Function params_ref::insert

Insert elements

Synopsis

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

params_base::iterator
insert(
    params_base::iterator before,
    std::initializer_list<param_view> init);

Description

This function inserts the params in an initializer-list before the specified position.

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

The strings referenced by the inputs must not come from the underlying url, or else the behavior is undefined.

Complexity

Linear in this->url().encoded_query().size().

Exception Safety

Strong guarantee. Calls to allocate may throw.

Return Value

An iterator to the first element inserted, or before if init.size() == 0.

Parameters

Name Description

before

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

init

The list of params to insert.
