Insert params

Synopsis

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

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

Description

This function inserts a range of params before the specified position.

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

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

Mandates

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

Complexity

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

Exception Safety

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

Exceptions

system_error

The range contains an invalid percent-encoding.

Return Value

An iterator to the first element inserted, or before if first == last.
