## Public functions

### Capacity

```
TF_MUST_USE_RESULT Attrs tensorflow::ops::FIFOQueue::Attrs::Capacity(
  int64 x
)
```

The upper bound on the number of elements in this queue.


Negative numbers mean no limit.


Defaults to -1

### Container

```
TF_MUST_USE_RESULT Attrs tensorflow::ops::FIFOQueue::Attrs::Container(
  StringPiece x
)
```

If non-empty, this queue is placed in the given container.


Otherwise, a default container is used.


Defaults to ""

### Shapes

```
TF_MUST_USE_RESULT Attrs tensorflow::ops::FIFOQueue::Attrs::Shapes(
  const gtl::ArraySlice< PartialTensorShape > & x
)
```

The shape of each component in a value.


The length of this attr must be either 0 or the same as the length of component_types. If the length of this attr is 0, the shapes of queue elements are not constrained, and only one element may be dequeued at a time.


Defaults to \[\]

### SharedName

```
TF_MUST_USE_RESULT Attrs tensorflow::ops::FIFOQueue::Attrs::SharedName(
  StringPiece x
)
```

If non-empty, this queue will be shared under the given name across multiple sessions.


Defaults to ""
