inlineinherited

Split a string into substrings using a given delimiter.

Returns: T - container with the result.

◆ splitf()

inlineinherited

Split a string into parts at a given delimiter, possibly applying a functor to each substring.

Template Parameters

T	- type of container for folding substrings.

Parameters

delimeter	- substring delimiter.
beforeFunc	- a functor to apply to the found substrings, before placing them in the result.
offset	- the position to start searching for the separator.

Returns: T - result.

For each substring found, if the functor can accept it, the functor is called, and the substring is assigned to the result of the functor. Next, the substring tries to be added to the result, calling one of its methods - emplace_back, push_back, operator[]. If none of this method no, nothing is done, just calling the functor. operator[] tries to apply if the result can have a size via std::size and we do not exceed this size. At the same time, if the found substring turns out to match the entire string, the result is attempted place not a substring, but the entire string object, which allows, for example, to effectively copy sstring.
