Identifies a custom recipe category shown in JEI when querying a specific ingredient.

A JEI category is identified by four major components: an id, a name, an icon, and a series of catalysts.

The ID is a unique name that is used by JEI to identify the category, in the form of a MCResourceLocation. With JeiTweaker, you have control only on the path portion of the location, whereas the ID is fixed to the one that represents the JeiTweaker mod.

The name is a MCTextComponent which identifies the category. It can be considered the human-friendly version of the category ID. More than one category can have the same name, although this is discouraged as a matter of clarity towards the player.

The icon is a JeiDrawable that is used as a graphic counterpart to the name, following the same rules. The icon is rendered on the top section of the JEI user interface. An example icon could be the crafting table for the minecraft:crafting category, or the furnace for the minecraft:furnace category.

Last but not least, the catalysts are a series of JeiIngredients that indicate where the recipe can be crafted. They appear on the left side of the JEI user interface, in a recessed rectangle. An example set of catalysts for the minecraft:crafting category could be all crafting tables, modded or otherwise. The set of catalysts might or might not contain the icon.

Moreover, each JeiTweaker category additionally specifies a background, which is used to provide a default background for recipes.For mod developers looking to create additional categories: each category is automatically discovered and registered by JeiTweaker as long as it extends JeiCategory and is annotated with both com.blamejared.crafttweaker.api.annotations.ZenRegister and org.openzen.zencode.java.ZenCodeType.Name. To be correctly registered, the class must not be abstract (preferably, it should be final) and it must have a constructor with the following signature: public ClassName(ResourceLocation, MCTextComponent, JeiDrawable, RawJeiIngredient...). Any other class is not going to be registered. Due to these requirements, mod developers are strongly encouraged not to implement this interface directly, but rather extend SimpleJeiCategory instead.

This class was added by a mod with mod-id jeitweaker. 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.
