Uses of Result in gololang.error

Methods in gololang.error that return Result

Modifier and Type	Method and Description
Result<?,?>	Result.and(Result<?,?> other) Conjunctive chaining.
Result<?,? extends java.lang.Throwable>	Result.andThen(FunctionReference mapper) Same as map or flatMap depending on the type returned by mapper.
Result<?,?>	Result.apply(Result<?,?> other) Apply the function contained is this result to the given result.
static <T,E extends java.lang.Throwable> Result<T,E>	Result.empty() Returns an empty Result.
static <T,E extends java.lang.Throwable> Result<T,E>	Result.error(E throwable) Returns a failed Result.
static <T> Result<T,java.lang.RuntimeException>	Result.fail(java.lang.String message) Returns a failed Result.
Result<T,E>	Result.filter(java.util.function.Predicate<? super T> predicate) If a value is present and matches the given predicate, return a Result describing the value, otherwise return an empty Result.
<U,X extends java.lang.Throwable> Result<U,X>	Result.flatMap(java.util.function.Function<? super T,Result<U,X>> mapper) If a value is present, apply the provided Result-bearing mapping function to it, otherwise return the Result itself.
Result<java.lang.Object,java.lang.Throwable>	Result.flatMap(FunctionReference mapper) Golo compatible version of flatMap.
Result<?,?>	Result.flattened() Remove one level of result.
<U,X extends java.lang.Throwable> Result<U,X>	Result.map(java.util.function.Function<? super T,? extends U> mapper) If a value is present, apply the provided mapping function to it, otherwise return the Result itself.
Result<java.lang.Object,java.lang.Throwable>	Result.map(FunctionReference mapper) Golo compatible version of map.
<X extends java.lang.Throwable> Result<T,X>	Result.mapError(java.util.function.Function<? super E,? extends X> mapper) If this result is an error, apply the provided mapping function to the contained error, otherwise return the Result itself.
static Result<java.lang.Object,java.lang.Throwable>	Result.of(java.lang.Object value) Dynamic polymorphic constructor.
static <T,E extends java.lang.Throwable> Result<T,E>	Result.ok(T value) Returns a valid Result.
static <T,E extends java.lang.Throwable> Result<T,E>	Result.option(java.util.Optional<T> opt) Construct a Result from a Optional.
static <T> Result<T,java.util.NoSuchElementException>	Result.option(java.util.Optional<T> opt, java.lang.String message) Construct a Result from a Optional.
Result<?,?>	Result.or(Result<?,?> other) Disjunctive chaining.
static <T> Result<T,java.lang.Throwable>	Result.trying(java.util.function.Supplier<T> fun) Runs a function that can raise an exception and return a Result.
