Topic

• Implements: ITopic

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

Initializers

import ros_cdk_mns
ros_cdk_mns.Topic(
  scope: Construct,
  id: str,
  topic_name: typing.Union[str, IResolvable],
  logging_enabled: typing.Union[bool, IResolvable] = None,

)

scope^Required

• Type: ros_cdk_core.Construct

id^Required

• Type: str

topic_name^Required

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property topicName: Topic name.

logging_enabled^Optional

• Type: typing.Union[bool, ros_cdk_core.IResolvable]

Property loggingEnabled: Whether to enable log management.

"true" indicates that log management is enabled, whereas "false" indicates that log management is disabled. The default value is false

maximum_message_size^Optional

• Type: typing.Union[typing.Union[int, float], ros_cdk_core.IResolvable]

Property maximumMessageSize: Maximum body length of a message sent to the topic, in the unit of bytes.

An integer in the range of 1,024 (1 KB) to 65, 536 (64 KB); default value: 65,536 (64 KB).

tags^Optional

• Type: typing.List[TagsProperty]

Property tags: Tags to attach to Topic.

Max support 20 tags to add during create Topic. Each tag with two properties Key and Value, and Key is required.

enable_resource_property_constraint^Optional

• Type: bool

Methods

to_string

def to_string() -> str

Returns a string representation of this construct.

synthesize

def synthesize(
  session: ISynthesisSession
) -> None

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: ros_cdk_core.ISynthesisSession

The synthesis session.

add_condition

def add_condition(
  condition: RosCondition
) -> None

condition^Required

• Type: ros_cdk_core.RosCondition

add_count

def add_count(
  count: typing.Union[typing.Union[int, float], IResolvable]
) -> None

count^Required

• Type: typing.Union[typing.Union[int, float], ros_cdk_core.IResolvable]

add_dependency

def add_dependency(
  resource: Resource
) -> None

resource^Required

• Type: ros_cdk_core.Resource

add_resource_desc

def add_resource_desc(
  desc: str
) -> None

desc^Required

• Type: str

apply_removal_policy

def apply_removal_policy(
  policy: RemovalPolicy
) -> None

policy^Required

• Type: ros_cdk_core.RemovalPolicy

fetch_condition

def fetch_condition() -> RosCondition

fetch_dependency

def fetch_dependency() -> typing.List[str]

fetch_resource_desc

def fetch_resource_desc() -> str

get_att

def get_att(
  name: str
) -> IResolvable

name^Required

• Type: str

set_metadata

def set_metadata(
  key: str,
  value: typing.Any
) -> None

key^Required

• Type: str

value^Required

• Type: typing.Any

Static Functions

is_construct

import ros_cdk_mns
ros_cdk_mns.Topic.is_construct(
  x: typing.Any
)

Return whether the given object is a Construct.

x^Required

• Type: typing.Any

Properties

node^Required

node: ConstructNode

• Type: ros_cdk_core.ConstructNode

The construct tree node associated with this construct.

env^Required

env: IResourceEnvironment

• Type: 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

ref: str

• Type: str

stack^Required

stack: Stack

• Type: ros_cdk_core.Stack

The stack in which this resource is defined.

resource^Optional

resource: RosResource

• Type: ros_cdk_core.RosResource

attr_arn_with_slash^Required

attr_arn_with_slash: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Attribute ARN.WithSlash: The ARN: acs:mns:$region:$accountid:/topics/$topicName.

attr_topic_name^Required

attr_topic_name: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Attribute TopicName: Topic name.

attr_topic_url^Required

attr_topic_url: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Attribute TopicUrl: URL of created topic.

props^Required

props: TopicProps

• Type: TopicProps
