toString Returns a string representation of this construct.
synthesize Allows this construct to emit artifacts into the cloud assembly during synthesis.
addCondition No description.
addCount No description.
addDependency No description.

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.

sessionRequired

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

The synthesis session.


addCondition

public addCondition(condition: RosCondition): void

conditionRequired

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

addCount

public addCount(count: number | IResolvable): void

countRequired

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

addDependency

public addDependency(resource: Resource): void

resourceRequired

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

addResourceDesc

public addResourceDesc(desc: string): void

descRequired

  • Type: string

applyRemovalPolicy

public applyRemovalPolicy(policy: RemovalPolicy): void

policyRequired

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

getAtt

public getAtt(name: string): IResolvable

nameRequired

  • Type: string

setMetadata

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

keyRequired

  • Type: string

valueRequired

  • Type: any

Static Functions

Name Description

isConstruct

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

Return whether the given object is a Construct.

xRequired

  • Type: any
