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:* ...github.com/aws/constructs-go/constructs/v10.IMixin The mixins to apply. *** ### `AddOverride` ```go theme={null} func AddOverride(path *string, value interface{}) ``` #### `path`^Required * *Type:* \*string *** #### `value`^Required * *Type:* interface\{} *** ### `OverrideLogicalId` ```go theme={null} func OverrideLogicalId(newLogicalId *string) ``` 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` ```go theme={null} func ResetOverrideLogicalId() ``` Resets a previously passed logical Id to use the auto-generated logical id again. ### `ToHclTerraform` ```go theme={null} func ToHclTerraform() interface{} ``` Adds this resource to the terraform JSON output. ### `ToMetadata` ```go theme={null} func ToMetadata() interface{} ``` ### `ToTerraform` ```go theme={null} func ToTerraform() interface{} ``` Adds this resource to the terraform JSON output. ### `GetAnyMapAttribute` ```go theme={null} func GetAnyMapAttribute(terraformAttribute *string) *map[string]interface{} ``` #### `terraformAttribute`^Required * *Type:* \*string *** ### `GetBooleanAttribute` ```go theme={null} func GetBooleanAttribute(terraformAttribute *string) IResolvable ``` #### `terraformAttribute`^Required * *Type:* \*string *** ### `GetBooleanMapAttribute` ```go theme={null} func GetBooleanMapAttribute(terraformAttribute *string) *map[string]*bool ``` #### `terraformAttribute`^Required * *Type:* \*string *** ### `GetListAttribute` ```go theme={null} func GetListAttribute(terraformAttribute *string) *[]*string ``` #### `terraformAttribute`^Required * *Type:* \*string *** ### `GetNumberAttribute` ```go theme={null} func GetNumberAttribute(terraformAttribute *string) *f64 ``` #### `terraformAttribute`^Required * *Type:* \*string *** ### `GetNumberListAttribute` ```go theme={null} func GetNumberListAttribute(terraformAttribute *string) *[]*f64 ``` #### `terraformAttribute`^Required * *Type:* \*string *** ### `GetNumberMapAttribute` ```go theme={null} func GetNumberMapAttribute(terraformAttribute *string) *map[string]*f64 ``` #### `terraformAttribute`^Required * *Type:* \*string *** ### `GetStringAttribute` ```go theme={null} func GetStringAttribute(terraformAttribute *string) *string ``` #### `terraformAttribute`^Required * *Type:* \*string *** ### `GetStringMapAttribute` ```go theme={null} func GetStringMapAttribute(terraformAttribute *string) *map[string]*string ``` #### `terraformAttribute`^Required * *Type:* \*string *** ### `InterpolationForAttribute` ```go theme={null} func 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` ```go theme={null} import "github.com/open-constructs/cdk-terrain-go/cdktn" cdktn.TerraformDataSource_IsConstruct(x interface{}) *bool ``` 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:* interface\{} Any object. *** ### `IsTerraformElement` ```go theme={null} import "github.com/open-constructs/cdk-terrain-go/cdktn" cdktn.TerraformDataSource_IsTerraformElement(x interface{}) *bool ``` #### `x`^Required * *Type:* interface\{} *** ### `IsTerraformDataSource` ```go theme={null} import "github.com/open-constructs/cdk-terrain-go/cdktn" cdktn.TerraformDataSource_IsTerraformDataSource(x interface{}) *bool ``` #### `x`^Required * *Type:* interface\{} *** ## Properties | **Name** | **Type** | **Description** | | -------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------- | ----------------- | | Node | github.com/aws/constructs-go/constructs/v10.Node | The tree node. | | CdktfStack | TerraformStack | *No description.* | | Fqn | \*string | *No description.* | | FriendlyUniqueId | \*string | *No description.* | | TerraformMetaArguments | \*map\[string]interface\{} | *No description.* | | TerraformResourceType | \*string | *No description.* | | TerraformGeneratorMetadata | TerraformProviderGeneratorMetadata | *No description.* | | Count | interface\{} | *No description.* | | DependsOn | \*\[]\*string | *No description.* | | ForEach | ITerraformIterator | *No description.* | | Lifecycle | TerraformResourceLifecycle | *No description.* | | Provider | TerraformProvider | *No description.* | *** ### `Node`^Required ```go theme={null} func Node() Node ``` * *Type:* github.com/aws/constructs-go/constructs/v10.Node The tree node. *** ### `CdktfStack`^Required ```go theme={null} func CdktfStack() TerraformStack ``` * *Type:* TerraformStack *** ### `Fqn`^Required ```go theme={null} func Fqn() *string ``` * *Type:* \*string *** ### `FriendlyUniqueId`^Required ```go theme={null} func FriendlyUniqueId() *string ``` * *Type:* \*string *** ### `TerraformMetaArguments`^Required ```go theme={null} func TerraformMetaArguments() *map[string]interface{} ``` * *Type:* \*map\[string]interface\{} *** ### `TerraformResourceType`^Required ```go theme={null} func TerraformResourceType() *string ``` * *Type:* \*string *** ### `TerraformGeneratorMetadata`^Optional ```go theme={null} func TerraformGeneratorMetadata() TerraformProviderGeneratorMetadata ``` * *Type:* TerraformProviderGeneratorMetadata *** ### `Count`^Optional ```go theme={null} func Count() interface{} ``` * *Type:* interface\{} *** ### `DependsOn`^Optional ```go theme={null} func DependsOn() *[]*string ``` * *Type:* \*\[]\*string *** ### `ForEach`^Optional ```go theme={null} func ForEach() ITerraformIterator ``` * *Type:* ITerraformIterator *** ### `Lifecycle`^Optional ```go theme={null} func Lifecycle() TerraformResourceLifecycle ``` * *Type:* TerraformResourceLifecycle *** ### `Provider`^Optional ```go theme={null} func Provider() TerraformProvider ``` * *Type:* TerraformProvider ***
