It's actually a singleton, but the API suggests you can create your own or use the default one, but the default one should be the only one.

Comment on attachment 256960 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=256960&action=review > Source/WebCore/ChangeLog:11 > + PasteboardHelper::singleton() and make it non-copiable, fast Nit: non-copyable. > Source/WebCore/platform/gtk/PasteboardHelper.cpp:70 > + gMarkupPrefix = String::fromUTF8("<meta http-equiv=\"content-type\" content=\"text/html; charset=utf-8\">"); Not terribly important since it's only called once, but this string seems ASCII-only, so you could initialize gMarkipPrefix from an ASCIILiteral. Also, can this be initialized where it's declared? > Source/WebCore/platform/gtk/PasteboardHelper.h:38 > + WTF_MAKE_NONCOPYABLE(PasteboardHelper); WTF_MAKE_FAST_ALLOCATED; No need for WTF_MAKE_FAST_ALLOCATED. There's only one object alive during the program's lifetime, and that one is constructed in memory that's reserved by the static NeverDestroyed<PasteboardHelper> object.
