Function segments_ref::insert

Insert segments

Synopsis

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

template<class FwdIt>
segments_base::iterator
insert(
    segments_base::iterator before,
    FwdIt first,
    FwdIt last);

Description

This function inserts the segments in a range before the specified position. Reserved characters in the list are automatically escaped.

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

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

Mandates

std::is_convertible< std::iterator_traits< FwdIt >::reference_type, core::string_view >::value == true

Complexity

Linear in std::distance( first, last ) + this->url().encoded_resource().size().

Exception Safety

Strong guarantee. Calls to allocate may throw.

Return Value

An iterator to the first segment inserted, or before if init.empty().

Parameters

Name Description

before

An iterator before which the range is inserted. This may be equal to end().

first,

last The range of segments to insert.
