Interface TransferVariant<O>

Type Parameters:
O - The type of the immutable object instance, for example Item or Fluid.
All Superinterfaces:
net.minecraft.core.component.DataComponentGetter, net.minecraft.core.component.DataComponentHolder, net.minecraft.core.TypedInstance<O>
All Known Subinterfaces:
FluidVariant, ItemVariant
public interface TransferVariant<O> extends net.minecraft.core.component.DataComponentHolder, net.minecraft.core.TypedInstance<O>
An immutable association of an immutable object instance (for example Item or Fluid) and data components.

This is exposed for convenience for code that needs to be generic across multiple transfer variants, but note that a Storage is not necessarily bound to TransferVariant. Its generic parameter can be any immutable object.

Transfer variants must always be compared with equals, never by reference! hashCode is guaranteed to be correct and constant time independently of the size of the components.
