boost::urls::segments_encoded_ref::insert

Insert segments

Synopsis

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

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

Description

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

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. 
std::is_convertible< std::iterator_traits< FwdIt >::reference_type, pct_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. 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 before if init.empty().

Parameters

Name Description

before

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

first

The first element in the range to insert.

last

One past the last element in the range to insert.
