---

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.

---

override_logical_id

def override_logical_id(
  new_logical_id: str
) -> None

Overrides the auto-generated logical ID with a specific ID.

new_logical_id^Required

• Type: str

The new logical ID to use for this stack element.

---

add_condition

def add_condition(
  con: RosCondition
) -> None

con^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_deletion_override

def add_deletion_override(
  path: str
) -> None

Syntactic sugar for addOverride(path, undefined).

path^Required

• Type: str

The path of the value to delete.

---

add_depends_on

def add_depends_on(
  target: RosResource
) -> None

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

target^Required

• Type: ros_cdk_core.RosResource

---

add_desc

def add_desc(
  desc: str
) -> None

desc^Required

• Type: str

---

add_meta_data

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

key^Required

• Type: str

---

value^Required

• Type: typing.Any

---

add_override

def add_override(
  path: str,
  value: typing.Any
) -> None

Adds an override to the synthesized ROS resource.

To add a property override, either use addPropertyOverride or prefix path with "Properties." (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

For example,

addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute'])
addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE')

would add the overrides

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

path^Required

• Type: str

The path of the property, you can use dot notation to override values in complex types.

Any intermdediate keys will be created as needed.

---

value^Required

• Type: typing.Any

The value.

Could be primitive or complex.

---

add_property_deletion_override

def add_property_deletion_override(
  property_path: str
) -> None

The path to the property.

---

add_property_override

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

attribute_name^Required

• Type: str

The name of the attribute.
