Detailed Description

template<typename IN, typename OUT>
class sensesp::Typecast< IN, OUT >

Converts input from one data type to another, then outputs the new type.

To use Typecast, simply construct a new instance of Typecast.

If the data type of IN is capable of doing a typecast to OUT on its own (i.e. C++ has an implicit conversion available, or IN defines a overloaded typecast operator for OUT), then no additional work is needed.

If a compiler-derived typecast from IN to OUT does not exist (or is not the functionality you are looking for), then you must pass in a lambda expression that is capable of doing the conversion explicitly.

Template Parameters

The	data type of input.
The	data type of output.
