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:* software.constructs.IMixin...

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:* java.lang.Object Any object. *** ### `isTerraformElement` ```java theme={null} import io.cdktn.cdktn.TerraformDataSource; TerraformDataSource.isTerraformElement(java.lang.Object x) ``` #### `x`^Required * *Type:* java.lang.Object *** ### `isTerraformDataSource` ```java theme={null} import io.cdktn.cdktn.TerraformDataSource; TerraformDataSource.isTerraformDataSource(java.lang.Object x) ``` #### `x`^Required * *Type:* java.lang.Object *** ## Properties | **Name** | **Type** | **Description** | | -------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------- | ----------------- | | node | software.constructs.Node | The tree node. | | cdktfStack | TerraformStack | *No description.* | | fqn | java.lang.String | *No description.* | | friendlyUniqueId | java.lang.String | *No description.* | | terraformMetaArguments | java.util.Map\< java.lang.String, java.lang.Object > | *No description.* | | terraformResourceType | java.lang.String | *No description.* | | terraformGeneratorMetadata | TerraformProviderGeneratorMetadata | *No description.* | | count | java.lang.Number\|TerraformCount | *No description.* | | dependsOn | java.util.List\< java.lang.String > | *No description.* | | forEach | ITerraformIterator | *No description.* | | lifecycle | TerraformResourceLifecycle | *No description.* | | provider | TerraformProvider | *No description.* | *** ### `node`^Required ```java theme={null} public Node getNode(); ``` * *Type:* software.constructs.Node The tree node. *** ### `cdktfStack`^Required ```java theme={null} public TerraformStack getCdktfStack(); ``` * *Type:* TerraformStack *** ### `fqn`^Required ```java theme={null} public java.lang.String getFqn(); ``` * *Type:* java.lang.String *** ### `friendlyUniqueId`^Required ```java theme={null} public java.lang.String getFriendlyUniqueId(); ``` * *Type:* java.lang.String *** ### `terraformMetaArguments`^Required ```java theme={null} public java.util.Map getTerraformMetaArguments(); ``` * *Type:* java.util.Map\< java.lang.String, java.lang.Object > *** ### `terraformResourceType`^Required ```java theme={null} public java.lang.String getTerraformResourceType(); ``` * *Type:* java.lang.String *** ### `terraformGeneratorMetadata`^Optional ```java theme={null} public TerraformProviderGeneratorMetadata getTerraformGeneratorMetadata(); ``` * *Type:* TerraformProviderGeneratorMetadata *** ### `count`^Optional ```java theme={null} public java.lang.Number|TerraformCount getCount(); ``` * *Type:* java.lang.Number|TerraformCount *** ### `dependsOn`^Optional ```java theme={null} public java.util.List getDependsOn(); ``` * *Type:* java.util.List\< java.lang.String > *** ### `forEach`^Optional ```java theme={null} public ITerraformIterator getForEach(); ``` * *Type:* ITerraformIterator *** ### `lifecycle`^Optional ```java theme={null} public TerraformResourceLifecycle getLifecycle(); ``` * *Type:* TerraformResourceLifecycle *** ### `provider`^Optional ```java theme={null} public TerraformProvider getProvider(); ``` * *Type:* TerraformProvider ***
