scope^Required

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

---

id^Required

• Type: java.lang.String

---

enableResourcePropertyConstraint^Optional

• Type: java.lang.Boolean

---

instanceId^Required

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

Property instanceId: The ID of the instance.

---

messageType^Required

• 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

---

topic^Required

• 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.

toString

public java.lang.String toString()

Returns a string representation of this construct.

synthesize

public void synthesize(ISynthesisSession session)

addCount

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

count^Required

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

---

addDependency

public void addDependency(Resource resource)

resource^Required

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

---

addResourceDesc

public void addResourceDesc(java.lang.String desc)

desc^Required

• Type: java.lang.String
