question: public Builder rootSourceSectionEquals ( SourceSection ... section ) { verifyNotNull ( section ) ; expressions . add ( new EventFilterExpression . RootSourceSectionEquals ( section ) ) ; return this ; }
target:  Add a filter for all root sources sections that equal one of the given source sections. All descendant source sections of a matching root source section are included in the filter. This can mean in the dynamic language domain that all nodes of a function for which the root source section matches the given source section is instrumented but its inner functions and its nodes are not instrumented.
