Constructor Details

ConvertedKeyProviderExpression

public ConvertedKeyProviderExpression(KeyProviderExpression<? extends F> source,
 Class<T> to,
 ConverterInfo<? super F,? extends T> info)

ConvertedKeyProviderExpression

public ConvertedKeyProviderExpression(KeyProviderExpression<? extends F> source,
 Class<T>[] toExact,
 Collection<ConverterInfo<? super F,? extends T>> converterInfos,
 boolean performFromCheck)

Method Details

getArray

public T[] getArray(org.bukkit.event.Event event)

Description copied from interface: Expression

Get all the values of this expression. The returned array is empty if this expression doesn't have any values for the given event.

The returned array must not contain any null values.

Do not use this in conditions, use Expression.check(Event, Predicate, boolean) instead.

Specified by:

getArray in interface Expression<F>

Overrides:

getArray in class ConvertedExpression<F,T>

Parameters:

event - The event

Returns:

An array of values of this expression which must neither be null nor contain nulls, and which must not be an internal array.

getAll

public T[] getAll(org.bukkit.event.Event event)

Description copied from interface: Expression

Gets all possible return values of this expression, i.e. it returns the same as Expression.getArray(Event) if Expression.getAnd() is true, otherwise all possible values for Expression.getSingle(Event).

Specified by:

getAll in interface Expression<F>

Overrides:

getAll in class ConvertedExpression<F,T>

Parameters:

event - The event

Returns:

An array of all possible values of this expression for the given event which must neither be null nor contain nulls, and which must not be an internal array.

getSource

public KeyProviderExpression<? extends F> getSource()

Description copied from interface: Expression

Returns the original expression that was parsed, i.e. without any conversions done.

Specified by:

getSource in interface Expression<F>

Overrides:

getSource in class ConvertedExpression<F,T>

Returns:

The unconverted source expression of this expression or this expression itself if it was never converted.

getArrayKeys

@NotNull
public @NotNull String @NotNull [] getArrayKeys(org.bukkit.event.Event event)
                                         throws IllegalStateException

Description copied from interface: KeyProviderExpression

A set of keys, matching the length and order of the immediately-previous Expression.getArray(Event) values array.
This should only be called immediately after a Expression.getArray(Event) invocation, and iff KeyProviderExpression.canReturnKeys() returns true. If it is called without a matching values request (or after a delay) then the behaviour is undefined, in which case:

• the method may throw an error,
• the method may return keys not matching any previous values,
• or the method may return nothing at all.

Specified by:

getArrayKeys in interface KeyProviderExpression<F>

Parameters:

event - The event context

Returns:

A set of keys, of the same length as Expression.getArray(Event)

Throws:

IllegalStateException - If this was not called directly after a Expression.getArray(Event) call or if KeyProviderExpression.canReturnKeys() returns false

getAllKeys

@NotNull
public @NotNull String @NotNull [] getAllKeys(org.bukkit.event.Event event)

Description copied from interface: KeyProviderExpression

A set of keys, matching the length and order of the immediately-previous Expression.getAll(Event) values array.
This should only be called immediately after a Expression.getAll(Event) invocation, and iff KeyProviderExpression.canReturnKeys() returns true. If it is called without a matching values request (or after a delay) then the behaviour is undefined, in which case:

• the method may throw an error,
• the method may return keys not matching any previous values,
• or the method may return nothing at all.

Specified by:

getAllKeys in interface KeyProviderExpression<F>

Parameters:

event - The event context

Returns:

A set of keys, of the same length as Expression.getAll(Event)

canReturnKeys

public boolean canReturnKeys()

Description copied from interface: KeyProviderExpression

Returns whether this expression can return keys.
If this returns false, then KeyProviderExpression.getArrayKeys(Event) and KeyProviderExpression.getAllKeys(Event) should never be called.

Specified by:

canReturnKeys in interface KeyProviderExpression<F>

Returns:

Whether this expression can return keys

areKeysRecommended

public boolean areKeysRecommended()

Description copied from interface: KeyProviderExpression

While all keyed expressions may offer their keys, some may prefer that they are not used unless strictly required (e.g. variables).

Specified by:

areKeysRecommended in interface KeyProviderExpression<F>

Returns:

Whether the caller is recommended to ask for keys after asking for values

change

public void change(org.bukkit.event.Event event,
 Object @NotNull [] delta,
 Changer.ChangeMode mode,
 @NotNull
 @NotNull String @NotNull [] keys)

Description copied from interface: KeyReceiverExpression

An alternative changer method that provides a set of keys as well as a set of values. This is only ever called for Changer.ChangeMode.supportsKeyedChange() safe change modes, where a set of values is provided. (This will never be called for valueless Changer.ChangeMode.DELETE or Changer.ChangeMode.RESET changers, for example.)

Specified by:

change in interface KeyReceiverExpression<F>

Parameters:

event - The current event context

delta - The change values

mode - The key-safe change mode Changer.ChangeMode.SET

keys - The keys, matching the length and order of the values array

isLoopOf

public boolean isLoopOf(String input)

Description copied from interface: Loopable

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 KeyProviderExpression<F>

Specified by:

isLoopOf in interface Loopable<F>

Overrides:

isLoopOf in class ConvertedExpression<F,T>

Parameters:

input - The entered input string (the blank in loop-___)

Returns:

Whether this loop matches the given string
