describe-objects

Description

Gets the object definitions for a set of objects associated with the pipeline. Object definitions are composed of a set of fields that define the properties of the object.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

describe-objects is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: pipelineObjects

Synopsis

  describe-objects
--pipeline-id <value>
--object-ids <value>
[--evaluate-expressions | --no-evaluate-expressions]
[--cli-input-json <value>]
[--starting-token <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--pipeline-id (string)

The ID of the pipeline that contains the object definitions.

--object-ids (list)

The IDs of the pipeline objects that contain the definitions to be described. You can pass as many as 25 identifiers in a single call to describe-objects .

Syntax:

"string" "string" ...

--evaluate-expressions | --no-evaluate-expressions (boolean)

Indicates whether any expressions in the object should be evaluated when the object descriptions are returned.

--cli-input-json (string) Performs service operation based on the JSON marker provided. The JSON marker 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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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.

Output

pipelineObjects -> (list)

An array of object definitions.

(structure)

Contains information about a pipeline object. This can be a logical, physical, or physical attempt pipeline object. The complete set of components of a pipeline defines the pipeline.

id -> (string)

The ID of the object.

name -> (string)

The name of the object.

fields -> (list)

Key-value pairs that define the properties of the object.

(structure)

A key-value pair that describes a property of a pipeline object. The value is specified as either a marker value (StringValue ) or a reference to another object (RefValue ) but not as both.

key -> (string)

The field identifier.

stringValue -> (string)

The field value, expressed as a String.

refValue -> (string)

The field value, expressed as the identifier of another object.

marker -> (string)

The starting point for the next page of results. To view the next page of results, call describe-objects again with this marker value. If the value is null, there are no more results.

hasMoreResults -> (boolean)

Indicates whether there are more results to return.
