Method Summary
Modifier and TypeMethodDescriptionprotected void
Invoked from the implementation ofMethodInvocation.setReturnValue(Object)
.boolean
Returns true if the method invocation threw a checked exception.<T extends Annotation>
TgetAnnotation
(Class<T> annotationType) Returns an instantiated annotation, or null if the target does not have the indicated annotation.<T extends Throwable>
TgetCheckedException
(Class<T> exceptionType) Retrieves the checked exception assignable to the indicated type, or null if the invocation did not throw a checked exception or the thrown exception is not assignable.The instance on which the method was originally invoked.Returns the method being invoked.<T extends Annotation>
booleanhasAnnotation
(Class<T> annotationType) Checks to see if the target has an annotation of the given type.proceed()
Proceed with the method invocation, either chaining into the nextMethodAdvice
added to the method, or ultimately into the actual method implementation.protected abstract void
This is implemented in a runtime-generated subclass.void
rethrow()
If the invocation threw a checked exception, then this method throws that exception wrapped as the cause of a new RuntimeException.setCheckedException
(Exception exception) Sets the checked exception; this can be used to indicate failure for the method, or to cancel the thrown exception (by setting the exception to null).Methods inherited from class java.lang.Object

rethrow
Description copied from interface:MethodInvocationResult
If the invocation threw a checked exception, then this method throws that exception wrapped as the cause of a new RuntimeException. Otherwise, this method does nothing.- Specified by:
rethrow
in interfaceMethodInvocationResult
-
didThrowCheckedException
Description copied from interface:MethodInvocationResult
Returns true if the method invocation threw a checked exception.- Specified by:
didThrowCheckedException
in interfaceMethodInvocationResult
-
getCheckedException
Description copied from interface:MethodInvocationResult
Retrieves the checked exception assignable to the indicated type, or null if the invocation did not throw a checked exception or the thrown exception is not assignable.- Specified by:
getCheckedException
in interfaceMethodInvocationResult
-
getInstance
Description copied from interface:MethodInvocation
The instance on which the method was originally invoked.- Specified by:
getInstance
in interfaceMethodInvocation
-
getInstanceContext
- Specified by:
getInstanceContext
in interfaceMethodInvocation
-
proceed
Description copied from interface:MethodInvocation
Proceed with the method invocation, either chaining into the nextMethodAdvice
added to the method, or ultimately into the actual method implementation. The method may throw a checked exception, which will be caught and be reported asMethodInvocationResult.didThrowCheckedException()
.- Specified by:
proceed
in interfaceMethodInvocation
- Returns:
- this method invocation, for a fluent API
-
setCheckedException
Description copied from interface:MethodInvocation
Sets the checked exception; this can be used to indicate failure for the method, or to cancel the thrown exception (by setting the exception to null).- Specified by:
setCheckedException
in interfaceMethodInvocation
- Parameters:
exception
- new checked exception, or null- Returns:
- this method invocation, for a fluent API
-
hasAnnotation
Description copied from interface:AnnotationAccess
Checks to see if the target has an annotation of the given type.- Specified by:
hasAnnotation
in interfaceAnnotationAccess
-
getAnnotation
Description copied from interface:AnnotationAccess
Returns an instantiated annotation, or null if the target does not have the indicated annotation.- Specified by:
getAnnotation
in interfaceAnnotationAccess
-
getMethod
Description copied from interface:MethodInvocation
Returns the method being invoked.- Specified by:
getMethod
in interfaceMethodInvocation
-
proceedToAdvisedMethod
This is implemented in a runtime-generated subclass.
