find_last

Find a matching key

Synopsis


                iterator
find_last(
    pct_string_view key,
    ignore_case_param ic) noexcept;

Declared in file <boost/url/impl/params_encoded_base.hpp> at line 158

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 from the last param and proceeds backwards until either the key is found or the beginning of the range is reached, in which case `end()` is returned.

Example


assert( url_view( "?first=John&last=Doe" ).encoded_params().find_last( "last" )->value == "Doe" );

Complexity

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

Exception Safety

Exceptions thrown on invalid input.
