WaitCondition

This class encapsulates and extends the ROS resource type ALIYUN::ROS::WaitCondition, which is used to wait for signals.

You can use ALIYUN::ROS::WaitCondition together with ALIYUN::ROS::WaitConditionHandle to manage the execution process of a stack. When you create an Elastic Compute Service (ECS) instance, a signal is sent during the execution of the user data.

Initializers

import ros_cdk_ros
ros_cdk_ros.WaitCondition(
  scope: Construct,
  id: str,
  handle: typing.Union[str, IResolvable],
  timeout: typing.Union[typing.Union[int, float], IResolvable],
  count: typing.Union[typing.Union[int, float], IResolvable] = None,
  show_progress_event: typing.Union[str, IResolvable] = None,
  enable_resource_property_constraint: bool = None
)

Name	Type	Description
scope	ros_cdk_core.Construct	No description.
id	str	No description.
handle	typing.Union[str, ros_cdk_core.IResolvable]	Property handle: A reference to the wait condition handle used to signal this wait condition.
timeout	typing.Union[typing.Union[int, float], ros_cdk_core.IResolvable]	Property timeout: The number of seconds to wait for the correct number of signals to arrive.
count	typing.Union[typing.Union[int, float], ros_cdk_core.IResolvable]	Property count: The number of success signals that must be received before the stack creation process continues.
show_progress_event	typing.Union[str, ros_cdk_core.IResolvable]	Property showProgressEvent: Whether to generate progress changed event.
enable_resource_property_constraint	bool	No description.

---

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_ros
ros_cdk_ros.WaitCondition.is_construct(
  x: typing.Any
)

Return whether the given object is a Construct.

x^Required

• Type: typing.Any
