Method Detail

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

@Nonnull
public 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,
                            @Nonnull
                            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 action)

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.

action - If SIMULATE, fill will only be simulated.

Returns:

Amount of resource that was (or would have been, if simulated) filled.

drain

@Nonnull
public 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

@Nonnull
public 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.
