static LinkedHashSet<ClassNode> |
collectAllInterfacesReverseOrder(ClassNode cNode,
LinkedHashSet<ClassNode> interfaces)
Collects all interfaces of a class node, but reverses the order of the declaration of direct interfaces
of this class node.
|
static LinkedHashSet<ClassNode> |
collectSelfTypes(ClassNode receiver,
LinkedHashSet<ClassNode> selfTypes)
Collects all the self types that a type should extend or implement, given
the traits is implements.
|
static LinkedHashSet<ClassNode> |
collectSelfTypes(ClassNode receiver,
LinkedHashSet<ClassNode> selfTypes,
boolean checkInterfaces,
boolean checkSuper)
Collects all the self types that a type should extend or implement, given
the traits is implements.
|
static String[] |
decomposeSuperCallName(String origName)
Returns the name of a method without the super trait specific prefix.
|
static ClassNode |

findHelper(ClassNode trait) |
static <T> T |
getAsType(Object self,
Class<T> clazz)
Converts a class implementing some trait into a target class.
|
static Method |
getBridgeMethodTarget(Method someMethod)
Reflection API to find the method corresponding to the default implementation of a trait, given a bridge method.
|
static boolean |
hasDefaultImplementation(Method method)
Indicates whether a method in a trait interface has a default implementation.
|
static boolean |
hasDefaultImplementation(MethodNode method)
Indicates whether a method in a trait interface has a default implementation.
|
static boolean |
isAnnotatedWithTrait(ClassNode cNode)
Returns true if the specified class node is annotated with the
Trait interface. |
static boolean |
isBridgeMethod(Method someMethod)
Reflection API to indicate whether some method is a bridge method to the default implementation
of a trait.
|
static boolean |
isTrait(Class clazz)
Returns true if the specified class is a trait.
|
static boolean |
isTrait(ClassNode cNode)
Returns true if the specified class node is a trait.
