write
Description copied from interface:TypeIO
Write a value out to the given byte buffer
-
read
Description copied from interface:TypeIO
Read a value from the given byte buffer
-
unwrap
- Returns:
- a
List
of all the types that are wrapped by this type, including this one, in depth-first-search order. This will mean the simple unwrapped type is the first element of the list.
