find_last

Find a matching key

Synopsis


                iterator
find_last(
    iterator before,
    pct_string_view key,
    ignore_case_param ic) noexcept;

Declared in file <boost/url/impl/params_encoded_base.hpp> at line 170

Description

This function examines the parameters in the container to find a match for the specified key, which may contain percent escapes. The comparison is performed as if all escaped characters were decoded first.

The search starts prior to `before` and proceeds backwards until either the key is found or the beginning of the range is reached, in which case `end()` is returned.

Example


url_view u( "?First=John&Last=Doe" );

assert( u.encoded_params().find_last( "last" ) != u.encoded_params().find_last( "last", ignore_case ) );

Complexity

Linear in `this->buffer().size()`.
