Method Summary

Modifier and Type	Method and Description
boolean	equals(Object o) Deprecated.
Optional<Try<T>>	filter(Predicate<T> predicate) Deprecated. Applies a filter, where a match returns Success and Failure otherwise.
<U> Try<U>	flatMap(ThrowingFunction<? super T,? extends Try<U>,? extends Exception> mapper) Deprecated. Applies a function on two values.
void	forEach(ThrowingConsumer<? super T,? extends Exception> consumer) Deprecated. Accepts a consuming function and applies it to the value if it is a Success.
int	hashCode() Deprecated.
<U> Try<U>	map(ThrowingFunction<? super T,? extends U,? extends Exception> mapper) Deprecated. Applies a function on a value of type Success.
T	orElse(T defaultValue) Deprecated. Returns the value of the Success, or a default value of the same type if this is a Failure.
T	orElseGet(Supplier<? extends T> defaultValue) Deprecated. Returns the value of the Success, or lazily falls back to a supplied value of the same type
<E extends Exception> T	orElseRethrow() Deprecated. Escapes the Try and enters a regular try-catch flow by rethowing the caught exception when a Failure
<X extends Exception,Y extends Exception> T	orElseThrow(Function<X,Y> ExceptionMapper) Deprecated. Escapes the Try and enters a regular try-catch flow
Try<T>	peek(ThrowingConsumer<? super T,? extends Exception> consumer) Deprecated. Same as forEach but returns the Try for further chaining
Try<T>	peekFailure(Consumer<Failure<T>> consumer) Deprecated. Does nothing on Success, but accepts a consumer on Failure
<U> U	recover(Function<? super T,? extends U> successFunc, Function<Exception,? extends U> failureFunc) Deprecated. Accepts two functions, the first applied if Success - returning the value, the other executed if Failure, returning a fallback value.
Either<? extends Exception,T>	toEither() Deprecated. Creates an Either where the Left is the Failure and Right is the Success from this Try
Optional<T>	toOptional() Deprecated. Creates an Optional wrapping the value if Success.

Method Detail

map

public <U> Try<U> map(ThrowingFunction<? super T,? extends U,? extends Exception> mapper)

Deprecated.

Description copied from class: Try

Applies a function on a value of type Success. Returns self if Failure.

Specified by:

map in class Try<T>

Type Parameters:

U - Type of the return value of the function

Parameters:

mapper - Function from T to U with an Exception in the signature

Returns:

a new Try

flatMap

public <U> Try<U> flatMap(ThrowingFunction<? super T,? extends Try<U>,? extends Exception> mapper)

Deprecated.

Description copied from class: Try

Applies a function on two values. Returns Success of the resulting value, or Returns self if Failure. Same as map() but needs a function ending in a Try

Specified by:

flatMap in class Try<T>

Type Parameters:

U - Type of the value to be wrapped in a Try of the function

Parameters:

mapper - Function from T to Try<U> with an Exception in the signature

Returns:

a new Try

filter

public Optional<Try<T>> filter(Predicate<T> predicate)

Deprecated.

Description copied from class: Try

Applies a filter, where a match returns Success and Failure otherwise.

Specified by:

filter in class Try<T>

Parameters:

predicate - Predicate function to determine Success or Failure

Returns:

the same or new try

forEach

public void forEach(ThrowingConsumer<? super T,? extends Exception> consumer)

Deprecated.

Description copied from class: Try

Accepts a consuming function and applies it to the value if it is a Success. Does nothing if Failure.

Specified by:

forEach in class Try<T>

Parameters:

consumer - Consuming function with an Exception in the signature

peek

public Try<T> peek(ThrowingConsumer<? super T,? extends Exception> consumer)

Deprecated.

Description copied from class: Try

Same as forEach but returns the Try for further chaining

Specified by:

peek in class Try<T>

Parameters:

consumer - Consuming function with an Exception in the signature

Returns:

the same Try

peekFailure

public Try<T> peekFailure(Consumer<Failure<T>> consumer)

Deprecated.

Description copied from class: Try

Does nothing on Success, but accepts a consumer on Failure

Specified by:

peekFailure in class Try<T>

Parameters:

consumer - Consuming function with a failure

Returns:

the same Try

orElse

public T orElse(T defaultValue)

Deprecated.

Description copied from class: Try

Returns the value of the Success, or a default value of the same type if this is a Failure. Note that the argument is always evaluated, and this is not lazy (as opposed to orElseGet)

Specified by:

orElse in class Try<T>

Parameters:

defaultValue - default fallback value

Returns:

value

orElseGet

public T orElseGet(Supplier<? extends T> defaultValue)

Deprecated.

Description copied from class: Try

Returns the value of the Success, or lazily falls back to a supplied value of the same type

Specified by:

orElseGet in class Try<T>

Parameters:

defaultValue - lazy default supplier of fallback value

Returns:

value

toOptional

public Optional<T> toOptional()

Deprecated.

Description copied from class: Try

Creates an Optional wrapping the value if Success. Creates an empty Optional if Failure.

Specified by:

toOptional in class Try<T>

Returns:

An Optional

recover

public <U> U recover(Function<? super T,? extends U> successFunc,
                     Function<Exception,? extends U> failureFunc)

Deprecated.

Description copied from class: Try

Accepts two functions, the first applied if Success - returning the value, the other executed if Failure, returning a fallback value. Note that - the first function cannot have an Exception in its signature. - the fallback function must end in a value

Specified by:

recover in class Try<T>

Type Parameters:

U - Type of the value

Parameters:

successFunc - Function handling the Success case

failureFunc - Function handling the Failure case

Returns:

a value of type U

toEither

public Either<? extends Exception,T> toEither()

Deprecated.

Description copied from class: Try

Creates an Either where the Left is the Failure and Right is the Success from this Try

Specified by:

toEither in class Try<T>

Returns:

an Either

orElseThrow

public <X extends Exception,Y extends Exception> T orElseThrow(Function<X,Y> ExceptionMapper)
                                                        throws Y extends Exception

Deprecated.

Description copied from class: Try
