I tried it and it seems typeName from SwgenDefinition() is ignored.

Also how about we add a helper implementation of IDefinition:

type Definition struct {
	TypeName string
	swgen.SchemaObj
}

func (s Definition) SwgenDefinition() (typeName string, typeDef swgen.SchemaObj, err error) {
	typeName = s.TypeName
	typeDef = s.SchemaObj
	return
}

to use in AddTypeMap

g.AddTypeMap(nulltypes.NullTimestamp{}, Definition{TypeName: "MyName", SchemaObj: swgen.SchemaObj{Type: "integer", Format: "int64"}, })
