Method Details

init

public boolean init(Expression<?>[] vars,
 int matchedPattern,
 Kleenean isDelayed,
 SkriptParser.ParseResult parser)

Description copied from interface: SyntaxElement

Called just after the constructor.

Parameters:

vars - all %expr%s included in the matching pattern in the order they appear in the pattern. If an optional value was left out it will still be included in this list holding the default value of the desired type which usually depends on the event.

matchedPattern - The index of the pattern which matched

isDelayed - Whether this expression is used after a delay or not (i.e. if the event has already passed when this expression will be called)

parser - Additional information about the match.

Returns:

Whether this expression was initialised successfully. An error should be printed prior to returning false to specify the cause.

See Also:

ParserInstance.isCurrentEvent(Class...)

get

protected Number[] get(org.bukkit.event.Event e,
 org.bukkit.entity.LivingEntity[] source)

Description copied from class: PropertyExpression

Converts the given source object(s) to the correct type.

Please note that the returned array must neither be null nor contain any null elements!

Specified by:

get in class PropertyExpression<org.bukkit.entity.LivingEntity,Number>

Returns:

An array of the converted objects, which may contain less elements than the source array, but must not be null.

See Also:

Converters.convert(Object[], Class, Converter)

toString

public String toString(@Nullable org.bukkit.event.Event e,
 boolean debug)

Parameters:

e - The event to get information to. This is always null if debug == false.

debug - If true this should print more information, if false this should print what is shown to the end user

Returns:

String representation of this object

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<Number>

Overrides:

acceptChange in class SimpleExpression<Number>

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<Number>

Overrides:

change in class SimpleExpression<Number>

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.

getReturnType

public Class<? extends Number> getReturnType()

Description copied from interface: Expression

Gets the return type of this expression.

Returns:

A supertype of any objects returned by Expression.getSingle(Event) and the component type of any arrays returned by Expression.getArray(Event)
