Public Class Methods

WIN32OLE::Method.new(ole_type, method) → WIN32OLE::Method object

Returns a new WIN32OLE::Method object which represents the information about OLE method. The first argument ole_type specifies WIN32OLE::Type object. The second argument method specifies OLE method name defined OLE class which represents WIN32OLE::Type object.
