iterate()

template<class container_t , class callable_t , class filter_t = decltype(filters::always_true), class adapter_t = decltype(iterate_adapters::no_change)>

void qx::iterate	(	const container_t &	container,
		const callable_t &	callable,
		const filter_t &	filter = filters::always_true,
		const adapter_t &	adapter = iterate_adapters::no_change
	)

Iterate container with filter.

This function is useful when:

1. you don't want to use getter for container (for ex. even const vector of shared_ptr will allow the client to make one more shared_ptr)
2. you don't want the client to know what type of container you are using
3. you want the client to be able to iterate only over a part of the value of an element of the vector

   Template Parameters

   container_t	- container of elements type
   callable_t	- callable type. if callable returns false, iteration breaks
   filter_t	- filter type. if filter returns true, callable is applied
   adapter_t	- adapter type. converts container element type to another type for callable and filter

   Parameters

   container	- container object
   callable	- callable object
   filter	- filter object
   adapter	- adapter object
