Interface IngredientConverter<T>

public interface IngredientConverter<T>
Implement this interface to provide AE2s JEI integration with a new ingredient type converter for use in:
  • Recipe transfers
  • Pressing R/U on custom stacks in AE2 user interfaces
  • Dragging ghost items of custom types from JEI to AE2 interfaces

To register your converter, implement this interface and place the fully qualified class-name in a standard ServiceLoader file (/META-INF/services/appeng.api.integrations.jei.IngredientTypeConverter).

  • Method Details

    • getIngredientType

      mezz.jei.api.ingredients.IIngredientType<T> getIngredientType()
      The JEI ingredient type handled by this converter.

    • getIngredientFromStack

      @Nullable T getIngredientFromStack(GenericStack stack)
      Converts a generic stack into one of the ingredient handled by this converter.

      The converter needs to ensure the minimum amount of the returned ingredient is 1 if the resulting ingredient represents amounts of 0 as "empty", since this would not preserve the ingredient type correctly.

      Example: Math.max(1, Ints.saturatedCast(stack.amount())) (for Item and Fluid stacks).

      Returns:
      Null if the converter can't handle the stack.

    • getStackFromIngredient

      @Nullable @Nullable GenericStack getStackFromIngredient(T ingredient)
      Converts an ingredient handled by this converter into a generic stack.
      Returns:
      Null if the ingredient represents an "empty" ingredient (i.e. ItemStack.EMPTY.
