Interface RequestTrace

All Known Implementing Classes:

DefaultRequestTrace

public interface RequestTrace

A trace of nested requests that are performed by the repository system. This trace information can be used to correlate repository events with higher level operations in the application code that eventually caused the events. A single trace can carry an arbitrary object as data which is meant to describe a request/operation that is currently executed. For call hierarchies within the repository system itself, this data will usually be the *Request object that is currently processed. When invoking methods on the repository system, client code may provide a request trace that has been prepopulated with whatever data is useful for the application to indicate its state for later evaluation when processing the repository events.
