boost::urls::segments_encoded_ref::replace

Replace segments

Synopsis

Declared in header <boost/url/segments_encoded_ref.hpp>

template<class FwdIt>
iterator
replace(
    iterator from,
    iterator to,
    FwdIt first,
    FwdIt last);

Description

This function replaces a range of segments with annother range of segments. Reserved characters in the new range are automatically escaped. Escapes in the new range are preserved.

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

Preconditions

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

Complexity

Linear in std::distance( first, last ) + 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 range 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,

to The range of segments to replace.

first,

last The range of segments to assign.
