Method Summary

All Methods Instance Methods Abstract Methods Deprecated Methods
Modifier and Type	Method	Description
`INDArray`	`dimensions()`	This method returns dimensions for this op
`Number`	`getFinalResult()`
`Op.Type`	`getOpType()`
`boolean`	`isComplexAccumulation()`	Deprecated.
`boolean`	`isKeepDims()`	This method returns TRUE if we're going to keep axis, FALSE otherwise
`INDArray`	`noOp()`	Returns the no op version of the input Basically when a reduce can't happen (eg: sum(0) on a row vector) you have a no op state for a given reduction.
`DataType`	`resultType()`	This method returns datatype for result array wrt given inputs
`DataType`	`resultType(OpContext oc)`
`void`	`setDimensions(int... dimensions)`
`boolean`	`validateDataTypes(OpContext oc)`

- Method Detail
  - noOp
```
INDArray noOp()
```
    Returns the no op version of the input Basically when a reduce can't happen (eg: sum(0) on a row vector) you have a no op state for a given reduction. For most accumulations, this should return x but certain transformations should return say: the absolute value
    
    Returns:
    
    the no op version of the input
  - dimensions
```
INDArray dimensions()
```
    This method returns dimensions for this op
    
    Returns:
  - isComplexAccumulation
```
@Deprecated
boolean isComplexAccumulation()
```
    Deprecated.
  - getOpType
```
Op.Type getOpType()
```
  - isKeepDims
```
boolean isKeepDims()
```
    This method returns TRUE if we're going to keep axis, FALSE otherwise
    
    Returns:
  - resultType
```
DataType resultType()
```
    This method returns datatype for result array wrt given inputs
    
    Returns:
  - resultType
```
DataType resultType(OpContext oc)
```
  - validateDataTypes
```
boolean validateDataTypes(OpContext oc)
```
  - getFinalResult
```
Number getFinalResult()
```
  - setDimensions
```
void setDimensions(int... dimensions)
```
