template<typename Element>

template<typename ResultType , class Functor , typename ValueType >

ResultType puddle::Range< Element >::accumulate	(	Functor	func,
		ValueType	init = ResultType()
	)		const

Accumulates the results of a functor called on every element.

This function executes the specified functor on every element in the range and the result of previous invocation or the initial value. The functor must implement a function call operator with four parameters. The first parameter is of the ValueType type

• the previous or initial value, the second has the Element type, the third and fourth are booleans indicating the first and the last element in the traversal.

const

Executes a functor on every element in the range.

This function executes the specified functor on every element in this range. The functor must implement a function call operator with three parameters. The first parameter is of the Element type the second and third are booleans indicating the first and the last element in the traversal.
