OrderedEventProcessorResult (Apache Beam 2.61.0)

java.lang.Object
- org.apache.beam.sdk.extensions.ordered.OrderedEventProcessorResult<KeyT,ResultT,EventT>

Type Parameters:

KeyT -

ResultT -

All Implemented Interfaces:

POutput
```
public class OrderedEventProcessorResult<KeyT,ResultT,EventT>
extends java.lang.Object
implements POutput
```
The result of the ordered processing. Three PCollections are returned:
output - the key/value of the mutated states
unprocessedEvents - the key/value of the events that failed to be processed and the failure reason
processingStatuses - the key/value of the status of processing for a particular key
In case of global sequence processing, the result also contains PCollectionView of the latest contiguous sequence range

  - getPipeline
```
public Pipeline getPipeline()
```
    Description copied from interface: POutput
    
    Returns the owning Pipeline of this POutput.
    
    Specified by:
    
    getPipeline in interface POutput
  - expand
```
public java.util.Map<TupleTag<?>,PValue> expand()
```
    Description copied from interface: POutput
    Expands this POutput into a list of its component output PValues.
    - A PValue expands to itself.
    - A tuple or list of PValues (such as PCollectionTuple or PCollectionList) expands to its component PValue PValues.
    Not intended to be invoked directly by user code.
    Specified by:
    
    expand in interface POutput
  - finishSpecifyingOutput
```
public void finishSpecifyingOutput(java.lang.String transformName,
                                   PInput input,
                                   PTransform<?,?> transform)
```
    Description copied from interface: POutput
    
    As part of applying the producing PTransform, finalizes this output to make it ready for being used as an input and for running.
    This includes ensuring that all PCollections have Coders specified or defaulted.
    Automatically invoked whenever this POutput is output, after POutput.finishSpecifyingOutput(String, PInput, PTransform) has been called on each component PValue returned by POutput.expand().
    
    Specified by:
    
    finishSpecifyingOutput in interface POutput
  - processingStatuses
```
public PCollection<KV<KeyT,OrderedProcessingStatus>> processingStatuses()
```
    Returns:
    
    processing status for a particular key. The elements will have the timestamp of the instant the status was emitted.
  - output
```
public PCollection<KV<KeyT,ResultT>> output()
```
    Returns:
    
    processed states keyed by the original key
  - unprocessedEvents
```
public PCollection<KV<KeyT,KV<java.lang.Long,UnprocessedEvent<EventT>>>> unprocessedEvents()
```
  - latestContiguousRange
```
@Nullable
public PCollectionView<ContiguousSequenceRange> latestContiguousRange()
