params_ref::find_last (1 of 2 overloads)

(Inherited from params_base)

Find a matching key.

Synopsis
iterator
find_last(
    string_view key,
    ignore_case_param ic = {}) const;
Description

This function examines the parameters in the container to find a match for the specified key. 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" ).params().find_last( "last" )).value == "Doe" );
Complexity

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

Return Value

an iterator to the param

Parameters

Name

Description

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.
