Properties

Name	Type	Description
env	`ResourceEnvironment`	The environment this resource belongs to.
fifo	`boolean`	Whether this queue is an Amazon SQS FIFO queue.
node	`ConstructNode`	The construct tree node for this construct.
queueArn	`string`	The ARN of this queue.
queueName	`string`	The name of this queue.
queueUrl	`string`	The URL of this queue.
stack	`Stack`	The stack in which this resource is defined.
encryptionMasterKey?	`IKey`	If this queue is server-side encrypted, this is the KMS encryption key.

env

Type: ResourceEnvironment

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

fifo

Type: boolean

Whether this queue is an Amazon SQS FIFO queue.

If false, this is a standard queue.

node

Type: ConstructNode

The construct tree node for this construct.

queueArn

Type: string

The ARN of this queue.

queueName

Type: string

The name of this queue.

queueUrl

Type: string

The URL of this queue.

stack

Type: Stack

The stack in which this resource is defined.

encryptionMasterKey?

Type: IKey (optional)

If this queue is server-side encrypted, this is the KMS encryption key.

addToResourcePolicy(statement)

public addToResourcePolicy(statement: PolicyStatement): AddToResourcePolicyResult

Parameters

statement PolicyStatement

Returns

AddToResourcePolicyResult

Adds a statement to the IAM resource policy associated with this queue.

If this queue was created in this stack (new Queue), a queue policy will be automatically created upon the first call to addToPolicy. If the queue is imported (Queue.import), then this is a no-op.

applyRemovalPolicy(policy)

public applyRemovalPolicy(policy: RemovalPolicy): void

Parameters

policy RemovalPolicy

Apply the given removal policy to this resource.

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).

grant(grantee, ...queueActions)

public grant(grantee: IGrantable, ...queueActions: string[]): Grant

Parameters

grantee IGrantable — Principal to grant right to.
queueActions string — The actions to grant.

Returns

Grant

Grant the actions defined in queueActions to the identity Principal given on this SQS queue resource.

grantConsumeMessages(grantee)

public grantConsumeMessages(grantee: IGrantable): Grant

Parameters

grantee IGrantable — Principal to grant consume rights to.

Returns

Grant

Grant permissions to consume messages from a queue.

This will grant the following permissions:

sqs:GetQueueUrl

grantPurge(grantee)

public grantPurge(grantee: IGrantable): Grant

Parameters

grantee IGrantable — Principal to grant send rights to.

Returns

Grant

Grant an IAM principal permissions to purge all messages from the queue.

This will grant the following permissions:

grantSendMessages(grantee)

public grantSendMessages(grantee: IGrantable): Grant

Parameters

grantee IGrantable — Principal to grant send rights to.

Returns

Grant

Grant access to send messages to a queue to the given identity.

sqs:SendMessage
sqs:GetQueueAttributes
sqs:GetQueueUrl
