Method Details

move

@NotNull
public static @NotNull TransferResult move(@NotNull
 @NotNull ResourceHandler source,
 @NotNull
 @NotNull ResourceHandler target,
 @NotNull
 @NotNull Predicate<ResourceVariant> filter,
 long maxAmount,
 @NotNull
 @NotNull TransactionContext transaction)

Moves up to maxAmount of variants matching filter from source to target inside transaction. Each variant moves in its own nested transaction, so a misbehaving handler can never lose or create resources.

simulateInsert

public static long simulateInsert(@NotNull
 @NotNull ResourceHandler handler,
 @NotNull
 @NotNull ResourceVariant variant,
 long maxAmount,
 @NotNull
 @NotNull TransactionContext transaction)

Returns:

how much handler would accept, without changing it
