Detailed Description
Formal "void" data-type object.
A placeholder for "no data-type". This should be the only object with meta-type set to TYPE_VOID
Member Function Documentation
◆ encode()

virtual |
Encode the data-type to a stream.
Encode a formal description of the data-type as a <type> element. For composite data-types, the description goes down one level, describing the component types only by reference.
- Parameters
-
encoder is the stream encoder
