Modifier and Type	Method	Description
protected org.bukkit.inventory.ItemStack[]	get(org.bukkit.event.Event e)	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).
Class<? extends org.bukkit.inventory.ItemStack>	getReturnType()	Gets the return type of this expression.
boolean	init(Expression<?>[] vars, int matchedPattern, Kleenean isDelayed, SkriptParser.ParseResult parser)	Called just after the constructor.
boolean	isLoopOf(String s)	Checks whether the given 'loop-...' expression should match this loop, e.g.
boolean	isSingle()
@Nullable Iterator<org.bukkit.inventory.ItemStack>	iterator(org.bukkit.event.Event e)	Returns the same as Expression.getArray(Event) but as an iterator.

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.

ParserInstance.isCurrentEvent(Class...)

get

protected org.bukkit.inventory.ItemStack[] 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<org.bukkit.inventory.ItemStack>

Parameters:

e - The event

Returns:

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

iterator

public @Nullable Iterator<org.bukkit.inventory.ItemStack> iterator(org.bukkit.event.Event e)

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<org.bukkit.inventory.ItemStack>

Overrides:

iterator in class SimpleExpression<org.bukkit.inventory.ItemStack>

Parameters:

e - The event

Returns:

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

getReturnType

public Class<? extends org.bukkit.inventory.ItemStack> 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)

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

isSingle

public boolean isSingle()

Returns:

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

isLoopOf

public boolean isLoopOf(String s)

Description copied from interface: Expression

Checks whether the given 'loop-...' expression should match this loop, e.g. loop-block matches any loops that loop through blocks and loop-argument matches an argument loop.

You should usually just return false as e.g. loop-block will automatically match the expression if its returnType is Block or a subtype of it.

Specified by:

isLoopOf in interface Expression<org.bukkit.inventory.ItemStack>

Overrides:

isLoopOf in class SimpleExpression<org.bukkit.inventory.ItemStack>

Parameters:

s - The entered string

Returns:

Whether this loop matches the given string
