All Implemented Interfaces:
ICapabilityProvider, IFluidHandler, IFluidHandlerItem
Direct Known Subclasses:
FluidHandlerItemStack.Consumable, FluidHandlerItemStack.SwapEmpty
public class FluidHandlerItemStack extends Object implements IFluidHandlerItem, ICapabilityProvider
FluidHandlerItemStack is a template capability provider for ItemStacks. Data is stored directly in the vanilla NBT, in the same way as the old ItemFluidContainer. This class allows an ItemStack to contain any partial level of fluid up to its capacity, unlike FluidHandlerItemStackSimple Additional examples are provided to enable consumable fluid containers (see FluidHandlerItemStack.Consumable), fluid containers with different empty and full items (see FluidHandlerItemStack.SwapEmpty,

    • FluidHandlerItemStack

      public FluidHandlerItemStack(@NotNull @NotNull ItemStack container, int capacity)
      Parameters:
      container - The container itemStack, data is stored on it directly as NBT.
      capacity - The maximum capacity of this fluid tank.

  • Method Details

    • getContainer

      @NotNull public @NotNull ItemStack getContainer()
      Description copied from interface: IFluidHandlerItem
      Get the container currently acted on by this fluid handler. The ItemStack may be different from its initial state, in the case of fluid containers that have different items for their filled and empty states. May be an empty item if the container was drained and is consumable.
      Specified by:
      getContainer in interface IFluidHandlerItem

    • getFluid

      @NotNull public @NotNull FluidStack getFluid()

    • setFluid

      protected void setFluid(FluidStack fluid)

    • getTanks

      public int getTanks()
      Description copied from interface: IFluidHandler
      Returns the number of fluid storage units ("tanks") available
      Specified by:
      getTanks in interface IFluidHandler
      Returns:
      The number of tanks available

    • getFluidInTank

      @NotNull public @NotNull FluidStack getFluidInTank(int tank)
      Description copied from interface: IFluidHandler
      Returns the FluidStack in a given tank.

      IMPORTANT: This FluidStack MUST NOT be modified. This method is not for altering internal contents. Any implementers who are able to detect modification via this method should throw an exception. It is ENTIRELY reasonable and likely that the stack returned here will be a copy.

      SERIOUSLY: DO NOT MODIFY THE RETURNED FLUIDSTACK

      Specified by:
      getFluidInTank in interface IFluidHandler
      Parameters:
      tank - Tank to query.
      Returns:
      FluidStack in a given tank. FluidStack.EMPTY if the tank is empty.

    • getTankCapacity

      public int getTankCapacity(int tank)
      Description copied from interface: IFluidHandler
      Retrieves the maximum fluid amount for a given tank.
      Specified by:
      getTankCapacity in interface IFluidHandler
      Parameters:
      tank - Tank to query.
      Returns:
      The maximum fluid amount held by the tank.

    • isFluidValid

      public boolean isFluidValid(int tank, @NotNull @NotNull FluidStack stack)
      Description copied from interface: IFluidHandler
      This function is a way to determine which fluids can exist inside a given handler. General purpose tanks will basically always return TRUE for this.
      Specified by:
      isFluidValid in interface IFluidHandler
      Parameters:
      tank - Tank to query for validity
      stack - Stack to test with for validity
      Returns:
      TRUE if the tank can hold the FluidStack, not considering current state. (Basically, is a given fluid EVER allowed in this tank?) Return FALSE if the answer to that question is 'no.'

    • fill

      public int fill(FluidStack resource, IFluidHandler.FluidAction doFill)
      Description copied from interface: IFluidHandler
      Fills fluid into internal tanks, distribution is left entirely to the IFluidHandler.
      Specified by:
      fill in interface IFluidHandler
      Parameters:
      resource - FluidStack representing the Fluid and maximum amount of fluid to be filled.
      doFill - If SIMULATE, fill will only be simulated.
      Returns:
      Amount of resource that was (or would have been, if simulated) filled.

    • drain

      @NotNull public @NotNull FluidStack drain(FluidStack resource, IFluidHandler.FluidAction action)
      Description copied from interface: IFluidHandler
      Drains fluid out of internal tanks, distribution is left entirely to the IFluidHandler.
      Specified by:
      drain in interface IFluidHandler
      Parameters:
      resource - FluidStack representing the Fluid and maximum amount of fluid to be drained.
      action - If SIMULATE, drain will only be simulated.
      Returns:
      FluidStack representing the Fluid and amount that was (or would have been, if simulated) drained.

    • drain

      @NotNull public @NotNull FluidStack drain(int maxDrain, IFluidHandler.FluidAction action)
      Description copied from interface: IFluidHandler
      Drains fluid out of internal tanks, distribution is left entirely to the IFluidHandler.

      This method is not Fluid-sensitive.

      Specified by:
      drain in interface IFluidHandler
      Parameters:
      maxDrain - Maximum amount of fluid to drain.
      action - If SIMULATE, drain will only be simulated.
      Returns:
      FluidStack representing the Fluid and amount that was (or would have been, if simulated) drained.

    • canFillFluidType

      public boolean canFillFluidType(FluidStack fluid)

    • canDrainFluidType

      public boolean canDrainFluidType(FluidStack fluid)

    • setContainerToEmpty

      protected void setContainerToEmpty()
      Override this method for special handling. Can be used to swap out or destroy the container.

    • getCapability

      @NotNull public <T> @NotNull LazyOptional<T> getCapability(@NotNull @NotNull Capability<T> capability, @Nullable @Nullable Direction facing)
      Description copied from interface: ICapabilityProvider
      Retrieves the Optional handler for the capability requested on the specific side. The return value CAN be the same for multiple faces. Modders are encouraged to cache this value, using the listener capabilities of the Optional to be notified if the requested capability get lost.
      Specified by:
      getCapability in interface ICapabilityProvider
      Parameters:
      capability - The capability to check
      facing - The Side to check from, CAN BE NULL. Null is defined to represent 'internal' or 'self'
      Returns:
      The requested an optional holding the requested capability.
