Method Details

orThrow

public <T extends Throwable> A orThrow(Fn1<? super Throwable, ? extends T> fn)
                                throws T

Description copied from class: Try

If this is a success value, return it. Otherwise, transform the captured failure with fn and throw the result.

Specified by:

orThrow in class Try<A>

Type Parameters:

T - the type of the thrown Throwable

Parameters:

fn - the Throwable transformation

Returns:

possibly the success value

Throws:

T - the transformation output

match

public <R> R match(Fn1<? super Throwable, ? extends R> aFn,
 Fn1<? super A, ? extends R> bFn)

Description copied from interface: CoProduct2

Type-safe convergence requiring a match against all potential types.

Type Parameters:

R - result type

Parameters:

aFn - morphism A -> R

bFn - morphism B -> R

Returns:

the result of applying the appropriate morphism to this coproduct's unwrapped value

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
