Interface Try<T>
-
- Type Parameters:
T
- Value type in the case of success.
- All Superinterfaces:
java.lang.Iterable<T>
,java.io.Serializable
,Value<T>
- All Known Implementing Classes:
Try.Failure
,Try.Success
public interface Try<T> extends Value<T>, java.io.Serializable
The Try control gives us the ability write safe code without focusing on try-catch blocks in the presence of exceptions.The following exceptions are considered to be fatal/non-recoverable:
- InterruptedException
- LinkageError
- ThreadDeath
- VirtualMachineError (i.e. OutOfMemoryError or StackOverflowError)
Important note: Try may re-throw (undeclared) exceptions, e.g. on
get()
. From within a dynamic proxyInvocationHandler
this will lead to anUndeclaredThrowableException
. For more information, please read Dynamic Proxy Classes.
