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. *** ### `addDependency` ```typescript theme={null} public addDependency(dependency: TerraformStack): void ``` #### `dependency`^Required * *Type:* TerraformStack *** ### `addOverride` ```typescript theme={null} public addOverride(path: string, value: any): void ``` #### `path`^Required * *Type:* string *** #### `value`^Required * *Type:* any *** ### `allProviders` ```typescript theme={null} public allProviders(): TerraformProvider[] ``` ### `dependsOn` ```typescript theme={null} public dependsOn(stack: TerraformStack): boolean ``` #### `stack`^Required * *Type:* TerraformStack *** ### `ensureBackendExists` ```typescript theme={null} public ensureBackendExists(): TerraformBackend ``` ### `getLogicalId` ```typescript theme={null} public getLogicalId(tfElement: Node | TerraformElement): string ``` #### `tfElement`^Required * *Type:* constructs.Node | TerraformElement *** ### `hasResourceMove` ```typescript theme={null} public hasResourceMove(): boolean ``` ### `prepareStack` ```typescript theme={null} public prepareStack(): void ``` ### `registerIncomingCrossStackReference` ```typescript theme={null} public registerIncomingCrossStackReference(fromStack: TerraformStack): TerraformRemoteState ``` #### `fromStack`^Required * *Type:* TerraformStack *** ### `registerOutgoingCrossStackReference` ```typescript theme={null} public registerOutgoingCrossStackReference(identifier: string): TerraformOutput ``` #### `identifier`^Required * *Type:* string *** ### `runAllValidations` ```typescript theme={null} public runAllValidations(): void ``` Run all validations on the stack. ### `toHclTerraform` ```typescript theme={null} public toHclTerraform(): {[ key: string ]: any} ``` ### `toTerraform` ```typescript theme={null} public toTerraform(): any ``` ## Static Functions | **Name** | **Description** | | ------------------------------------------------------------------------ | ----------------------------- | | isConstruct | Checks if `x` is a construct. | | isStack | *No description.* | | of | *No description.* | *** ### `isConstruct` ```typescript theme={null} import { TerraformStack } from 'cdktn' TerraformStack.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. *** ### `isStack` ```typescript theme={null} import { TerraformStack } from 'cdktn' TerraformStack.isStack(x: any) ``` #### `x`^Required * *Type:* any *** ### `of` ```typescript theme={null} import { TerraformStack } from 'cdktn' TerraformStack.of(construct: IConstruct) ``` #### `construct`^Required * *Type:* constructs.IConstruct *** ## Properties | **Name** | **Type** | **Description** | | ----------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------- | ----------------- | | node | constructs.Node | The tree node. | | dependencies | TerraformStack\[] | *No description.* | | moveTargets | TerraformResourceTargets | *No description.* | | synthesizer | IStackSynthesizer | *No description.* | *** ### `node`^Required ```typescript theme={null} public readonly node: Node; ``` * *Type:* constructs.Node The tree node. *** ### `dependencies`^Required ```typescript theme={null} public readonly dependencies: TerraformStack[]; ``` * *Type:* TerraformStack\[] *** ### `moveTargets`^Required ```typescript theme={null} public readonly moveTargets: TerraformResourceTargets; ``` * *Type:* TerraformResourceTargets *** ### `synthesizer`^Required ```typescript theme={null} public readonly synthesizer: IStackSynthesizer; ``` * *Type:* IStackSynthesizer ***
