count

Return the number of matching keys

Synopsis


                size_t
count(
    string_view key,
    ignore_case_param ic) noexcept;

Declared in file <src/params_base.cpp> at line 190

Description

This function examines the parameters in the container to find the number of matches for the specified key. The comparison is performed as if all escaped characters were decoded first.

Example


assert( url_view( "?first=John&last=Doe" ).params().count( "first" ) == 1 );

Complexity

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

Exception Safety

Throws nothing.
