| std::ostream & dtn::data::Block::serialize_strict | ( | std::ostream & | stream | ) | const [protected, virtual] |
Serialize the block in a strict way. Dynamic fields are set to the last deserialized value.
- Parameters:
-
stream the stream to be written into
- Returns:
- the same stream as the parameter for chaining
