Method Detail

becauseOfNoResult

public static <T> com.atlassian.fugue.Maybe<T> becauseOfNoResult(com.atlassian.fugue.Maybe<?> maybe)

Deprecated.

Will cast the given Maybe to one with the expected parametrisation.

This has to be Maybe.isEmpty() since it is expected to escape on a Maybe.get() call.

Parameters:

maybe - to be casted to the target type

Returns:

the casted Maybe adhering to the taget type

becauseOf

public static <T> com.atlassian.fugue.Maybe<T> becauseOf(String message,
                                                         Object... args)

Deprecated.

Constructs a Maybe which will escape with the given message on a Maybe.get() call.

Parameters:

message - the message used for the escape, may be formatted for application of String.format(String, Object...)

args - the arguments used for formatting the message, may be null

Returns:

the Maybe escaping on realization

becauseOfException

public static <T> com.atlassian.fugue.Maybe<T> becauseOfException(Exception exception)

Deprecated.

Constructs a Maybe which will escape with the given exception on a Maybe.get() call.

Parameters:

exception - the exception to be thrown, will be nested in a RuntimeException if it is checked
