- Method Detail
  - name
```
public final String name()
```
    The name of the transform node.
    
    Returns:
    
    The name of the transform node.
  - hasInputs
```
public final boolean hasInputs()
```
    For responses, this returns true if the service returned a value for the Inputs property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - inputs
```
public final List<String> inputs()
```
    Specifies the fields and rows to use as inputs for the aggregate transform.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasInputs() method.
    
    Returns:
    
    Specifies the fields and rows to use as inputs for the aggregate transform.
  - hasGroups
```
public final boolean hasGroups()
```
    For responses, this returns true if the service returned a value for the Groups property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - groups
```
public final List<List<String>> groups()
```
    Specifies the fields to group by.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasGroups() method.
    
    Returns:
    
    Specifies the fields to group by.
  - hasAggs
```
public final boolean hasAggs()
```
    For responses, this returns true if the service returned a value for the Aggs property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - aggs
```
public final List<AggregateOperation> aggs()
```
    Specifies the aggregate functions to be performed on specified fields.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAggs() method.
    
    Returns:
    
    Specifies the aggregate functions to be performed on specified fields.
