- Method Detail
  - asContextualTransform
```
default <OP extends DataOperator> ContextualTransformation<OP> asContextualTransform()
```
    Convert this transformation to (operator specific) contextual transform.
    
    Type Parameters:
    
    OP - Operator
    
    Returns:
    
    this transform converted to contextual transform.
    
    Throws:
    
    java.lang.IllegalArgumentException - on errors
  - asElementWiseTransform
```
default ElementWiseTransformation asElementWiseTransform()
```
    Convert this transformation to element wise (stateless).
    
    Returns:
    
    this transform converted to stateless transform
    
    Throws:
    
    java.lang.IllegalArgumentException - on errors
  - enforceNonTransactional
```
default boolean enforceNonTransactional()
```
    Enforce this transaction to be run as non-transactional even if it consumes transactional inputs. This can be used to convert ACID consistency to eventual consistency on output of transactional attribute(s) consumption.
    
    Returns:
    
    true is this transformation is to be run as non-transactional
