param_pct_view::param_pct_view (4 of 4 overloads)

Construction.

Synopsis

param_pct_view(
    param_view const& p);

This converts a param which may contain unvalidated percent-escapes into a param whose key and value are guaranteed to contain strings with no invalid percent-escapes, otherwise an exception is thrown. 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( param_view( "key" , "value" ) );

Complexity

Linear in key.size() + value.size().

Exception Safety

Exceptions thrown on invalid input.

Exceptions

Type	Thrown On
`system_error`	`key` or `value` contains an invalid percent escape.

Parameters

Name	Description
`p`	The param to construct from.
