accumulate
Description

Returns the result type of accumulate.

Synopsis
template<
    typename Sequence,
    typename State,
    typename F>
struct accumulate
{
    typedef unspecified type;
};

Table 1.48. Parameters

Parameter

Requirement

Description

Sequence

A model of Forward Sequence

The sequence to iterate

State

Any type

The initial state for the first application of F

F

boost::result_of<F(S,E)>::type is the return type of f(s,e) with current state s of type S, and an element e of type E in seq

The operation to be applied on traversal


Expression Semantics
accumulate<Sequence, State, F>::type

Return type: Any type

Semantics: Returns the result of applying accumulate to a sequence of type Sequence, with an initial state of type State and binary function object or function pointer of type F.

Complexity

Linear, exactly result_of::size<Sequence>::value applications of F.
