But I don't understand how I would use take the SchemaFactory from one schema
and convert it to a SchemaFactory in another VM.
{quote}
All SchemaFactories have public( ? ) no-arg constructor so if you have schema
configuration and factory class you can instantiate factory and thus the schema
in a different VM. So your constraint of primitive objects is applied to
SchemaFactory (but not Schema).
Here is an *approximate* API:
{code:java}
interface SchemaConfiguration {
// can be Map<String, Object> or Serializable or something else
ObjectNode config();
// original factory which created this schema
Class<? extends SchemaFactory> factory();
}
interface ConfigurableSchema extends Schema {
SchemaConfiguration config();
}
// internal schema factory
public AutoconfigurableSchemaFactory implements SchemaFactory {
private final SchemaFactory factory;
public static AutoconfigurableSchemaFactory of(SchemaFactory factory) {
return new AutoconfigurableSchemaFactory();
}
public Schema create(
SchemaPlus parentSchema,
String name,
Map<String, Object> operand) {
final SchemaConfiguration copy = new SchemaConfiguration(operand.clone(),
delegate.getClass());
final Schema delegate = factory.create(parentSchema, name, operand);
return new ConfigurableSchema() {
@Override
SchemaConfiguration config() {
return copy;
}
// all other methods are just delegates
public getTableMap() {
return delegate.getTableMap();
}
}
}
}
{code}
