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. *** ### `addOverride` ```typescript theme={null} public addOverride(path: string, value: any): void ``` #### `path`^Required * *Type:* string *** #### `value`^Required * *Type:* any *** ### `overrideLogicalId` ```typescript theme={null} public overrideLogicalId(newLogicalId: string): void ``` Overrides the auto-generated logical ID with a specific ID. #### `newLogicalId`^Required * *Type:* string The new logical ID to use for this stack element. *** ### `resetOverrideLogicalId` ```typescript theme={null} public resetOverrideLogicalId(): void ``` Resets a previously passed logical Id to use the auto-generated logical id again. ### `toHclTerraform` ```typescript theme={null} public toHclTerraform(): any ``` Adds this resource to the terraform JSON output. ### `toMetadata` ```typescript theme={null} public toMetadata(): any ``` ### `toTerraform` ```typescript theme={null} public toTerraform(): any ``` Adds this resource to the terraform JSON output. ### `getAnyMapAttribute` ```typescript theme={null} public getAnyMapAttribute(terraformAttribute: string): {[ key: string ]: any} ``` #### `terraformAttribute`^Required * *Type:* string *** ### `getBooleanAttribute` ```typescript theme={null} public getBooleanAttribute(terraformAttribute: string): IResolvable ``` #### `terraformAttribute`^Required * *Type:* string *** ### `getBooleanMapAttribute` ```typescript theme={null} public getBooleanMapAttribute(terraformAttribute: string): {[ key: string ]: boolean} ``` #### `terraformAttribute`^Required * *Type:* string *** ### `getListAttribute` ```typescript theme={null} public getListAttribute(terraformAttribute: string): string[] ``` #### `terraformAttribute`^Required * *Type:* string *** ### `getNumberAttribute` ```typescript theme={null} public getNumberAttribute(terraformAttribute: string): number ``` #### `terraformAttribute`^Required * *Type:* string *** ### `getNumberListAttribute` ```typescript theme={null} public getNumberListAttribute(terraformAttribute: string): number[] ``` #### `terraformAttribute`^Required * *Type:* string *** ### `getNumberMapAttribute` ```typescript theme={null} public getNumberMapAttribute(terraformAttribute: string): {[ key: string ]: number} ``` #### `terraformAttribute`^Required * *Type:* string *** ### `getStringAttribute` ```typescript theme={null} public getStringAttribute(terraformAttribute: string): string ``` #### `terraformAttribute`^Required * *Type:* string *** ### `getStringMapAttribute` ```typescript theme={null} public getStringMapAttribute(terraformAttribute: string): {[ key: string ]: string} ``` #### `terraformAttribute`^Required * *Type:* string *** ### `interpolationForAttribute` ```typescript theme={null} public interpolationForAttribute(terraformAttribute: string): IResolvable ``` #### `terraformAttribute`^Required * *Type:* string *** ## Static Functions | **Name** | **Description** | | ------------------------------------------------------------------------------------------------- | ----------------------------- | | isConstruct | Checks if `x` is a construct. | | isTerraformElement | *No description.* | | isTerraformDataSource | *No description.* | *** ### `isConstruct` ```typescript theme={null} import { TerraformDataSource } from 'cdktn' TerraformDataSource.isConstruct(x: 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:* any Any object. *** ### `isTerraformElement` ```typescript theme={null} import { TerraformDataSource } from 'cdktn' TerraformDataSource.isTerraformElement(x: any) ``` #### `x`^Required * *Type:* any *** ### `isTerraformDataSource` ```typescript theme={null} import { TerraformDataSource } from 'cdktn' TerraformDataSource.isTerraformDataSource(x: any) ``` #### `x`^Required * *Type:* any *** ## Properties | **Name** | **Type** | **Description** | | -------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------- | ----------------- | | node | constructs.Node | The tree node. | | cdktfStack | TerraformStack | *No description.* | | fqn | string | *No description.* | | friendlyUniqueId | string | *No description.* | | terraformMetaArguments | \{\[ key: string ]: any} | *No description.* | | terraformResourceType | string | *No description.* | | terraformGeneratorMetadata | TerraformProviderGeneratorMetadata | *No description.* | | count | number \| TerraformCount | *No description.* | | dependsOn | string\[] | *No description.* | | forEach | ITerraformIterator | *No description.* | | lifecycle | TerraformResourceLifecycle | *No description.* | | provider | TerraformProvider | *No description.* | *** ### `node`^Required ```typescript theme={null} public readonly node: Node; ``` * *Type:* constructs.Node The tree node. *** ### `cdktfStack`^Required ```typescript theme={null} public readonly cdktfStack: TerraformStack; ``` * *Type:* TerraformStack *** ### `fqn`^Required ```typescript theme={null} public readonly fqn: string; ``` * *Type:* string *** ### `friendlyUniqueId`^Required ```typescript theme={null} public readonly friendlyUniqueId: string; ``` * *Type:* string *** ### `terraformMetaArguments`^Required ```typescript theme={null} public readonly terraformMetaArguments: {[ key: string ]: any}; ``` * *Type:* \{\[ key: string ]: any} *** ### `terraformResourceType`^Required ```typescript theme={null} public readonly terraformResourceType: string; ``` * *Type:* string *** ### `terraformGeneratorMetadata`^Optional ```typescript theme={null} public readonly terraformGeneratorMetadata: TerraformProviderGeneratorMetadata; ``` * *Type:* TerraformProviderGeneratorMetadata *** ### `count`^Optional ```typescript theme={null} public readonly count: number | TerraformCount; ``` * *Type:* number | TerraformCount *** ### `dependsOn`^Optional ```typescript theme={null} public readonly dependsOn: string[]; ``` * *Type:* string\[] *** ### `forEach`^Optional ```typescript theme={null} public readonly forEach: ITerraformIterator; ``` * *Type:* ITerraformIterator *** ### `lifecycle`^Optional ```typescript theme={null} public readonly lifecycle: TerraformResourceLifecycle; ``` * *Type:* TerraformResourceLifecycle *** ### `provider`^Optional ```typescript theme={null} public readonly provider: TerraformProvider; ``` * *Type:* TerraformProvider ***
