cdktn.NewTerraformVariable(scope Construct, id *string, config TerraformVariableConfig) TerraformVariable
```
| **Name** | **Type** | **Description** |
| --------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------- | ----------------- |
| scope | github.com/aws/constructs-go/constructs/v10.Construct | *No description.* |
| id | \*string | *No description.* |
| config | TerraformVariableConfig | *No description.* |
***
### `scope`Required
* *Type:* github.com/aws/constructs-go/constructs/v10.Construct
***
### `id`Required
* *Type:* \*string
***
### `config`Required
* *Type:* TerraformVariableConfig
***
## Methods
| **Name** | **Description** |
| --------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------- |
| ToString | Returns a string representation of this construct. |
| With | Applies one or more mixins to this construct. |
| AddOverride | *No description.* |
| OverrideLogicalId | Overrides the auto-generated logical ID with a specific ID. |
| ResetOverrideLogicalId | Resets a previously passed logical Id to use the auto-generated logical id again. |
| ToHclTerraform | *No description.* |
| ToMetadata | *No description.* |
| ToTerraform | *No description.* |
| AddValidation | *No description.* |
| SynthesizeAttributes | *No description.* |
| SynthesizeHclAttributes | *No description.* |
***
### `ToString`
```go theme={null}
func ToString() *string
```
Returns a string representation of this construct.
### `With`
```go theme={null}
func With(mixins ...IMixin) IConstruct
```
Applies one or more mixins to this construct.
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{}
```
### `ToMetadata`
```go theme={null}
func ToMetadata() interface{}
```
### `ToTerraform`
```go theme={null}
func ToTerraform() interface{}
```
### `AddValidation`
```go theme={null}
func AddValidation(validation TerraformVariableValidationConfig)
```
#### `validation`Required
* *Type:* TerraformVariableValidationConfig
***
### `SynthesizeAttributes`
```go theme={null}
func SynthesizeAttributes() *map[string]interface{}
```
### `SynthesizeHclAttributes`
```go theme={null}
func SynthesizeHclAttributes() *map[string]interface{}
```
## Static Functions
| **Name** | **Description** |
| ----------------------------------------------------------------------------------------- | ----------------------------- |
| IsConstruct | Checks if `x` is a construct. |
| IsTerraformElement | *No description.* |
***
### `IsConstruct`
```go theme={null}
import "github.com/open-constructs/cdk-terrain-go/cdktn"
cdktn.TerraformVariable_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.TerraformVariable_IsTerraformElement(x interface{}) *bool
```
#### `x`Required
* *Type:* interface\{}
