# tensorflow::ops::FIFOQueue

`#include <data_flow_ops.h>`

A queue that produces elements in first-in first-out order.

## Summary

Arguments:

- scope: A [Scope](https://www.tensorflow.org/versions/r1.15/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- component_types: The type of each component in a value.

<br />

Optional attributes (see `https://www.tensorflow.org/versions/r1.15/api_docs/cc/struct/tensorflow/ops/f-i-f-o-queue/attrs#structtensorflow_1_1ops_1_1_f_i_f_o_queue_1_1_attrs`):

- shapes: 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.
- capacity: The upper bound on the number of elements in this queue. Negative numbers mean no limit.
- container: If non-empty, this queue is placed in the given container. Otherwise, a default container is used.
- shared_name: If non-empty, this queue will be shared under the given name across multiple sessions.

<br />

Returns:

- `https://www.tensorflow.org/versions/r1.15/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output`: The handle to the queue.
