Storing ASTNodes within a DB [message #757069]

Hi,

I am wondering if it is possible to serialize a ASTNode, like a MethodDeclaration or Statement, into e.g. a flat file. Due to performance issues I do not like to parse the same compilation units (big number) every time my plug-in is executed.

Has anyone an idea how to realizes this?

Greetings

Andreas

The ASTNode(s) refer to lot of internal data. Hence, it will not be possible
Is there a reason that you need to parse the same compilation units every time?

Don't think this has been tried before :-)

What kind of information are you looking from the AST? I think the
structural info may be still be useful after the serialization -
deserialization process. However, the 'bindings' are likely to be
useless after serialization.

If you don't need the bindings you can also use
ASTParser#setResolvedBindings(false) to improve the performance a bit.
