Class DataSource

java.lang.Object
  atg.nucleus.logging.VariableArgumentApplicationLoggingImpl
      atg.nucleus.GenericService
          atg.service.datacollection.DataSource

All Implemented Interfaces:

atg.naming.AbsoluteNameable, NameContextBindingListener, NameContextElement, atg.naming.NameContextParentable, NameResolver, AdminableService, atg.nucleus.Configured, ApplicationLogging, atg.nucleus.logging.ApplicationLoggingSender, atg.nucleus.logging.TraceApplicationLogging, VariableArgumentApplicationLogging, ComponentNameResolver, Service, ServiceListener, java.util.EventListener

public class DataSource
extends GenericService

Sample data source implementation. To be a data source, you can:

1. subclass DataSource
2. encapsulate DataSource (i.e., declare a DataSource object in your object and pass through the DataListener method calls
3. implement the DataListener calls yourself
4. if you are a GenericService, and your datapoints are LogEvents, and you don't feel like writing code you can just call sendLogEvent

This class is not used by the data collection package. DataSource serves as a sample of the design pattern to follow to be source of data items. The GenericSummarizer is also a source of data items, and implements the relevant DataListener calls itself.
