```
public interface Operation
```
The common interface used by Steps in a pipeline to call various operations. Each instance of an operation in the pipeline is handled by a unique instance of that Operation class.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default void`	`cleanUp()`	Allows the step to clean itself up when removed from the pipeline.
`java.util.List<InputSocket>`	`getInputSockets()`
`java.util.List<OutputSocket>`	`getOutputSockets()`
`void`	`perform()`	Performs this `Operation`.

- Method Detail
  - getInputSockets
```
java.util.List<InputSocket> getInputSockets()
```
    Returns:
    
    A list of sockets for the inputs that the operation expects.
  - getOutputSockets
```
java.util.List<OutputSocket> getOutputSockets()
```
    Returns:
    
    A list of sockets for the outputs that the operation produces.
  - perform
```
void perform()
```
    Performs this Operation.
  - cleanUp
```
default void cleanUp()
```
    Allows the step to clean itself up when removed from the pipeline. This should only be called by Step.setRemoved() to ensure correct synchronization.
