Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`Object`	`getReturnValue()`	The return value from the method invocation.
`<T extends Throwable> T`	`getThrown(Class<T> throwableClass)`	If `isFail()` is true, this method provides access to the actual checked exception that was thrown.
`boolean`	`isFail()`	If true, then the method invocation ended with a checked exception being thrown.
`void`	`rethrow()`	If the invocation threw a checked exception, this method will wrap that exception in a RuntimeException and throw that.

- Method Detail
  - getReturnValue
```
Object getReturnValue()
```
    The return value from the method invocation. This will be null if the method returns null, is a void method, or if a checked exception was thrown by the method.
  - isFail
```
boolean isFail()
```
    If true, then the method invocation ended with a checked exception being thrown.
  - rethrow
```
void rethrow()
```
    If the invocation threw a checked exception, this method will wrap that exception in a RuntimeException and throw that. For most code that doesn't specifically care about the thrown exception, this method should be invoked before continuing on to examine getReturnValue().
  - getThrown
```
<T extends Throwable> T getThrown(Class<T> throwableClass)
```
    If isFail() is true, this method provides access to the actual checked exception that was thrown.
    
    Parameters:
    
    throwableClass - the type of exception to match
    
    Returns:
    
    the exception, if the method invocation threw a checked exception, and the exception is assignable to the provided type. In other cases, null is returned.
