unary_functor< T >

The base class of all functors that take one geometry argument.

Subclasses of this functor base class will implement operator() and call apply() to do type combination dispatching. The actual body of the functor is in the eval() member function, which must be implemented for each different parameter type combination.

The functor may throw exceptions.

Template Parameters
TThe return type of the functor.
