- Method Detail
  - getOrderedLayers
```
protected Trainable[] getOrderedLayers()
```
    Specified by:
    
    getOrderedLayers in class BaseMultiLayerUpdater<Layer>
    
    Returns:
    
    Array of layers, in the correct order (i.e., same order as the parameter/gradient/updater flattening order - input to output for MultiLayerNetwork, or topological order for ComputationGraph)
  - getFlattenedGradientsView
```
public INDArray getFlattenedGradientsView()
```
    Specified by:
    
    getFlattenedGradientsView in class BaseMultiLayerUpdater<Layer>
    
    Returns:
    
    The flattened gradient view array for the model
  - getParams
```
protected INDArray getParams()
```
    Specified by:
    
    getParams in class BaseMultiLayerUpdater<Layer>
    
    Returns:
    
    The flattened parameter array for the model
  - isMiniBatch
```
protected boolean isMiniBatch()
```
    Specified by:
    
    isMiniBatch in class BaseMultiLayerUpdater<Layer>
    
    Returns:
    
    True if the configuration for the model is set to minibatch (divide by minibatch size), false otherwise
  - isSingleLayerUpdater
```
protected boolean isSingleLayerUpdater()
```
    Overrides:
    
    isSingleLayerUpdater in class BaseMultiLayerUpdater<Layer>
