accumulate

Description

Returns the result type of accumulate.

Synopsis

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

Table 1.36. 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`	A model of binary Polymorphic Function Object	The operation to be applied on forward traversal

Expression Semantics

result_of::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 Polymorphic Function Object of type F.

Complexity

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