LoopExtractionPass (Nemo Project 0.4 API)

java.lang.Object
- org.apache.nemo.common.pass.Pass
- - org.apache.nemo.compiler.optimizer.pass.compiletime.CompileTimePass
  - - org.apache.nemo.compiler.optimizer.pass.compiletime.reshaping.ReshapingPass
    - - org.apache.nemo.compiler.optimizer.pass.compiletime.reshaping.LoopExtractionPass

All Implemented Interfaces:

java.util.function.Function<IRDAG,IRDAG>
```
public final class LoopExtractionPass
extends ReshapingPass
```
Pass for extracting and grouping each loops together using the LoopVertex. It first groups loops together, making each iteration into a LoopOperator. Then, it rolls repetitive operators into one root LoopOperator, which contains enough information to produce all other iterative computations.
