- Method Detail
  - getJobId
```
java.lang.String getJobId()
```
    Get the runtime identifier for this container's running job. In distributed mode the identifier will be job identifier of the submitted application. When not in distributed mode the identifier is 0.
    
    Returns:
    
    The job identifier for the current application.
  - getId
```
java.lang.String getId()
```
    Get the runtime identifier for this container. In distributed mode the identifier will be processing element (PE) identifier of the process executing the function. When not in distributed mode the identifier is 0.
    
    Returns:
    
    The identifier for this container.
  - getDomainId
```
java.lang.String getDomainId()
```
    Return the IBM Streams domain identifier for this container. In distributed mode the domain identifier will be that of the IBM Streams domain running the application. When not in distributed mode this will be the current operating system user identifier.
    
    Returns:
    
    Domain identifier for this container or the user identifier.
  - getInstanceId
```
java.lang.String getInstanceId()
```
    Return the IBM Streams instance identifier for this container. In distributed mode the instance identifier will be that of the IBM Streams instance running the application. When not in distributed mode this will be the current operating system user identifier.
    
    Returns:
    
    Instance identifier for this container or the user identifier.
  - getRelaunchCount
```
int getRelaunchCount()
```
    Return the number of times this container has been relaunched. For the first execution, the value will be 0.
    
    Returns:
    
    number of times this container has been relaunched.
  - getConfiguredHost
```
java.net.InetAddress getConfiguredHost()
                                throws java.net.UnknownHostException
```
    Get the host this container is executing on.
    When running in distributed mode this returns the InetAddress for the interface configured for application use by the IBM Streams instance. This may differ from from java.net.InetAddress.getLocalHost() if there are multiple network interfaces on this host.
    
    When not running in distributed, this returns java.net.InetAddress.getLocalHost().
    
    Returns:
    
    Host this container is executing on
    
    Throws:
    
    java.net.UnknownHostException
