Class BaggageHandlerRegistry

java.lang.Object

brown.tracingplane.impl.BaggageHandlerRegistry

public class BaggageHandlerRegistry
extends java.lang.Object

BaggageHandlerRegistry manages the mapping of baggage handlers to bag numbers.

BDL-compiled objects must be registered with a static bag number in order to be used. In concept, this is similar to how protocols get mapped to ports (e.g., SSH maps to port 22, etc.). To register a bag, either specify it as a command line configuration value:

 -Dbag.22=my.compiled.object.MyObject
 

or in your application.conf:

 bag.22 = "my.compiled.object.MyObject"
 

or statically in code:

 BDLContext.register(22, my.compiled.object.MyObject.class);
