## C Specification

Possible values of VkDataGraphPipelineNodeConnectionTypeARM, specifying the connection points of a data graph pipeline node, are:

    // Provided by VK_ARM_data_graph_optical_flow
    typedef enum VkDataGraphPipelineNodeConnectionTypeARM {
      // Provided by VK_ARM_data_graph_optical_flow
        VK_DATA_GRAPH_PIPELINE_NODE_CONNECTION_TYPE_OPTICAL_FLOW_INPUT_ARM = 1000631000,
      // Provided by VK_ARM_data_graph_optical_flow
        VK_DATA_GRAPH_PIPELINE_NODE_CONNECTION_TYPE_OPTICAL_FLOW_REFERENCE_ARM = 1000631001,
      // Provided by VK_ARM_data_graph_optical_flow
        VK_DATA_GRAPH_PIPELINE_NODE_CONNECTION_TYPE_OPTICAL_FLOW_HINT_ARM = 1000631002,
      // Provided by VK_ARM_data_graph_optical_flow
        VK_DATA_GRAPH_PIPELINE_NODE_CONNECTION_TYPE_OPTICAL_FLOW_FLOW_VECTOR_ARM = 1000631003,
      // Provided by VK_ARM_data_graph_optical_flow
        VK_DATA_GRAPH_PIPELINE_NODE_CONNECTION_TYPE_OPTICAL_FLOW_COST_ARM = 1000631004,
    } VkDataGraphPipelineNodeConnectionTypeARM;

## Description

- VK_DATA_GRAPH_PIPELINE_NODE_CONNECTION_TYPE_OPTICAL_FLOW_INPUT_ARM specifies the connection point for the input image of an optical flow node.

- VK_DATA_GRAPH_PIPELINE_NODE_CONNECTION_TYPE_OPTICAL_FLOW_REFERENCE_ARM specifies the connection point for the input reference image of an optical flow node.

- VK_DATA_GRAPH_PIPELINE_NODE_CONNECTION_TYPE_OPTICAL_FLOW_HINT_ARM specifies the connection point for the optional external hint flow vector map of an optical flow node.

- VK_DATA_GRAPH_PIPELINE_NODE_CONNECTION_TYPE_OPTICAL_FLOW_FLOW_VECTOR_ARM specifies the connection point for the output flow vector map of an optical flow node.

- VK_DATA_GRAPH_PIPELINE_NODE_CONNECTION_TYPE_OPTICAL_FLOW_COST_ARM specifies the connection point for the optional output cost map of an optical flow node.
