Detailed Description

Function Documentation

filter()

template<typename T , typename F >

unsigned int filter	(	const F &	func,
		const T &	container,
		T &	ret )

Filter given container by calling func on each element. If func returns true for given element, it will be copied to other list.

for_each() [1/2]

template<typename T , typename F >

void for_each	(	const F &	func,
		const T &	container )

Traverse container calling func on each element. Returns nothing.

for_each() [2/2]

template<typename T , typename F >

void for_each	(	const F &	func,
		const T &	container,
		void *	p )

Same as above for_each, but with additional void* parameter that is given to function as second parameter (function is called as func(val, void*)

References edelib::for_each().

map()

template<typename T , typename F >

void map	(	F &	func,
		const T &	container,
		T &	ret )

Apply func on each element of given container and add it to ret container.

reduce()

template<typename T , typename R , typename F >

void reduce	(	F &	func,
		const T &	container,
		R &	ret )

Reduce all elements from container using func as function. The best example of this is to sum all elements, like:

int sum(int a, int b) {
   return a + b;
}
 
int ret;
list <int> lst; // [1,2,3,4,5]
reduce(sum, lst, ret);
// result will be in form 1 + 2 + 3 + 4 + 5
