Method Details

get

protected Object[] get(org.bukkit.event.Event e)

Description copied from class: SimpleExpression

This is the internal method to get an expression's values.
To get the expression's value from the outside use SimpleExpression.getSingle(Event) or SimpleExpression.getArray(Event).

Specified by:

get in class SimpleExpression<Object>

Parameters:

e - The event with which this expression is evaluated.

Returns:

An array of values for this event. May not contain nulls.

iterator

@Nullable
public @Nullable Iterator<Object> iterator(org.bukkit.event.Event event)

Description copied from interface: Expression

Returns the same as Expression.getArray(Event) but as an iterator. This method should be overriden by expressions intended to be looped to increase performance.

Specified by:

iterator in interface Expression<Object>

Overrides:

iterator in class SimpleExpression<Object>

Parameters:

event - The event to be used for evaluation

Returns:

An iterator to iterate over all values of this expression which may be empty and/or null, but must not return null elements.

isSingle

public boolean isSingle()

Returns:

true if this expression will ever only return one value at most, false if it can return multiple values.

getReturnType

public Class<?> 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)

init

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

Description copied from interface: SyntaxElement

Called just after the constructor.

Parameters:

expressions - 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)

parseResult - 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.

• ParserInstance.isCurrentEvent(Class...)

toString

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

Parameters:

event - The event to get information from. 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
