AWS IoT Things Graph Construct Library

This module is part of the AWS Cloud Development Kit project.

import iotthingsgraph "github.com/aws/aws-cdk-go/awscdk"

There are no official hand-written (L2) constructs for this service yet. Here are some suggestions on how to proceed:

• Search Construct Hub for IoTThingsGraph construct libraries
• Use the automatically generated L1 constructs, in the same way you would use the CloudFormation AWS::IoTThingsGraph resources directly.

There are no hand-written (L2) constructs for this service yet. However, you can still use the automatically generated L1 constructs, and use this service exactly as you would using CloudFormation directly.

For more information on the resources and properties available for this service, see the CloudFormation documentation for AWS::IoTThingsGraph.

(Read the CDK Contributing Guide and submit an RFC if you are interested in contributing to this construct library.)

Functions

func CfnFlowTemplate_CFN_RESOURCE_TYPE_NAME

func CfnFlowTemplate_CFN_RESOURCE_TYPE_NAME() *string

func CfnFlowTemplate_IsCfnElement

func CfnFlowTemplate_IsCfnElement(x interface{}) *bool

Returns `true` if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of `instanceof` to allow stack elements from different versions of this library to be included in the same stack.

Returns: The construct as a stack element or undefined if it is not a stack element.

func CfnFlowTemplate_IsCfnResource

func CfnFlowTemplate_IsCfnResource(construct constructs.IConstruct) *bool

Check whether the given construct is a CfnResource.

func CfnFlowTemplate_IsConstruct

func CfnFlowTemplate_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

func NewCfnFlowTemplate_Override

func NewCfnFlowTemplate_Override(c CfnFlowTemplate, scope constructs.Construct, id *string, props *CfnFlowTemplateProps)

Create a new `AWS::IoTThingsGraph::FlowTemplate`.

Types

	awscdk.CfnResource
	awscdk.IInspectable
	// Options for this resource, such as condition, update policy etc.
	CfnOptions() awscdk.ICfnResourceOptions
	CfnProperties() *map[string]interface{}
	// AWS resource type.
	CfnResourceType() *string
	// The version of the user's namespace against which the workflow was validated.
	//
	// Use this value in your system instance.
	CompatibleNamespaceVersion() *float64
	SetCompatibleNamespaceVersion(val *float64)
	// Returns: the stack trace of the point where this Resource was created from, sourced
	// from the +metadata+ entry typed +aws:cdk:logicalId+, and with the bottom-most
	// node +internal+ entries filtered.
	CreationStack() *[]*string
	// A workflow's definition document.
	Definition() interface{}
	SetDefinition(val interface{})
	// The logical ID for this CloudFormation stack element.
	//
	// The logical ID of the element
	// is calculated from the path of the resource node in the construct tree.
	//
	// To override this value, use `overrideLogicalId(newLogicalId)`.
	//
	// Returns: the logical ID as a stringified token. This value will only get
	// resolved during synthesis.
	LogicalId() *string
	// The tree node.
	Node() constructs.Node
	// Return a string that will be resolved to a CloudFormation `{ Ref }` for this element.
	//
	// If, by any chance, the intrinsic reference of a resource is not a string, you could
	// coerce it to an IResolvable through `Lazy.any({ produce: resource.ref })`.
	Ref() *string
	// The stack in which this element is defined.
	//
	// CfnElements must be defined within a stack scope (directly or indirectly).
	Stack() awscdk.Stack
	// Deprecated.
	// Deprecated: use `updatedProperties`
	//
	// Return properties modified after initiation
	//
	// Resources that expose mutable properties should override this function to
	// collect and return the properties object for this resource.
	UpdatedProperites() *map[string]interface{}
	// Return properties modified after initiation.
	//
	// Resources that expose mutable properties should override this function to
	// collect and return the properties object for this resource.
	UpdatedProperties() *map[string]interface{}
	// Syntactic sugar for `addOverride(path, undefined)`.
	AddDeletionOverride(path *string)
	// Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
	//
	// This can be used for resources across stacks (or nested stack) boundaries
	// and the dependency will automatically be transferred to the relevant scope.
	AddDependsOn(target awscdk.CfnResource)
	// Add a value to the CloudFormation Resource Metadata.
	// See: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html
	//
	// Note that this is a different set of metadata from CDK node metadata; this
	// metadata ends up in the stack template under the resource, whereas CDK
	// node metadata ends up in the Cloud Assembly.
	//
	AddMetadata(key *string, value interface{})
	// Adds an override to the synthesized CloudFormation resource.
	//
	// To add a
	// property override, either use `addPropertyOverride` or prefix `path` with
	// "Properties." (i.e. `Properties.TopicName`).
	//
	// If the override is nested, separate each nested level using a dot (.) in the path parameter.
	// If there is an array as part of the nesting, specify the index in the path.
	//
	// To include a literal `.` in the property name, prefix with a `\`. In most
	// programming languages you will need to write this as `"\\."` because the
	// `\` itself will need to be escaped.
	//
	// For example,
	// “`typescript
	// cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
	// cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');
	// “`
	// would add the overrides
	// “`json
	// "Properties": {
	//    "GlobalSecondaryIndexes": [
	//      {
	//        "Projection": {
	//          "NonKeyAttributes": [ "myattribute" ]
	//          ...
	//        }

	//        "ProjectionType": "INCLUDE"
	//        ...
	//      },
	//    ]
	//    ...
	// }
	// “`
	//
	// The `value` argument to `addOverride` will not be processed or translated
	// in any way. Pass raw JSON values in here with the correct capitalization
	// for CloudFormation. If you pass CDK classes or structs, they will be
	// rendered with lowercased key names, and CloudFormation will reject the
	// template.
	AddOverride(path *string, value interface{})
	// Adds an override that deletes the value of a property from the resource definition.
	AddPropertyDeletionOverride(propertyPath *string)
	// Adds an override to a resource property.
	//
	// Syntactic sugar for `addOverride("Properties.<...>", value)`.
	AddPropertyOverride(propertyPath *string, value interface{})
	// Sets the deletion policy of the resource based on the removal policy specified.
	//
	// The Removal Policy controls what happens to this resource when it stops
	// being managed by CloudFormation, either because you've removed it from the
	// CDK application or because you've made a change that requires the resource
	// to be replaced.
	//
	// The resource can be deleted (`RemovalPolicy.DESTROY`), or left in your AWS
	// account for data recovery and cleanup later (`RemovalPolicy.RETAIN`). In some
	// cases, a snapshot can be taken of the resource prior to deletion
	// (`RemovalPolicy.SNAPSHOT`). A list of resources that support this policy
	// can be found in the following link:.
	// See: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html#aws-attribute-deletionpolicy-options
	//
	ApplyRemovalPolicy(policy awscdk.RemovalPolicy, options *awscdk.RemovalPolicyOptions)
	// Returns a token for an runtime attribute of this resource.
	//
	// Ideally, use generated attribute accessors (e.g. `resource.arn`), but this can be used for future compatibility
	// in case there is no generated attribute.
	GetAtt(attributeName *string) awscdk.Reference
	// Retrieve a value value from the CloudFormation Resource Metadata.
	// See: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

	//
	GetMetadata(key *string) interface{}
	// Examines the CloudFormation resource and discloses attributes.
	Inspect(inspector awscdk.TreeInspector)
	// Overrides the auto-generated logical ID with a specific ID.
	OverrideLogicalId(newLogicalId *string)
	RenderProperties(props *map[string]interface{}) *map[string]interface{}
	// Can be overridden by subclasses to determine if this resource will be rendered into the cloudformation template.
	//
	// Returns: `true` if the resource should be included or `false` is the resource
	// should be omitted.
	ShouldSynthesize() *bool

A CloudFormation `AWS::IoTThingsGraph::FlowTemplate`.

Represents a workflow template. Workflows can be created only in the user's namespace. (The public namespace contains only entities.) The workflow can contain only entities in the specified namespace. The workflow is validated against the entities in the latest version of the user's namespace unless another namespace version is specified in the request.

Example:

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

cfnFlowTemplate := awscdk.Aws_iotthingsgraph.NewCfnFlowTemplate(this, jsii.String("MyCfnFlowTemplate"), &cfnFlowTemplateProps{
	definition: &definitionDocumentProperty{
		language: jsii.String("language"),
		text: jsii.String("text"),
	},

	// the properties below are optional
	compatibleNamespaceVersion: jsii.Number(123),
})

func NewCfnFlowTemplate

func NewCfnFlowTemplate(scope constructs.Construct, id *string, props *CfnFlowTemplateProps) CfnFlowTemplate

Create a new `AWS::IoTThingsGraph::FlowTemplate`.

type CfnFlowTemplateProps

type CfnFlowTemplateProps struct {
	// A workflow's definition document.
	Definition interface{} `field:"required" json:"definition" yaml:"definition"`
	// The version of the user's namespace against which the workflow was validated.
	//
	// Use this value in your system instance.
	CompatibleNamespaceVersion *float64 `field:"optional" json:"compatibleNamespaceVersion" yaml:"compatibleNamespaceVersion"`
}

Properties for defining a `CfnFlowTemplate`.

Example:

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

cfnFlowTemplateProps := &cfnFlowTemplateProps{
	definition: &definitionDocumentProperty{
		language: jsii.String("language"),
		text: jsii.String("text"),
	},

	// the properties below are optional
	compatibleNamespaceVersion: jsii.Number(123),
}

type CfnFlowTemplate_DefinitionDocumentProperty

type CfnFlowTemplate_DefinitionDocumentProperty struct {
	// The language used to define the entity.
	//
	// `GRAPHQL` is the only valid value.
	Language *string `field:"required" json:"language" yaml:"language"`
	// The GraphQL text that defines the entity.
	Text *string `field:"required" json:"text" yaml:"text"`
}

A document that defines an entity.

Example:

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

definitionDocumentProperty := &definitionDocumentProperty{
	language: jsii.String("language"),
