# ListData

## Importing the class

It might be required for you to import the package if you encounter any issues (like casting an Array), so better be safe than sorry and add the import at the very top of the file.
```zenscript
import crafttweaker.api.data.ListData;
```


## Implemented Interfaces
ListData implements the following interfaces. That means all methods defined in these interfaces are also available in ListData

- [ICollectionData](/vanilla/api/data/ICollectionData)

## Static Methods

:::group{name=create}

Return Type: [ListData](/vanilla/api/data/ListData)

```zenscript
// ListData.create() as ListData

ListData.create();
```

:::

## Constructors


```zenscript
new ListData() as ListData
new ListData();
```

```zenscript
new ListData(list as stdlib.List<IData>) as ListData
```
| Parameter | Type                                                            |
| --------- | --------------------------------------------------------------- |
| list      | stdlib.List&lt;[IData](/vanilla/api/data/IData)&gt; |

```

:::

:::group{name=asString}

Gets the String representation of this IData

Returns: String that represents this IData (value and type).  
Return Type: string

```zenscript
// ListData.asString() as string

["Hello", "World", "!"].asString();
```

:::

:::group{name=getData}

Return Type: @org.openzen.zencode.java.ZenCodeType.Nullable T

```zenscript
ListData.getData<T : IData>(index as int) as @org.openzen.zencode.java.ZenCodeType.Nullable T
```

| Parameter | Type                             |
| --------- | -------------------------------- |
| index     | int                              |
| T         | [IData](/vanilla/api/data/IData) |


:::

:::group{name=getId}

Gets the ID of the internal NBT tag.

 Used to determine what NBT type is stored (in a list for example)

Returns: ID of the NBT tag that this data represents.  
Return Type: byte

```zenscript
// ListData.getId() as byte

["Hello", "World", "!"].getId();
```

:::

:::group{name=getString}

Gets the String representation of the internal INBT tag
