Mixins are applied in order. The list of constructs is captured at the start of the call, so constructs added by a mixin will not be visited. Use multiple `with()` calls if subsequent mixins should apply to added constructs. #### `mixins`^Required * *Type:* \*constructs.IMixin The mixins to apply. *** ### `add_override` ```python theme={null} def add_override( path: str, value: typing.Any ) -> None ``` #### `path`^Required * *Type:* str *** #### `value`^Required * *Type:* typing.Any *** ### `override_logical_id` ```python theme={null} 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. *** ### `reset_override_logical_id` ```python theme={null} def reset_override_logical_id() -> None ``` Resets a previously passed logical Id to use the auto-generated logical id again. ### `to_hcl_terraform` ```python theme={null} def to_hcl_terraform() -> typing.Any ``` Adds this resource to the terraform JSON output. ### `to_metadata` ```python theme={null} def to_metadata() -> typing.Any ``` ### `to_terraform` ```python theme={null} def to_terraform() -> typing.Any ``` Adds this resource to the terraform JSON output. ### `get_any_map_attribute` ```python theme={null} def get_any_map_attribute( terraform_attribute: str ) -> typing.Mapping[typing.Any] ``` #### `terraform_attribute`^Required * *Type:* str *** ### `get_boolean_attribute` ```python theme={null} def get_boolean_attribute( terraform_attribute: str ) -> IResolvable ``` #### `terraform_attribute`^Required * *Type:* str *** ### `get_boolean_map_attribute` ```python theme={null} def get_boolean_map_attribute( terraform_attribute: str ) -> typing.Mapping[bool] ``` #### `terraform_attribute`^Required * *Type:* str *** ### `get_list_attribute` ```python theme={null} def get_list_attribute( terraform_attribute: str ) -> typing.List[str] ``` #### `terraform_attribute`^Required * *Type:* str *** ### `get_number_attribute` ```python theme={null} def get_number_attribute( terraform_attribute: str ) -> typing.Union[int, float] ``` #### `terraform_attribute`^Required * *Type:* str *** ### `get_number_list_attribute` ```python theme={null} def get_number_list_attribute( terraform_attribute: str ) -> typing.List[typing.Union[int, float]] ``` #### `terraform_attribute`^Required * *Type:* str *** ### `get_number_map_attribute` ```python theme={null} def get_number_map_attribute( terraform_attribute: str ) -> typing.Mapping[typing.Union[int, float]] ``` #### `terraform_attribute`^Required * *Type:* str *** ### `get_string_attribute` ```python theme={null} def get_string_attribute( terraform_attribute: str ) -> str ``` #### `terraform_attribute`^Required * *Type:* str *** ### `get_string_map_attribute` ```python theme={null} def get_string_map_attribute( terraform_attribute: str ) -> typing.Mapping[str] ``` #### `terraform_attribute`^Required * *Type:* str *** ### `interpolation_for_attribute` ```python theme={null} def interpolation_for_attribute( terraform_attribute: str ) -> IResolvable ``` #### `terraform_attribute`^Required * *Type:* str *** ## Static Functions | **Name** | **Description** | | ------------------------------------------------------------------------------------------------------- | ----------------------------- | | is\_construct | Checks if `x` is a construct. | | is\_terraform\_element | *No description.* | | is\_terraform\_data\_source | *No description.* | *** ### `is_construct` ```python theme={null} import cdktn cdktn.TerraformDataSource.is_construct( x: typing.Any ) ``` Checks if `x` is a construct. Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked. Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead. #### `x`^Required * *Type:* typing.Any Any object. *** ### `is_terraform_element` ```python theme={null} import cdktn cdktn.TerraformDataSource.is_terraform_element( x: typing.Any ) ``` #### `x`^Required * *Type:* typing.Any *** ### `is_terraform_data_source` ```python theme={null} import cdktn cdktn.TerraformDataSource.is_terraform_data_source( x: typing.Any ) ``` #### `x`^Required * *Type:* typing.Any *** ## Properties | **Name** | **Type** | **Description** | | ------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------- | ----------------- | | node | constructs.Node | The tree node. | | cdktf\_stack | TerraformStack | *No description.* | | fqn | str | *No description.* | | friendly\_unique\_id | str | *No description.* | | terraform\_meta\_arguments | typing.Mapping\[typing.Any] | *No description.* | | terraform\_resource\_type | str | *No description.* | | terraform\_generator\_metadata | TerraformProviderGeneratorMetadata | *No description.* | | count | typing.Union\[int, float] \| TerraformCount | *No description.* | | depends\_on | typing.List\[str] | *No description.* | | for\_each | ITerraformIterator | *No description.* | | lifecycle | TerraformResourceLifecycle | *No description.* | | provider | TerraformProvider | *No description.* | *** ### `node`^Required ```python theme={null} node: Node ``` * *Type:* constructs.Node The tree node. *** ### `cdktf_stack`^Required ```python theme={null} cdktf_stack: TerraformStack ``` * *Type:* TerraformStack *** ### `fqn`^Required ```python theme={null} fqn: str ``` * *Type:* str *** ### `friendly_unique_id`^Required ```python theme={null} friendly_unique_id: str ``` * *Type:* str *** ### `terraform_meta_arguments`^Required ```python theme={null} terraform_meta_arguments: typing.Mapping[typing.Any] ``` * *Type:* typing.Mapping\[typing.Any] *** ### `terraform_resource_type`^Required ```python theme={null} terraform_resource_type: str ``` * *Type:* str *** ### `terraform_generator_metadata`^Optional ```python theme={null} terraform_generator_metadata: TerraformProviderGeneratorMetadata ``` * *Type:* TerraformProviderGeneratorMetadata *** ### `count`^Optional ```python theme={null} count: typing.Union[int, float] | TerraformCount ``` * *Type:* typing.Union\[int, float] | TerraformCount *** ### `depends_on`^Optional ```python theme={null} depends_on: typing.List[str] ``` * *Type:* typing.List\[str] *** ### `for_each`^Optional ```python theme={null} for_each: ITerraformIterator ``` * *Type:* ITerraformIterator *** ### `lifecycle`^Optional ```python theme={null} lifecycle: TerraformResourceLifecycle ``` * *Type:* TerraformResourceLifecycle *** ### `provider`^Optional ```python theme={null} provider: TerraformProvider ``` * *Type:* TerraformProvider ***
