D14956: avoid any heap allocation for default constructed Format() as used as "invalid"

[Christoph Cullmann]

cullmann added a comment.


  Just for the implementation: Is the static default than just a e.g. function 
static QExplicitlySharedDataPointer<FormatPrivate>(new FormatPrivate()) like:
  
  QExplicitlySharedDataPointer<FormatPrivate> &staticDefault()
  {
  
    static QExplicitlySharedDataPointer<FormatPrivate> default(new 
FormatPrivate());
    return default;
  
  }
  
  and the constructor will do
  
  Format::Format() : d(staticDefault())
  {
  }
  
  or is that some other trick?
