Method Detail

get

public T get()

Gets the result value. If the method invocation was not successful then this will throw the exception that was caught when the method was invoked. This method does not throw checked exceptions. If the failure that caused the method invocation was a checked exception then it will be wrapped in a RuntimeException.

Returns:

the value returned from a method invocation

Throws:

Error - if the method invocation threw an Error

RuntimeException - if the method invocation threw an exception

checkedGet

public T checkedGet()
             throws ExecutionException

Gets the result value. This is just like get() except that it wraps the failures in the checked exception type ExecutionException (just like Futures do).

Returns:

the value returned from a method invocation

Throws:

ExecutionException - if the method invocation threw an exception

getFailure

public Throwable getFailure()

Gets the throwable that caused the method invocation to fail. If the method invocation succeeded then this will return null.

Returns:

the throwable that caused an invocation to fail or null

success

public boolean success()

Returns true if the method invocation was successful (e.g. did not throw).

Returns:

true if the method invocation was successful; false otherwise

failed

public boolean failed()

Returns true if the method invocation failed (e.g. threw).

Returns:

true if the method invocation failed; false otherwise
