org.glassfish.contextpropagation.wireadapters.Catalog

All Implemented Interfaces:

extends Object
implements Serializable

Contains metadata that identifies the each context entry on a stream. This information helps recover from an unrecoverable IO error when reading context-propagation data from a stream. It makes it possible to skip a corrupted context.
