Class Summary

Class	Description
AtomContext	A minimal implementation of BaggageContext based on atoms and lexicographic merge, but providing no read or write methods to the atoms themselves.
AtomContextProvider	BaggageProvider for AtomContext, a minimal BaggageContext based on atoms and lexicographic merge.
AtomContextProviderFactory	BaggageProviderFactory for AtomContextProvider
BaggageHandlerRegistry	BaggageHandlerRegistry manages the mapping of baggage handlers to bag numbers.
BDLContext	The full-featured BaggageContext implementation used by the tracing plane using atoms and the baggage protocol, intended for use in conjunction with BDL-compiled accessor classes.
BDLContextProvider	BaggageProvider for BDLContext, which extends NestedBaggageContext to provide object representations for a range of data types, and to convert to and from those object representations using BDL-generated classes.
BDLContextProviderFactory	BaggageProviderFactory for BDLContextProvider
BDLContextUtils	Helper methods for BDLContext instances -- calculating serialized size, printing context contents, etc.
BDLContextUtils.NullBaggageListener
NestedBaggageContext	An implementation of BaggageContext that interprets atoms using the baggage protocol, which specifies a data layout for nested bags.
NestedBaggageContextProvider	BaggageProvider for NestedBaggageContext, which extends AtomContext to interpret atoms as nested data structures.
NestedBaggageContextProviderFactory	BaggageProviderFactory for NestedBaggageContextProvider
NoOpBaggageContextProvider	A BaggageProvider implementation that always just returns null.
NoOpBaggageContextProviderFactory	A BaggageProvider implementation that always just returns null.
NoOpTransitLayer	A TransitLayer that does nothing.
NoOpTransitLayerFactory	A TransitLayer that does nothing.
ThreadLocalTransitLayer	A straightforward TransitLayer implementation based on thread-local storage.
ThreadLocalTransitLayerFactory	The TransitLayerFactory that creates ThreadLocalTransitLayer instances.

Package brown.tracingplane.impl Description

Implementations of BaggageContext at several different points in the Tracing Plane.

AtomContext is the most lightweight atom-based context, which provides no accessor or convenience methods for manipulating data. AtomContext is purely for propagation (e.g., forwarding baggage contexts that you received from other network calls).

NestedBaggageContext extends the Atom Context and implements the Baggage Protocol, which gives nested data structures.

BDLContext is the full-featured baggage context, which provides interpretations for different data types using atoms.
