Interface IWorker

All Superinterfaces:

Runnable

All Known Subinterfaces:

IPrivilegeWorker

Deprecated. You should use processing units and event containers to implement code that is collocated with the space. Please refer to the GigaSpaces XAP documentation for more details: http://www.gigaspaces.com/wiki

@Deprecated
public interface IWorker
extends Runnable

 This interface represents a generic space worker.
 Default public constructor must be defined for every implemented worker.
 On create/init space the init() method will be called.
 On destroy and shutdown space, the close() method will be called.
 
 To setup the IWorker implementation class you need to modify the space schema file - i.e. 
 <GigaSpaces Root>\config\schemas\<Schema Name>-space-schema.xml 
 For example: If you are using the cache schema you should modify the following file:
 <GigaSpaces Root>\config\schemas\cache-space-schema.xml 
  
 If you are using gsInstance to run the space make sure will be part space CLASSPATH. 
 One way to do that is by running gsInstance with the following parameters: 
 gsInstance SPACE_URL CLASSPATH_TO_APPEND
 Example: 
 gsInstance "/./mySpace?schema=cache" "c:\GigaSpacesEE5.0;..\AppLicationClasspath" 
 
 The space schema should have the following defined:
 
 <space-config>
  <workers>
      <worker-names>MonitorWorker, StatisticWorker</worker-names>
      <MonitorWorker>
          <enabled>true</enabled>
          <class-name>test.MonitorWorker</class-name>
          <arg>file:///usr/root/my-monitor-worker-prop.xml</arg>
          <description>Provides Space monitor capabilities</description>
      </MonitorWorker>
      <StatisticWorker>
          <enabled>true</enabled>
          <class-name>test.StatisticWorker</class-name>
          <arg></arg>
          <description></description>
      </StatisticWorker>
  </workers>
 </space-config>
