Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`applyUpdater(INDArray gradient, int iteration, int epoch)`	Modify the gradient to be an update.
`T`	`getConfig()`
`Map<String,INDArray>`	`getState()`
`void`	`setState(Map<String,INDArray> stateMap, boolean initialize)`
`void`	`setStateViewArray(INDArray viewArray, long[] gradientShape, char gradientOrder, boolean initialize)`	For the internal updater state (if any): set this to use the provided array.

- Method Detail
  - getConfig
```
T getConfig()
```
  - setState
```
void setState(Map<String,INDArray> stateMap,
              boolean initialize)
```
  - getState
```
Map<String,INDArray> getState()
```
  - setStateViewArray
```
void setStateViewArray(INDArray viewArray,
                       long[] gradientShape,
                       char gradientOrder,
                       boolean initialize)
```
    For the internal updater state (if any): set this to use the provided array. Used during initialization, and when restoring the updater state (after serialization, for example)
    
    Parameters:
    
    viewArray - Array (that is a view of a larger array) to use for the state.
    
    gradientShape -
    
    gradientOrder -
    
    initialize - If true: the updater must initialize the view array. If false: no change to view array contents
  - applyUpdater
```
void applyUpdater(INDArray gradient,
                  int iteration,
                  int epoch)
```
    Modify the gradient to be an update. Note that this is be done in-place
    
    Parameters:
    
    gradient - the gradient to modify
    
    iteration -
