This class encapsulates and extends the ROS resource type ALIYUN::ROCKETMQ::Topic.

Initializers 

import com.aliyun.ros.cdk.rocketmq.Topic;
Topic.Builder.create(Construct scope, java.lang.String id, java.lang.Boolean enableResourcePropertyConstraint)
    .instanceId(java.lang.String)
    .instanceId(IResolvable)
    .messageType(java.lang.Number)
    .messageType(IResolvable)

    .build();
Name Type Description
scope com.aliyun.ros.cdk.core.Construct No description.
id java.lang.String No description.
enableResourcePropertyConstraint java.lang.Boolean No description.
instanceId java.lang.String OR com.aliyun.ros.cdk.core.IResolvable Property instanceId: The ID of the instance.
messageType java.lang.Number OR com.aliyun.ros.cdk.core.IResolvable Property messageType: The type of the message.
topic java.lang.String OR com.aliyun.ros.cdk.core.IResolvable Property topic: The name of the topic you want to create.
remark java.lang.String OR com.aliyun.ros.cdk.core.IResolvable Property remark: The remarks on the request.

scopeRequired

  • Type: com.aliyun.ros.cdk.core.Construct

idRequired

  • Type: java.lang.String

enableResourcePropertyConstraintOptional

  • Type: java.lang.Boolean

instanceIdRequired

  • Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable

Property instanceId: The ID of the instance.

messageTypeRequired

  • Type: java.lang.Number OR com.aliyun.ros.cdk.core.IResolvable

Property messageType: The type of the message.

Valid values: 0: normal message 1: partitionally ordered message 2: globally ordered message 4: transactional message 5: scheduled/delayed message

topicRequired

  • Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable

Property topic: The name of the topic you want to create.

Note: "CID" and "GID" are the reserved fields of a group ID, and they cannot be the start of a topic name. If namespaces are available in the instance for which the topic is created, the topic name must be unique in the instance and can be duplicated across instances. If no namespaces are available in the instance, the topic name must be unique both in the instance and across instances.

remarkOptional

  • Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable

Property remark: The remarks on the request.

This parameter can be left blank.

Methods

Name Description
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 java.lang.String toString()

Returns a string representation of this construct.

synthesize 

public void synthesize(ISynthesisSession session)

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

sessionRequired

  • Type: com.aliyun.ros.cdk.core.ISynthesisSession

The synthesis session.

addCondition 

public void addCondition(RosCondition condition)

conditionRequired

  • Type: com.aliyun.ros.cdk.core.RosCondition

addCount 

public void addCount(java.lang.Number OR IResolvable count)

countRequired

  • Type: java.lang.Number OR com.aliyun.ros.cdk.core.IResolvable

addDependency 

public void addDependency(Resource resource)

resourceRequired

  • Type: com.aliyun.ros.cdk.core.Resource

addResourceDesc 

public void addResourceDesc(java.lang.String desc)

descRequired

  • Type: java.lang.String

applyRemovalPolicy 

public void applyRemovalPolicy(RemovalPolicy policy)

policyRequired

  • Type: com.aliyun.ros.cdk.core.RemovalPolicy

getAtt 

public IResolvable getAtt(java.lang.String name)

nameRequired

  • Type: java.lang.String

setMetadata 

public void setMetadata(java.lang.String key, java.lang.Object value)

keyRequired

  • Type: java.lang.String

valueRequired

  • Type: java.lang.Object

isConstruct 

import com.aliyun.ros.cdk.rocketmq.Topic;
Topic.isConstruct(java.lang.Object x)

Return whether the given object is a Construct.

xRequired

  • Type: java.lang.Object
