# BracketValidators

This class was added by a mod with mod-id `mekanism`. So you need to have this mod installed if you
want to use this feature.

## 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 mods.mekanism.api.BracketValidators;
```

This class allows you to check whether a certain Object exists or not before using the [BracketHandlers](/mods/Mekanism/api/BracketHandlers) class. All methods return a boolean that represents whether the passed in registry name or location has an Object associated to it.

Just like with the [BracketHandlers](/mods/Mekanism/api/BracketHandlers), most of these are accessible through the `/ct dump` subcommands added by Mekanism or through their in-game names. Make sure to remove the prefix from the bracket you get, because that is handled by the static, specific method you use in this class. 
This means, no `gas` or other chemical prefix, just modid and name.
