Semicolon after curly braces in C ++

I recently started working with the vtk package, and I see this odd notation that they include ;after closing curly braces }. Here is an example fromvtkUnstructuredGrid.h

// Description:
// Standard vtkDataSet API methods. See vtkDataSet for more information.
int GetDataObjectType() {return VTK_UNSTRUCTURED_GRID;};

It is not needed, and QtCreator also correctly defines this, saying extra ;when parsing the code. I'm curious what could be causing this? Maybe readability?

As QtCreator correctly defines, this is definitely an optional semicolon that is not only useless, but can also cause compiler warnings and confusion.

For example, a GCC with a flag -Wpedantic will run :

warning: extra ';'

. ++ ;. int GetDataObjectType();. , : int GetDataObjectType() {}; , : return VTK_UNSTRUCTURED_GRID;, , , , .
