Try

sealed class Try<out A>

Representation of an operation that has either succeeded with a result (represented by Success) or failed with an exception (represented by Failure).

Types

Failure	`data class Failure<out A> : Try<A>`
Success	`data class Success<out A> : Try<A>`

Properties

isFailure	Returns `true` iff the Try is a Success. `abstract val isFailure: Boolean`
isSuccess	Returns `true` iff the Try is a Failure. `abstract val isSuccess: Boolean`

Functions

combine	Maps the given function to the values from this Success and other, or returns `this` if this is a Failure or other if other is a Failure. `fun <B, C> combine(other: Try<B>, function: (A, B) -> C): Try<C>`
doOnFailure	Applies the given action to the error if Failure, or does nothing if Success. Returns `this` for chaining. `fun doOnFailure(action: Consumer<Throwable>): Try<A>`
doOnSuccess	Applies the given action to the value if Success, or does nothing if Failure. Returns `this` for chaining. `fun doOnSuccess(action: Consumer<in A>): Try<A>`
flatMap	Returns the given function applied to the value from this Success, or returns `this` if this is a Failure. `fun <B> flatMap(function: (A) -> Try<B>): Try<B>`
getOrThrow	Returns the value if a Success otherwise throws the exception if a Failure. `abstract fun getOrThrow(): A`
map	Maps the given function to the value from this Success, or returns `this` if this is a Failure. `fun <B> map(function: (A) -> B): Try<B>`
throwError	If this is a Failure wrapping an Error then throw it, otherwise return `this` for chaining. `fun throwError(): Try<A>`

Companion Object Functions

on	Executes the given block of code and returns a Success capturing the result, or a Failure if a Throwable is thrown. `fun <T> on(body: () -> T): Try<T>`
