メソッドの詳細

of

public static <M> OptionalMod<M> of(java.lang.String modId)

get

public T get()

If a mod is present in this OptionalMod, returns the value, otherwise throws NoSuchElementException.

戻り値:

the modobject held by this OptionalMod

例外:

java.util.NoSuchElementException - if there is no modobject present

関連項目:

Optional.isPresent()

getModId

public java.lang.String getModId()

isPresent

public boolean isPresent()

Return true if there is a mod object present, otherwise false.

戻り値:

true if there is a mod object present, otherwise false

ifPresent

public void ifPresent(java.util.function.Consumer<? super T> consumer)

If a mod object is present, invoke the specified consumer with the object, otherwise do nothing.

パラメータ:

consumer - block to be executed if a mod object is present

例外:

java.lang.NullPointerException - if mod object is present and consumer is null

filter

public OptionalMod<T> filter(java.util.function.Predicate<? super T> predicate)

If a mod object is present, and the mod object matches the given predicate, return an OptionalMod describing the value, otherwise return an empty OptionalMod.

パラメータ:

predicate - a predicate to apply to the mod object, if present

戻り値:

an OptionalMod describing the value of this OptionalMod if a mod object is present and the mod object matches the given predicate, otherwise an empty OptionalMod

例外:

java.lang.NullPointerException - if the predicate is null

map

public <U> java.util.Optional<U> map(java.util.function.Function<? super T,? extends U> mapper)

If a mod object is present, apply the provided mapping function to it, and if the result is non-null, return an Optional describing the result. Otherwise return an empty Optional.

型パラメータ:

U - The type of the result of the mapping function

パラメータ:

mapper - a mapping function to apply to the mod object, if present

戻り値:

an Optional describing the result of applying a mapping function to the mod object of this OptionalMod, if a mod object is present, otherwise an empty Optional

例外:

java.lang.NullPointerException - if the mapping function is null

flatMap

public <U> java.util.Optional<U> flatMap(java.util.function.Function<? super T,java.util.Optional<U>> mapper)

If a value is present, apply the provided Optional-bearing mapping function to it, return that result, otherwise return an empty Optional. This method is similar to map(Function), but the provided mapper is one whose result is already an Optional, and if invoked, flatMap does not wrap it with an additional Optional.

型パラメータ:

U - The type parameter to the Optional returned by

パラメータ:

mapper - a mapping function to apply to the mod object, if present the mapping function

戻り値:

the result of applying an Optional-bearing mapping function to the value of this Optional, if a value is present, otherwise an empty Optional

例外:

java.lang.NullPointerException - if the mapping function is null or returns a null result

orElse

public T orElse(T other)

Return the mod object if present, otherwise return other.

パラメータ:

other - the mod object to be returned if there is no mod object present, may be null

戻り値:

the mod object, if present, otherwise other

orElseGet

public T orElseGet(java.util.function.Supplier<? extends T> other)

Return the mod object if present, otherwise invoke other and return the result of that invocation.

パラメータ:

other - a Supplier whose result is returned if no mod object is present

戻り値:

the mod object if present otherwise the result of other.get()

例外:

java.lang.NullPointerException - if mod object is not present and other is null

orElseThrow

public <X extends java.lang.Throwable> T orElseThrow(java.util.function.Supplier<? extends X> exceptionSupplier)
                                              throws X extends java.lang.Throwable

Return the contained mod object, if present, otherwise throw an exception to be created by the provided supplier.

型パラメータ:

X - Type of the exception to be thrown

パラメータ:

exceptionSupplier - The supplier which will return the exception to be thrown

戻り値:

the present mod object

例外:

X - if there is no mod object present

java.lang.NullPointerException - if no mod object is present and exceptionSupplier is null

X extends java.lang.Throwable
