Applies sparse addition to individual values or slices in a Variable.

`ref` is a `Tensor` with rank `P` and `indices` is a `Tensor` of rank `Q`.

`indices` must be integer tensor, containing indices into `ref`. It must be shape `[d_0, ..., d_{Q-2}, K]` where `0 < K <= P`.

The innermost dimension of `indices` (with length `K`) corresponds to indices into elements (if `K = P`) or slices (if `K < P`) along the `K`th dimension of `ref`.

`updates` is `Tensor` of rank `Q-1+P-K` with shape:

[d_0, ..., d_{Q-2, ref.shape[K], ..., ref.shape[P-1]]
}
For example, say we want to add 4 scattered elements to a rank-1 tensor to 8 elements. In Python, that addition would look like this:
ref = tf.Variable([1, 2, 3, 4, 5, 6, 7, 8])
indices = tf.constant([[4], [3], [1], [7]])
updates = tf.constant([9, 10, 11, 12])
with tf.Session() as sess:

The resulting update to ref would look like this:

[1, 13, 3, 14, 14, 6, 7, 20]

See `tf.scatter_nd` for more details about how to make updates to slices.

### Public Methods

 Output () Returns the symbolic handle of a tensor. static ScatterNdAdd ( Scope scope, Operand ref, Operand indices, Operand updates, Options... options) Factory method to create a class wrapping a new ScatterNdAdd operation. Output () Same as ref. static ScatterNdAdd.Options (Boolean useLocking)

## Public Methods

#### public Output <T> asOutput ()

Returns the symbolic handle of a tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

#### public static ScatterNdAdd <T> create ( Scope scope, Operand <T> ref, Operand <U> indices, Operand <T> updates, Options... options)

Factory method to create a class wrapping a new ScatterNdAdd operation.

##### Parameters
 scope current scope A mutable Tensor. Should be from a Variable node. A Tensor. Must be one of the following types: int32, int64. A tensor of indices into ref. A Tensor. Must have the same type as ref. A tensor of updated values to add to ref. carries optional attributes values
##### Returns
• a new instance of ScatterNdAdd

#### public Output <T> outputRef ()

Same as ref. Returned as a convenience for operations that want to use the updated values after the update is done.

#### public static ScatterNdAdd.Options useLocking (Boolean useLocking)

##### Parameters
 useLocking An optional bool. Defaults to True. If True, the assignment will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.
