InteractionProvider

Provides the current thread’s Interaction .

An Interaction contains a top-level Execution representing the invocation of an action or the editing of a property. If that top-level action or property uses the org.apache.causeway.applib.services.wrapper.WrapperFactory domain service to invoke child actions/properties, then those sub-executions are captured as a call-graph. The Execution is thus a graph structure.
