count

Return the number of matching keys

Synopsis


                size_t
count(
    pct_string_view key,
    ignore_case_param ic) noexcept;

Declared in file <src/params_encoded_base.cpp> at line 97

Description

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

Example


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

Complexity

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

Exception Safety

Exceptions thrown on invalid input.
