Detailed Description

ranges::views::transform

The transform view takes in a function T -> U and converts an input range of T into an output range of U by calling the function on every element of the input range.

Example

Output

Syntax

auto output_range = input_range | ranges::views::transform(transform_func);

Parameters

transform_func

• Maps an input value to an output value (transform_func(T) -> U)

input_range

• The range of elements to transform
• Reference type: T

output_range

• The range of output values
• Reference type: U
• Value type: decay_t<U>
• This range will have the same category as the input range (excluding contiguous ranges). Contiguous ranges are reduced to random access ranges.
