param_pct_view

Constructor

Synopsis


                template<
    class OptionalString>
void
param_pct_view(
    pct_string_view key,
    const OptionalString& value);

Declared in file <boost/url/param.hpp> at line 776

Description

This constructs a parameter with a key and optional value, which may both contain percent escapes.

The new key and value reference the same corresponding underlying character buffers.

Ownership of the buffers is not transferred; the caller is responsible for ensuring that the assigned buffers remain valid until they are no longer referenced.

Example


param_pct_view qp( "key", optional("value") );

Postconditions


this->key.data() == key.data() && this->value->data() == value->data() && this->has_value == true

Complexity

Linear in `key.size() + value->size()`.

Exception Safety

Exceptions thrown on invalid input.
