Method Details

acceptChange

public @Nullable Class<?>[] acceptChange(Changer.ChangeMode mode)

Description copied from interface: Expression

Tests whether this expression supports the given mode, and if yes what type it expects the delta to be.

Use Changer.ChangerUtils.acceptsChange(Expression, ChangeMode, Class...) to test whether an expression supports changing, don't directly use this method!

Please note that if a changer is registered for this expression's returnType this method does not have to be overridden. If you override it though make sure to return super.acceptChange(mode), and to handle the appropriate ChangeMode(s) in Expression.change(Event, Object[], ChangeMode) with super.change(...).

Unlike Changer.acceptChange(ChangeMode) this method may print errors.

Specified by:

acceptChange in interface Expression<org.bukkit.inventory.ItemStack>

Overrides:

acceptChange in class EventValueExpression<org.bukkit.inventory.ItemStack>

Returns:

An array of types that Expression.change(Event, Object[], ChangeMode) accepts as its delta parameter (which can be arrays to denote that multiple of that type are accepted), or null if the given mode is not supported. For Changer.ChangeMode.DELETE and Changer.ChangeMode.RESET this can return any non-null array to mark them as supported.

change

public void change(org.bukkit.event.Event e,
 @Nullable Object[] delta,
 Changer.ChangeMode mode)

Description copied from interface: Expression

Changes the expression's value by the given amount. This will only be called on supported modes and with the desired delta type as returned by Expression.acceptChange(ChangeMode)

Specified by:

change in interface Expression<org.bukkit.inventory.ItemStack>

Overrides:

change in class EventValueExpression<org.bukkit.inventory.ItemStack>

delta - An array with one or more instances of one or more of the the classes returned by Expression.acceptChange(ChangeMode) for the given change mode (null for Changer.ChangeMode.DELETE and Changer.ChangeMode.RESET). This can be a Object[], thus casting is not allowed.
