Field Details

wrappers

private static final Map<AbstractContainerMenu, CarriedSlotWrapper> wrappers

See VanillaContainerWrapper.wrappers which is similar.

We use weak keys and values to avoid keeping a strong reference to the AbstractContainerMenu until the next time the map is cleaned. As long as a wrapper is used, there is a strong reference to the AbstractContainerMenu class, which ensures that the entries remain in the map at least as long as the wrappers are in use.

Method Details

of

public static ResourceHandler<ItemResource> of(AbstractContainerMenu menu)

Return a wrapper around the carried slot of a menu, i.e. the stack that can be manipulated with AbstractContainerMenu.getCarried() and AbstractContainerMenu.setCarried(ItemStack).

getStack

protected ItemStack getStack()

Description copied from class: ItemStackResourceHandler

Return the stack of this handler. It will be modified directly sometimes to avoid needless copies. However, any mutation of the stack will directly be followed by a call to ItemStackResourceHandler.setStack(ItemStack). This means that either returning the backing stack directly or a copy is safe. If returning a copy, consider overriding ItemStackResourceHandler.getAmountAsLong(int) and ItemStackResourceHandler.getResource(int) to avoid unnecessary copies.

Specified by:

getStack in class ItemStackResourceHandler

Returns:

The current stack.

setStack

protected void setStack(ItemStack stack)

Description copied from class: ItemStackResourceHandler

Set the stack of this handler.

Specified by:

toString

public String toString()
