方法概要

限定符和类型	方法和说明
Try<Exception>	failed() Inverts this `Try`.
Try<T>	filter(java.util.function.Predicate<T> p) Converts this to a `Failure` if the predicate is not satisfied.
<U> Try<U>	flatMap(java.util.function.Function<T,Try<U>> f) Returns the given function applied to the value from this `Success` or returns this if this is a `Failure`.
Try<T>	foreach(java.util.function.Consumer<T> f) Applies the given function `f` if this is a `Success`, otherwise returns `Unit` if this is a `Failure`.
T	get() Returns the value from this `Success` or throws the exception if this is a `Failure`.
boolean	isFailure() Returns `true` if the `Try` is a `Failure`, `false` otherwise.
boolean	isSuccess() Returns `true` if the `Try` is a `Success`, `false` otherwise.
<U> Try<U>	map(java.util.function.Function<T,U> f) Maps the given function to the value from this `Success` or returns this if this is a `Failure`.
Try<T>	onException(java.util.function.Consumer<Exception> f)
Try<T>	recover(java.util.function.Function<Exception,T> f) Applies the given function `f` if this is a `Failure`, otherwise returns this if this is a `Success`.
Try<T>	recoverWith(java.util.function.Function<Exception,Try<T>> f) Applies the given function `f` if this is a `Failure`, otherwise returns this if this is a `Success`.
<U> Try<U>	transform(java.util.function.Function<T,Try<U>> s, java.util.function.Function<Exception,Try<U>> f) Completes this `Try` by applying the function `f` to this if this is of type `Failure`, or conversely, by applying `s` if this is a `Success`.

方法详细资料

isFailure

public boolean isFailure()

从类复制的说明: Try

Returns `true` if the `Try` is a `Failure`, `false` otherwise.

指定者:

isFailure 在类中 Try<T>

isSuccess

public boolean isSuccess()

从类复制的说明: Try

Returns `true` if the `Try` is a `Success`, `false` otherwise.

指定者:

isSuccess 在类中 Try<T>

get

public T get()

从类复制的说明: Try

Returns the value from this `Success` or throws the exception if this is a `Failure`.

指定者:

get 在类中 Try<T>

foreach

public Try<T> foreach(java.util.function.Consumer<T> f)

从类复制的说明: Try

Applies the given function `f` if this is a `Success`, otherwise returns `Unit` if this is a `Failure`.

''Note:'' If `f` throws, then this method may throw an exception.

指定者:

foreach 在类中 Try<T>

flatMap

public <U> Try<U> flatMap(java.util.function.Function<T,Try<U>> f)

从类复制的说明: Try

Returns the given function applied to the value from this `Success` or returns this if this is a `Failure`.

指定者:

flatMap 在类中 Try<T>

map

public <U> Try<U> map(java.util.function.Function<T,U> f)

从类复制的说明: Try

Maps the given function to the value from this `Success` or returns this if this is a `Failure`.

指定者:

map 在类中 Try<T>

filter

public Try<T> filter(java.util.function.Predicate<T> p)

从类复制的说明: Try

Converts this to a `Failure` if the predicate is not satisfied.

指定者:

filter 在类中 Try<T>

recoverWith

public Try<T> recoverWith(java.util.function.Function<Exception,Try<T>> f)

从类复制的说明: Try

Applies the given function `f` if this is a `Failure`, otherwise returns this if this is a `Success`. This is like `flatMap` for the exception.

指定者:

recoverWith 在类中 Try<T>

recover

public Try<T> recover(java.util.function.Function<Exception,T> f)

从类复制的说明: Try

Applies the given function `f` if this is a `Failure`, otherwise returns this if this is a `Success`. This is like map for the exception.

指定者:

recover 在类中 Try<T>

failed

public Try<Exception> failed()

从类复制的说明: Try

Inverts this `Try`. If this is a `Failure`, returns its exception wrapped in a `Success`. If this is a `Success`, returns a `Failure` containing an `UnsupportedOperationException`.

指定者:

failed 在类中 Try<T>

transform

public <U> Try<U> transform(java.util.function.Function<T,Try<U>> s,
                            java.util.function.Function<Exception,Try<U>> f)

从类复制的说明: Try

Completes this `Try` by applying the function `f` to this if this is of type `Failure`, or conversely, by applying `s` if this is a `Success`.

指定者:

transform 在类中 Try<T>

onException

public Try<T> onException(java.util.function.Consumer<Exception> f)

指定者:

onException 在类中 Try<T>
