Method Details

change

public static <T> void change(@NotNull
 @NotNull Changer<T> changer,
 Object[] what,
 Object @Nullable [] delta,
 Changer.ChangeMode mode)

acceptsChange

public static boolean acceptsChange(@NotNull
 @NotNull Expression<?> expression,
 Changer.ChangeMode mode,
 Class<?>... types)

Tests whether an expression accepts changes of a certain type. If multiple types are given it test for whether any of the types is accepted.

Parameters:

expression - The expression to test

mode - The ChangeMode to use in the test

types - The types to test for

Returns:

Whether expression.change(event, type[], mode) can be used or not.

acceptsChangeTypes

public static boolean acceptsChangeTypes(Class<?>[] validTypes,
 Class<?> @NotNull ... types)

Tests whether any of the given types is accepted by the given array of valid types.

Parameters:

validTypes - The valid types. All array classes should be unwrapped to their component type before calling.

types - The types to test for

Returns:

Whether any of the types is accepted by the valid types.

getArithmeticChangeTypes

public static <T> Class<?>[] getArithmeticChangeTypes(Class<T> type,
 Changer.ChangeMode mode,
 Predicate<OperationInfo<T,?,?>> filter)

Gets the types that can be added/removed via arithmetic for the given type. This is used to determine accepted change types for add/remove when no changer is present.

Type Parameters:

T - The type to get arithmetic change types for.

Parameters:

type - The type to get arithmetic change types for.

mode - Whether to get addition or subtraction types. Only Changer.ChangeMode.ADD and Changer.ChangeMode.REMOVE are supported.

filter - A filter to apply to the available operations. Used for custom constraints on the operations, like ensuring the return type matches the left type.

Returns:

The types that can be added/removed via arithmetic for the given type and mode, after applying the filter.
