scope^Required

• Type: ros_cdk_core.Construct

---

id^Required

• Type: str

---

values^Required

• Type: typing.Union[typing.List[typing.Any], ros_cdk_core.IResolvable]

Property values: A list of values to assert.

The items in the list are compared in order. The range of length is one to three.

• Three values are supported only if the operation is Equal or NotEqual.
• One value is supported only if the operation is Not.

---

abort_creation^Optional

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

Property abortCreation: Whether to abort creation when the assert fails.

Default is True.

---

error_message^Optional

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

Property errorMessage: The error message to be returned when the assert fails.

---

operation^Optional

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

Property operation: The type of assertion to make.

The supported operations are: Equal, NotEqual, Greater, GreaterOrEqual, Less, LessOrEqual, Contain, NotContain, And, Or, Not. Default is Equal.

---

enable_resource_property_constraint^Optional

• Type: bool

Methods

Name	Description
to_string	Returns a string representation of this construct.
synthesize	Allows this construct to emit artifacts into the cloud assembly during synthesis.
add_condition	No description.
add_count	No description.
add_dependency	No description.
add_resource_desc	No description.
apply_removal_policy	No description.
get_att	No description.
set_metadata	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.Assert.is_construct(
  x: typing.Any
)

Return whether the given object is a Construct.

x^Required

• Type: typing.Any

---
