Insert params

Synopsis

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

iterator
insert(
    iterator before,
    std::initializer_list<param_pct_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.

Note
 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. Exceptions thrown on invalid input.

Exceptions

Name Thrown on

system_error

init contains an invalid percent-encoding.

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.
