new datasource.Topic(scope: Construct, id: string, props: TopicProps, enableResourcePropertyConstraint?: boolean)

scope^Required

• Type: @alicloud/ros-cdk-core.Construct

id^Required

• Type: string

props^Required

• Type: TopicProps

enableResourcePropertyConstraint^Optional

Methods

toString

public toString(): string

Returns a string representation of this construct.

synthesize

public synthesize(session: ISynthesisSession): void

Allows this construct to emit artifacts into the cloud assembly during synthesis.

This method is usually implemented by framework-level constructs such as Stack and Asset as they participate in synthesizing the cloud assembly.

session^Required

• Type: @alicloud/ros-cdk-core.ISynthesisSession

The synthesis session.

addCondition

public addCondition(condition: RosCondition): void

condition^Required

• Type: @alicloud/ros-cdk-core.RosCondition

addCount

public addCount(count: number | IResolvable): void

count^Required

• Type: number | @alicloud/ros-cdk-core.IResolvable

addDependency

public addDependency(resource: Resource): void

resource^Required

• Type: @alicloud/ros-cdk-core.Resource

addResourceDesc

public addResourceDesc(desc: string): void

desc^Required

• Type: string

applyRemovalPolicy

public applyRemovalPolicy(policy: RemovalPolicy): void

policy^Required

• Type: @alicloud/ros-cdk-core.RemovalPolicy

fetchCondition

public fetchCondition(): RosCondition

fetchDependency

public fetchDependency(): string[]

fetchResourceDesc

public fetchResourceDesc(): string

getAtt

public getAtt(name: string): IResolvable

name^Required

• Type: string

setMetadata

public setMetadata(key: string, value: any): void

key^Required

• Type: string

value^Required

• Type: any

Static Functions

isConstruct

import { datasource } from '@alicloud/ros-cdk-rocketmq5'
datasource.Topic.isConstruct(x: any)

Return whether the given object is a Construct.

x^Required

• Type: any

Properties

node^Required

public readonly node: ConstructNode;

• Type: @alicloud/ros-cdk-core.ConstructNode

The construct tree node associated with this construct.

env^Required

public readonly env: IResourceEnvironment;

• Type: @alicloud/ros-cdk-core.IResourceEnvironment

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.

ref^Required

public readonly ref: string;

• Type: string

stack^Required

public readonly stack: Stack;

• Type: @alicloud/ros-cdk-core.Stack

The stack in which this resource is defined.

resource^Optional

public readonly resource: RosResource;

• Type: @alicloud/ros-cdk-core.RosResource

attrCreateTime^Required

public readonly attrCreateTime: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Attribute CreateTime: The time when the topic was created.

attrInstanceId^Required

public readonly attrInstanceId: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Attribute InstanceId: The ID of the RocketMQ instance.

attrMessageType^Required

public readonly attrMessageType: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Attribute MessageType: The message type of the topic.

attrRemark^Required

public readonly attrRemark: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Attribute Remark: The remarks on the topic.

attrStatus^Required

public readonly attrStatus: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Attribute Status: The state of the topic.

attrTopicName^Required

public readonly attrTopicName: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Attribute TopicName: The name of the topic.

attrUpdateTime^Required

public readonly attrUpdateTime: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Attribute UpdateTime: The time when the topic was last updated.

props^Required

public readonly props: TopicProps;

• Type: TopicProps
