      de.fhg.igd.atlas.core.AtlasSetup

All Implemented Interfaces:

AgentFilter, Service

public class AtlasSetup

extends AbstractService

implements AgentFilter

This setup filter must be registered under the path of the AgentLauncher. Typically, WhatIs:AGENT_LAUNCHER is the path prefix.

Its task is to automatically register locally started agents within the ATLAS agent tracer. This setup filter relies on a number of additional services that must be present in the Environment.

${WhatIs:AGENT_TRACER}, de.fhg.igd.atlas.core.AgentTracer

The agent tracer maintains a list of agents that were created by the local server. The whereabouts of these agents are tracked automatically by means of Atlas, if Atlas is installed and running.

Within the launching filter pipeline, this filter has to be invoked after the de.fhg.igd.semoa.securityOwnerSetup filter.
