| * This method is just to support the compatibility with the previous version. It returns an ASM node of the |
| * member on which the annotation is 'attached'. The type of the node depends on this element. It can be a {@link |
| * org.objectweb.asm.tree.FieldNode}, a {@link org.objectweb.asm.tree.MethodNode} or a |
| * {@link org.objectweb.asm.tree.ClassNode}. It actually checks the current node and returns the first set ones |
| * in this order: field, method, class. |
| * <p/> |
| * The type of the returned object can be determined using the {@link #getElementType} method. However it is |
| * recommended to use one of the following method: {@link #getFieldNode()}, {@link #getMethodNode()} or |
| * {@link #getClassNode()}. |
| * |
| * @return the node. |
