  • Properties
  • States
  • Events
  • Actions
  • Capabilities
  • Mappings
  • Devices
  • Device Models
  • Services

This action doesn't return definitions for systems, flows, and deployments.

See 'aws help' for descriptions of global parameters.

Synopsis

  get-entities
--ids <value>
[--namespace-version <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--ids (list)

An array of entity IDs.

The IDs should be in the following format.

urn:tdm:REGION/ACCOUNT ID/default:device:DEVICENAME

Syntax:

"string" "string" ...

--namespace-version (long)

The version of the user's namespace. Defaults to the latest version of the user's namespace.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Examples

To get definitions for entities

The following get-entities example gets a definition for a device model.

aws iotthingsgraph get-entities \
    --ids "urn:tdm:aws/examples:DeviceModel:MotionSensor"

Output:

{
    "descriptions": [
        {
            "id": "urn:tdm:aws/examples:DeviceModel:MotionSensor",
            "type": "DEVICE_MODEL",
            "createdAt": 1559256190.599,
            "definition": {
                "language": "GRAPHQL",
                "text": "##\n# Specification of motion sensor devices interface.\n##\ntype MotionSensor @deviceModel(id: \"urn:tdm:aws/examples:deviceModel:MotionSensor\",\n        capability: \"urn:tdm:aws/examples:capability:MotionSensorCapability\") {ignore:void}"
            }
        }
    ]
}
