init
public boolean init(Expression<?>[] exprs, int matchedPattern, Kleenean isDelayed, SkriptParser.ParseResult parseResult)Description copied from interface:SyntaxElement
Called just after the constructor.- Parameters:
exprs
- 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 matchedisDelayed
- 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.

get
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 useSimpleExpression.getSingle(Event)
orSimpleExpression.getArray(Event)
.- Specified by:
get
in classSimpleExpression<Object>
- Parameters:
e
- The event- Returns:
- An array of values for this event. May not contain nulls.
-
getConvertedExpression
Description copied from class:SimpleExpression
Usually, you want to overrideSimpleExpression.getConvertedExpr(Class[])
. However, it may be useful to override this method if you have an expression with a return type that is unknown until runtime (like variables). Usually, you'll be fine with just the default implementation. This method is final on versions below 2.2-dev36.- Specified by:
getConvertedExpression
in interfaceExpression<Object>
- Overrides:
getConvertedExpression
in classSimpleExpression<Object>
- Parameters:
to
- The desired return type of the returned expression- Returns:
- The converted expression
- See Also:
Converter
,ConvertedExpression
-
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
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 byExpression.getArray(Event)
-
toString
- 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
