Class InsightManager

fr.paris5.shaman.insight.component.InsightManager

All Implemented Interfaces:

InsightConfigurationConstants, SystemConfigurationConstants

Direct Known Subclasses:

OperationCombinerTest.DummyInsightManager

public class InsightManager

implements SystemConfigurationConstants, InsightConfigurationConstants

Component Manager dedicated to Insight services. Allows different instantiation approaches for having standalone / rmi server / rmi client objects defined from the same configuration file. The reason to not use ExcaliburComponentManager is that it does not allow to configure the factory instantiating Components.
