WaitConditionHandle

This class encapsulates and extends the ROS resource type ALIYUN::ROS::WaitConditionHandle, which is used to receive signals.

You can use ALIYUN::ROS::WaitConditionHandle together with ALIYUN::ROS::WaitCondition to manage the execution process of a stack. When you create an Elastic Compute Service (ECS) instance, a signal is sent during the execution of the user data.

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

---

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

Name	Description
isConstruct	Return whether the given object is a Construct.

---

isConstruct

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

Return whether the given object is a Construct.

x^Required

• Type: any

---

Properties

Name	Type	Description
node	@alicloud/ros-cdk-core.ConstructNode	The construct tree node associated with this construct.
ref	string	No description.
stack	@alicloud/ros-cdk-core.Stack	The stack in which this resource is defined.
resource	@alicloud/ros-cdk-core.RosResource	No description.
attrCurlCli	@alicloud/ros-cdk-core.IResolvable	Attribute CurlCli: Convenience attribute, provides curl CLI command prefix, which can be used for signalling handle completion or failure.
attrHeaders	@alicloud/ros-cdk-core.IResolvable	Attribute Headers: HTTP POST Headers used for signalling handle completion or failure.
attrPowerShellCurlCli	@alicloud/ros-cdk-core.IResolvable	Attribute PowerShellCurlCli: Convenience attribute, provides curl CLI command prefix for PowerShell, which can be used for signalling handle completion or failure.
attrUrl	@alicloud/ros-cdk-core.IResolvable	Attribute URL: HTTP POST URL used for signalling handle completion or failure.
attrWindowsCurlCli	@alicloud/ros-cdk-core.IResolvable	Attribute WindowsCurlCli: Convenience attribute, provides curl CLI command prefix for Windows, which can be used for signalling handle completion or failure.

---

node^Required

public readonly node: ConstructNode;

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

The construct tree node associated with this construct.

---

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

---

attrCurlCli^Required

public readonly attrCurlCli: IResolvable;

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

Attribute CurlCli: Convenience attribute, provides curl CLI command prefix, which can be used for signalling handle completion or failure.

You can signal success by adding --data-binary '{"status": "SUCCESS"}' , or signal failure by adding --data-binary '{"status": "FAILURE"}'

---

attrHeaders^Required

public readonly attrHeaders: IResolvable;

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

Attribute Headers: HTTP POST Headers used for signalling handle completion or failure.

---

attrPowerShellCurlCli^Required

public readonly attrPowerShellCurlCli: IResolvable;

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

Attribute PowerShellCurlCli: Convenience attribute, provides curl CLI command prefix for PowerShell, which can be used for signalling handle completion or failure.

As this cmdlet was introduced in PowerShell 3.0, ensure the version of PowerShell satisfies the constraint. (Show the version via $PSVersionTable.PSVersion.) You can signal success by adding -Body '{"status": "SUCCESS"}' , or signal failure by adding -Body '{"status": "FAILURE"}'

---

attrUrl^Required

public readonly attrUrl: IResolvable;

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

Attribute URL: HTTP POST URL used for signalling handle completion or failure.

---

attrWindowsCurlCli^Required

public readonly attrWindowsCurlCli: IResolvable;

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

Attribute WindowsCurlCli: Convenience attribute, provides curl CLI command prefix for Windows, which can be used for signalling handle completion or failure.

As Windows does not support curl command, you need to install curl.exe and add it to PATH first. You can signal success by adding --data-binary "{\"status\": \"SUCCESS\"}" , or signal failure by adding --data-binary "{\"status\": \"FAILURE\"}"
