params_ref::find (2 of 2 overloads)

(Inherited from params_base)

Find a matching key.

Synopsis
iterator
find(
    iterator from,
    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 at from and proceeds forward until either the key is found or the end of the range is reached, in which case end() is returned.

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

assert( u.params().find( "first" ) != u.params().find( "first", ignore_case ) );
Complexity

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

Return Value

an iterator to the param

Parameters

Name

Description

from

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.
