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:* params Constructs.IMixin\[] The mixins to apply. *** ### `AddOverride` ```csharp theme={null} private void AddOverride(string Path, object Value) ``` #### `Path`^Required * *Type:* string *** #### `Value`^Required * *Type:* object *** ### `OverrideLogicalId` ```csharp theme={null} private void OverrideLogicalId(string NewLogicalId) ``` 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` ```csharp theme={null} private void ResetOverrideLogicalId() ``` Resets a previously passed logical Id to use the auto-generated logical id again. ### `ToHclTerraform` ```csharp theme={null} private object ToHclTerraform() ``` Adds this resource to the terraform JSON output. ### `ToMetadata` ```csharp theme={null} private object ToMetadata() ``` ### `ToTerraform` ```csharp theme={null} private object ToTerraform() ``` Adds this resource to the terraform JSON output. ### `GetAnyMapAttribute` ```csharp theme={null} private System.Collections.Generic.IDictionary GetAnyMapAttribute(string TerraformAttribute) ``` #### `TerraformAttribute`^Required * *Type:* string *** ### `GetBooleanAttribute` ```csharp theme={null} private IResolvable GetBooleanAttribute(string TerraformAttribute) ``` #### `TerraformAttribute`^Required * *Type:* string *** ### `GetBooleanMapAttribute` ```csharp theme={null} private System.Collections.Generic.IDictionary GetBooleanMapAttribute(string TerraformAttribute) ``` #### `TerraformAttribute`^Required * *Type:* string *** ### `GetListAttribute` ```csharp theme={null} private string[] GetListAttribute(string TerraformAttribute) ``` #### `TerraformAttribute`^Required * *Type:* string *** ### `GetNumberAttribute` ```csharp theme={null} private double GetNumberAttribute(string TerraformAttribute) ``` #### `TerraformAttribute`^Required * *Type:* string *** ### `GetNumberListAttribute` ```csharp theme={null} private double[] GetNumberListAttribute(string TerraformAttribute) ``` #### `TerraformAttribute`^Required * *Type:* string *** ### `GetNumberMapAttribute` ```csharp theme={null} private System.Collections.Generic.IDictionary GetNumberMapAttribute(string TerraformAttribute) ``` #### `TerraformAttribute`^Required * *Type:* string *** ### `GetStringAttribute` ```csharp theme={null} private string GetStringAttribute(string TerraformAttribute) ``` #### `TerraformAttribute`^Required * *Type:* string *** ### `GetStringMapAttribute` ```csharp theme={null} private System.Collections.Generic.IDictionary GetStringMapAttribute(string TerraformAttribute) ``` #### `TerraformAttribute`^Required * *Type:* string *** ### `InterpolationForAttribute` ```csharp theme={null} private IResolvable InterpolationForAttribute(string TerraformAttribute) ``` #### `TerraformAttribute`^Required * *Type:* string *** ## Static Functions | **Name** | **Description** | | ------------------------------------------------------------------------------------------------- | ----------------------------- | | IsConstruct | Checks if `x` is a construct. | | IsTerraformElement | *No description.* | | IsTerraformDataSource | *No description.* | *** ### `IsConstruct` ```csharp theme={null} using Io.Cdktn; TerraformDataSource.IsConstruct(object X); ``` 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:* object Any object. *** ### `IsTerraformElement` ```csharp theme={null} using Io.Cdktn; TerraformDataSource.IsTerraformElement(object X); ``` #### `X`^Required * *Type:* object *** ### `IsTerraformDataSource` ```csharp theme={null} using Io.Cdktn; TerraformDataSource.IsTerraformDataSource(object X); ``` #### `X`^Required * *Type:* object *** ## Properties | **Name** | **Type** | **Description** | | -------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------- | ----------------- | | Node | Constructs.Node | The tree node. | | CdktfStack | TerraformStack | *No description.* | | Fqn | string | *No description.* | | FriendlyUniqueId | string | *No description.* | | TerraformMetaArguments | System.Collections.Generic.IDictionary\< string, object > | *No description.* | | TerraformResourceType | string | *No description.* | | TerraformGeneratorMetadata | TerraformProviderGeneratorMetadata | *No description.* | | Count | double\|TerraformCount | *No description.* | | DependsOn | string\[] | *No description.* | | ForEach | ITerraformIterator | *No description.* | | Lifecycle | TerraformResourceLifecycle | *No description.* | | Provider | TerraformProvider | *No description.* | *** ### `Node`^Required ```csharp theme={null} public Node Node { get; } ``` * *Type:* Constructs.Node The tree node. *** ### `CdktfStack`^Required ```csharp theme={null} public TerraformStack CdktfStack { get; } ``` * *Type:* TerraformStack *** ### `Fqn`^Required ```csharp theme={null} public string Fqn { get; } ``` * *Type:* string *** ### `FriendlyUniqueId`^Required ```csharp theme={null} public string FriendlyUniqueId { get; } ``` * *Type:* string *** ### `TerraformMetaArguments`^Required ```csharp theme={null} public System.Collections.Generic.IDictionary TerraformMetaArguments { get; } ``` * *Type:* System.Collections.Generic.IDictionary\< string, object > *** ### `TerraformResourceType`^Required ```csharp theme={null} public string TerraformResourceType { get; } ``` * *Type:* string *** ### `TerraformGeneratorMetadata`^Optional ```csharp theme={null} public TerraformProviderGeneratorMetadata TerraformGeneratorMetadata { get; } ``` * *Type:* TerraformProviderGeneratorMetadata *** ### `Count`^Optional ```csharp theme={null} public double|TerraformCount Count { get; } ``` * *Type:* double|TerraformCount *** ### `DependsOn`^Optional ```csharp theme={null} public string[] DependsOn { get; } ``` * *Type:* string\[] *** ### `ForEach`^Optional ```csharp theme={null} public ITerraformIterator ForEach { get; } ``` * *Type:* ITerraformIterator *** ### `Lifecycle`^Optional ```csharp theme={null} public TerraformResourceLifecycle Lifecycle { get; } ``` * *Type:* TerraformResourceLifecycle *** ### `Provider`^Optional ```csharp theme={null} public TerraformProvider Provider { get; } ``` * *Type:* TerraformProvider ***
