| /** |
| * A runtime for executing an Edgent streaming org.apache.edgent.org.apache.edgent.topology, designed as an embeddable library |
| * so that it can be executed in a simple Java application. |
| * |
| * <h2>"EveryThing Is An Oplet" (ETIAO)</h2> |
| * |
| * The runtime's focus is on executing oplets and their connected streams, where each |
| * oplet is just a black box. Specifically this means that functionality is added by the introduction |
| * of oplets into the org.apache.edgent.graph that were not explicitly declared by the application developer. |
| * For example, metrics are implemented by oplets, not the runtime. A metric collector is an |
| * oplet that calculates metrics on tuples accepted on its input port, and them makes them |
| * available, for example through JMX. |
