boost::urls::segments_encoded_ref::replace

Replace segments

Synopsis

Declared in <boost/url/segments_encoded_ref.hpp>

iterator
replace(
    iterator from,
    iterator to,
    std::initializer_list<pct_string_view> init);

Description

This function replaces a range of segments with a list of segments in an initializer list. Reserved characters in the list are automatically escaped. Escapes in the list are preserved.

All iterators that are equal to from or come after are invalidated.

Preconditions

None of the character buffers referenced by the list may overlap the character buffer of the underlying url, or else the behavior is undefined.

Complexity

Linear in init.size() + this‐>url().encoded_resouce().size().

Exception Safety

Strong guarantee. Calls to allocate may throw. Exceptions thrown on invalid input.

Exceptions

Name

Thrown on

system_error

The list contains an invalid percent‐encoding.

Return Value

An iterator to the first segment inserted, or one past to if init.size() == 0.

Parameters

Name

Description

from

The first element in the range of segments to replace.

to

One past the last element in the range of segments to replace.

init

The list of segments to assign.
