Package net.fabricmc.fabric.api.transfer.v1.storage.base

Class BlankVariantView<T extends TransferVariant<?>>

java.lang.Object

net.fabricmc.fabric.api.transfer.v1.storage.base.BlankVariantView<T>

All Implemented Interfaces:

StorageView<T>

@Experimental
public class BlankVariantView<T extends TransferVariant<?>>
extends Object
implements StorageView<T>

A transfer variant storage view that contains a blank variant all the time (it's always empty), but may have a nonzero capacity. This can be used to give capacity hints even if the storage is empty.

Experimental feature, we reserve the right to remove or change it without further notice. The transfer API is a complex addition, and we want to be able to correct possible design mistakes.

Method Details

extract

public long extract(T resource,
 long maxAmount,
 TransactionContext transaction)

Description copied from interface: StorageView

Try to extract a resource from this view.

Specified by:

extract in interface StorageView<T extends TransferVariant<?>>

Returns:

The amount that was extracted.

isResourceBlank

public boolean isResourceBlank()

Description copied from interface: StorageView

Return true if the StorageView.getResource() contained in this storage view is blank, or false otherwise.

This function is mostly useful when dealing with storages of arbitrary types. For transfer variant storages, this should always be equivalent to getResource().isBlank().

Specified by:

isResourceBlank in interface StorageView<T extends TransferVariant<?>>

getResource

public T getResource()

Specified by:

getResource in interface StorageView<T extends TransferVariant<?>>

Returns:

The resource stored in this view. May not be blank if StorageView.isResourceBlank() is false.

getAmount

public long getAmount()

Specified by:

getAmount in interface StorageView<T extends TransferVariant<?>>

Returns:

The amount of StorageView.getResource() stored in this view.

getCapacity

public long getCapacity()

Specified by:

getCapacity in interface StorageView<T extends TransferVariant<?>>

Returns:

The total amount of StorageView.getResource() that could be stored in this view, or an estimate of the number of resources that could be stored if this view has a blank resource.
