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

Interface StorageView<T>

Type Parameters:

T - The type of the stored resource. 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.

All Known Subinterfaces:

SingleSlotStorage<T>

All Known Implementing Classes:

BlankVariantView, FullItemFluidStorage, SingleFluidStorage, SingleStackStorage, SingleVariantItemStorage, SingleVariantStorage

@Experimental
public interface StorageView<T>

A view of a single stored resource in a Storage, for use with Storage.iterator(net.fabricmc.fabric.api.transfer.v1.transaction.TransactionContext) or Storage.exactView(net.fabricmc.fabric.api.transfer.v1.transaction.TransactionContext, T).

A view is always tied to a specific transaction, and should not be accessed outside of it.

Method Summary

Modifier and Type	Method	Description
long	extract(T resource, long maxAmount, TransactionContext transaction)	Try to extract a resource from this view.
long	getAmount()
long	getCapacity()
T	getResource()
boolean	isResourceBlank()	Return true if the getResource() contained in this storage view is blank, or false otherwise.

Method Details

extract

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

Try to extract a resource from this view.

Returns:

The amount that was extracted.

isResourceBlank

boolean isResourceBlank()

Return true if the 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().

getResource

T getResource()

Returns:

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

getAmount

long getAmount()

Returns:

The amount of getResource() stored in this view.

getCapacity

long getCapacity()

Returns:

The total amount of 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.
