Constructor
Synopsis
Declared in header <boost/url/param.hpp>
template<class OptionalString>
param(
core::string_view key,
OptionalString const& value);
Description
This constructs a parameter with a key and value.
No validation is performed on the strings. Ownership of the key and value is acquired by making copies.
Example
param qp( "key", "value" );
param qp( "key", optional<core::string_view>("value") );
param qp( "key", boost::none );
param qp( "key", nullptr );
param qp( "key", no_value );
Postconditions
this->key == key && this->value == value && this->has_value == true
Complexity
Linear in key.size() + value.size()
.
Exception Safety
Calls to allocate may throw.
Parameters
Name | Description |
---|---|
key, |
value The key and value to set. |
