ProductTopic

• Implements: IProductTopic

This class encapsulates and extends the ROS resource type ALIYUN::IOT::ProductTopic.

Initializers

import com.aliyun.ros.cdk.iot.ProductTopic;

    .operation(java.lang.String)
    .operation(IResolvable)
    .productKey(java.lang.String)
    .productKey(IResolvable)

    .build();

scope^Required

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

id^Required

• Type: java.lang.String

enableResourcePropertyConstraint^Optional

• Type: java.lang.Boolean

operation^Required

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

Property operation: Operation permissions of devices on the topic category.

Value options: SUB: Subscribe. Devices can subscribe to the topics of this category. PUB: Publish. Devices can publish messages using the topics of this category. ALL: Subscribe and publish. Devices can subscribe to and publish messages to the topics of this category.

productKey^Required

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

Property productKey: The unique identifier of the product for which you want to create a topic category.

topicShortName^Required

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

Property topicShortName: The custom category hierarchy in the topic category.

By default, a topic category contains two system defined category hierarchies: productKey and ${deviceName}. Forward slashes (/) are used to delimit the topic hierarchies. The format of a topic category is productKey/${deviceName}/topicShortName. Note The name of each category hierarchy can contain English letters, digits, and underscores (_), and cannot be empty.

desc^Optional

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

Property desc: The description of the topic category.

You can enter a description with up to 100 characters.

iotInstanceId^Optional

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

Property iotInstanceId: Instance ID you purchased.

Public instances do not need pass this property.

Methods

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.

session^Required

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

The synthesis session.

addCondition

public void addCondition(RosCondition condition)

condition^Required

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

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

applyRemovalPolicy

public void applyRemovalPolicy(RemovalPolicy policy)

policy^Required

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

fetchCondition

public RosCondition fetchCondition()

fetchDependency

public java.util.List<java.lang.String> fetchDependency()

fetchResourceDesc

public java.lang.String fetchResourceDesc()

getAtt

public IResolvable getAtt(java.lang.String name)

name^Required

• Type: java.lang.String

setMetadata

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

key^Required

• Type: java.lang.String

value^Required

• Type: java.lang.Object

Static Functions

isConstruct

import com.aliyun.ros.cdk.iot.ProductTopic;
ProductTopic.isConstruct(java.lang.Object x)

Return whether the given object is a Construct.

x^Required

• Type: java.lang.Object

Properties

node^Required

public ConstructNode getNode();

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

The construct tree node associated with this construct.

env^Required

public IResourceEnvironment getEnv();

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

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

ref^Required

public java.lang.String getRef();

• Type: java.lang.String

stack^Required

public Stack getStack();

• Type: com.aliyun.ros.cdk.core.Stack

The stack in which this resource is defined.

resource^Optional

public RosResource getResource();

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

attrTopicId^Required

public java.lang.Object getAttrTopicId();

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

Attribute TopicId: Topic ID.

props^Required

public ProductTopicProps getProps();

• Type: ProductTopicProps
