Topic

This class encapsulates and extends the ROS resource type ALIYUN::MNS::Topic, which is used to create a topic.

scope^Required

• Type: ros_cdk_core.Construct

---

id^Required

• Type: str

---

---

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

---

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

Name	Description
is_construct	Return whether the given object is a Construct.

---

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
