com.goldencode.p2j.convert.db.AstExternalizble

All Implemented Interfaces:

CustomExternalizable, java.io.Externalizable, java.io.Serializable

public class AstExternalizble
extends java.lang.Object
implements CustomExternalizable

For AST values for a db-backed collection, this allows the serialization to the database.

Only the AST ID will be stored.
