- Method Detail
  - getPartitionInfo
```
PartitionInstanceInfo getPartitionInfo()
```
    Returns partition id information for the partition being composed. Most operators should not need to call this method since their output will tend to be a function of the input. This is commonly used for I/O operators which, for example, must chose the output file name based on the partition ID.
    
    Returns:
    
    partition id information for the partition being composed.
  - getNodeAllocation
```
NodeAllocationPlan getNodeAllocation()
```
    Returns the node allocation for the graph to which this operator belongs.
    
    Returns:
    
    the node allocation
  - getDistributedCallableContext
```
DistributedCallableContext getDistributedCallableContext()
```
    Public only as a matter if implementation; operator authors should not invoke this method.
    Returns the distributed callable context in which we are being composed.
    
    Returns:
    
    the distributed context
  - getStatisticsRegistry
```
StatisticsRegistry getStatisticsRegistry()
```
    Public only as a matter of implementation; operator authors should not invoke this method.
    
    Returns:
    
    the statistics registry.
