Method Details

get

protected Long[] get(org.bukkit.event.Event e,
 org.bukkit.entity.Player[] 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!

Overrides:

get in class SimplePropertyExpression<org.bukkit.entity.Player,Long>

Returns:

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

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

convert

public @Nullable Long convert(org.bukkit.entity.Player p)

Description copied from interface: Converter

Converts an object from the given to the desired type.

Specified by:

convert in interface Converter<org.bukkit.entity.Player,Long>

Specified by:

convert in class SimplePropertyExpression<org.bukkit.entity.Player,Long>

Parameters:

p - The object to convert.

Returns:

the converted object

getReturnType

public Class<Long> 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)

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<Long>

Overrides:

acceptChange in class SimpleExpression<Long>

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<Long>

Overrides:

change in class SimpleExpression<Long>

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.

setTime

public boolean setTime(int time)

Description copied from class: SimpleExpression

Sets the time of this expression, i.e. whether the returned value represents this expression before or after the event.

This method will not be called if this expression is guaranteed to be used after a delay (an error will be printed immediately), but will be called if it only can be after a delay (e.g. if the preceding delay is in an if or a loop) as well as if there's no delay involved.

If this method returns false the expression will be discarded and an error message is printed. Custom error messages must be of ErrorQuality.SEMANTIC_ERROR to be printed (NB: Skript.error(String) always creates semantic errors).

This implementation sets the time but returns false.

Specified by:

setTime in interface Expression<Long>

Overrides:

setTime in class SimpleExpression<Long>

Parameters:

time - -1 for past or 1 for future. 0 is never passed to this method as it represents the default state.

Returns:

Whether this expression has distinct time states, e.g. a player never changes but a block can. This should be sensitive for the event (using ParserInstance.isCurrentEvent(Class)).

SimpleExpression.setTime(int, Class, Expression...), SimpleExpression.setTime(int, Expression, Class...)

getPropertyName

protected String getPropertyName()

Specified by:

getPropertyName in class SimplePropertyExpression<org.bukkit.entity.Player,Long>
