We have a small language implemented with ANTLR 3.2.
We need to transmit a tree through RMI and therefore the tree
needs to be serializable. I am very curious to learn what the
best approach to serializing an ANTLR tree is.
I have noticed that BaseTree or CommonTree are does not
implement Serializable, while, in ANTLR2, BaseAST does implement
Serializable. - What is the rationale behind this?
- Is it "better" (in terms of performance and robustness) to:
(a) rely on the default Java serialization mechanism that uses
the internal representation of the AST nodes to serialize
the AST, or
(b) serialize to a text format and then use an ANTLR parser to
parse that format upon deserialization, or
(c) something clever I haven't thought of?
Thanks! :)
