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.
Initializers
import com.aliyun.ros.cdk.ros.WaitConditionHandle;
WaitConditionHandle.Builder.create(Construct scope, java.lang.String id, java.lang.Boolean enableResourcePropertyConstraint)
// .count(java.lang.Number)
// .count(IResolvable)

count |
java.lang.Number OR com.aliyun.ros.cdk.core.IResolvable |
Property count: There are 3 preconditions that make Count taking effect: 1.Mode is set to Full. 2.Count >= 0. 3.The id of signal is not specified. If so, it will be a self-increasing integer started from 1. For example, the id of the first signal is 1, the id of the second signal is 2, and so on. |
mode |
java.lang.String OR com.aliyun.ros.cdk.core.IResolvable |
Property mode: If set to Increment, all old signals will be deleted before update. |
scope
Required
- Type: com.aliyun.ros.cdk.core.Construct
id
Required
- Type: java.lang.String
enableResourcePropertyConstraint
Optional
- Type: java.lang.Boolean
count
Optional
- Type: java.lang.Number OR com.aliyun.ros.cdk.core.IResolvable
Property count: There are 3 preconditions that make Count taking effect: 1.Mode is set to Full. 2.Count >= 0. 3.The id of signal is not specified. If so, it will be a self-increasing integer started from 1. For example, the id of the first signal is 1, the id of the second signal is 2, and so on.
If Count takes effect, signals with id > Count will be deleted before update. The default value is -1, which means no effect. It is recommended to quote the same value with WaitCondition.Count.
mode
Optional
- Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable
Property mode: If set to Increment, all old signals will be deleted before update.
In this mode, WaitCondition.Count should reference an incremental value instead of a full value, such as ScalingGroupEnable.ScalingRuleArisExecuteResultNumberOfAddedInstances.
If set to Full, no old signal will be deleted unless Count is set. In this mode, WaitCondition.Count should reference a full value, such as the same value with InstanceGroup.MaxAmount. It is recommended to use this mode with Count.
Default to Full.

toString
public java.lang.String toString()
Returns a string representation of this construct.
synthesize
public void synthesize(ISynthesisSession session)
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.
- Type: com.aliyun.ros.cdk.core.ISynthesisSession
The synthesis session.
addCondition
public void addCondition(RosCondition condition)
- Type: com.aliyun.ros.cdk.core.RosCondition
addCount
public void addCount(java.lang.Number OR IResolvable count)
- Type: java.lang.Number OR com.aliyun.ros.cdk.core.IResolvable
addDependency
public void addDependency(Resource resource)
- Type: com.aliyun.ros.cdk.core.Resource
addResourceDesc
public void addResourceDesc(java.lang.String desc)
- Type: java.lang.String
applyRemovalPolicy
public void applyRemovalPolicy(RemovalPolicy policy)
- Type: com.aliyun.ros.cdk.core.RemovalPolicy
getAtt
public IResolvable getAtt(java.lang.String name)
- Type: java.lang.String
setMetadata
public void setMetadata(java.lang.String key, java.lang.Object value)
- Type: java.lang.String
- Type: java.lang.Object
Static Functions
Name | Description |

node
Required
public ConstructNode getNode();
- Type: com.aliyun.ros.cdk.core.ConstructNode
The construct tree node associated with this construct.
ref
Required
public java.lang.String getRef();
- Type: java.lang.String

Required
public Stack getStack();
- Type: com.aliyun.ros.cdk.core.Stack

Optional
public RosResource getResource();
- Type: com.aliyun.ros.cdk.core.RosResource
attrCurlCli
Required
public IResolvable getAttrCurlCli();
- Type: com.aliyun.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 IResolvable getAttrHeaders();
- Type: com.aliyun.ros.cdk.core.IResolvable
Attribute Headers: HTTP POST Headers used for signalling handle completion or failure.
attrPowerShellCurlCli
Required
public IResolvable getAttrPowerShellCurlCli();
- Type: com.aliyun.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 IResolvable getAttrUrl();

attrWindowsCurlCli
Required
public IResolvable getAttrWindowsCurlCli();
- Type: com.aliyun.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"}"
