Get handle of (non graphics) object

Getting the handle of a figure can be done like this, among others:

hFigure = findall(groot, 'Type', 'Figure');

Let's say I have a class defined like this:

classdef BasicHandle < handle    
    properties
        Prop1
    end    
    methods
        % Constructor
        function obj = BasicHandle(val)
            if nargin > 0
                obj.Prop1 = val;
            end
        end
    end    
end

Is it possible to find all objects of class 'BasicHandle', by using a similar method as findall?

Something like:

hBasic = getHandle('Class', 'BasicHandle');

The only way I can think of to implement something like that is using persistent variables, like in the classdef below. The workflow would then be like this,

>> obj1=BasicHandle(1);
>> obj2=BasicHandle(2);
>> H=BasicHandle.getHandles

H = 

  1×2 BasicHandle array with properties:

    Prop1

>> BasicHandle.clearHandles;

classdef BasicHandle < handle    
    properties
        Prop1
    end    
    methods
        % Constructor
        function obj = BasicHandle(val)
            if nargin > 0
                obj.Prop1 = val;
                recHandles(obj)
            end
        end
    end
    methods (Static)
        function h=getHandles
            h=recHandles;
        end
        
        function clearHandles
           recHandles; 
        end
    end    
end

function objs=recHandles(obj)

  persistent allHandles
  
  if nargin
     allHandles{end+1}=obj; 
  elseif nargout
    if ~isempty(allHandles)
        objs=[allHandles{:}];
    else
        objs=allHandles;
    end
  else
      allHandles=[];
  end


end
