Detailed Description

template<class T>
class casa::WrapperBase< T >

Aid in constructing function objects from C++ functions.

Intended use:

Internal

Review Status

Prerequisite

• FunctionWrapper class
• WrapperData class

Synopsis

This base class is provided to enable compile time selection of the appropriate function call through WrapperData.

Example

    Float func(const Vector<Float>& x) { return x(0)*x(1); }        // x*y
    // Convert C++ functions to Functionals
    FunctionWrapper<Float> Func(func, 2);
