boost::urls::params_encoded_base::find_last

Find a matching key

Synopsis

Declared in <boost/url/params_encoded_base.hpp>

iterator
find_last(
    iterator before,
    pct_string_view key,
    ignore_case_param ic = {}) const noexcept;

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().

Return Value

an iterator to the param

Parameters

Name	Description
before	One past the position to begin the search from. This can be `end()`.
key	The key to match. By default, a case-sensitive comparison is used.
ic	An optional parameter. If the value `ignore_case` is passed here, the comparison is case-insensitive.
