[heading Description]
|
||
|
|
|
||
|
|
`accumulate` is a generalisation of summation. It computes a binary operation (`operator+`
|
||
|
|
in the non-predicate version) of `init` and all of the elements in `rng`.
|
||
|
|
|
||
|
|
The return value is the resultant value of the above algorithm.
|
||
|
|
|
||
|
|
[heading Definition]
|
||
|
|
|
||
|
|
Defined in the header file `boost/range/numeric.hpp`
|
||
|

||
|
|
[heading Requirements]
|
||
|
|
|
||
|
|
[heading For the first version]
|
||
|
|
|
||
|
|
# `SinglePassRange` is a model of the __single_pass_range__ Concept.
|
||
|
|
# `Value` is a model of the `AssignableConcept`.
|
||
|
|
# An `operator+` is defined for a left-hand operand of type `Value` and a right-hand operand of the `SinglePassRange` value type.
|
||
|
|
# The return type of the above operator is convertible to `Value`.
|
||
|
|
|
||
|
|
[heading For the second version]
|
||
|
|
|
||
|
|
# `SinglePassRange` is a model of the __single_pass_range__ Concept.
|
||
|
|
# `Value` is a model of the `AssignableConcept`.
|
||
|
|
# `BinaryOperation` is a model of the `BinaryFunctionConcept`.
|
||
|
|
# `Value` is convertible to `BinaryOperation`'s first argument type.
|
||
|
|
# `SinglePassRange`'s value type is convertible to `BinaryOperation`'s second argument type.
|
||
|
|
# The return type of `BinaryOperation` is convertible to `Value`.
|
||
|
|
|
||
|
|
[heading Complexity]
|
||
|
|
|
||
|
|
Linear. Exactly `distance(source_rng)`.
