ByteBuddy - Changing the set of types of an existing AgentBuilder to modify a subset of the instrumented...

I have the following case: I'm using ByteBuddy and its Advice which I applied to several methods of a bunch of classes.



Assuming I have the following classes:




  • x.y.z.MyClass1A

  • x.y.z.MyClass2A

  • x.y.z.MyClass1B

  • x.y.z.MyClass2B


To add my Advice to all of these classes, the AgentBuilder is used and the classes are selected using an ElementMatcher: .type(startsWith("x.y.z.MyClass")). Using the builders visit(..) method I apply the Advice.



This works quite fine and, in the end, gives me an instance of ResettableClassFileTransformer. Now, all of the four example classes contains the advice.



Now, I want to change the ElementMatcher to something like this: .type(endsWith("A"))



I want to archive that only the matching classes (in this example ending with 'A') keeps the advice. The classes which are not matching anymore should be resettet to their original state. Furthermore, if there are other classes that are matching the new ElementMatcher, those should also get the Advice applied.



Is this possible using ByteBuddy and its AgentBuilder?

          Can a sorcerer learn a 5th-level spell early by creating spell slots using the Font of Magic feature?

          Image
          28 6 $begingroup$ Per the Font of Magic feature, sorcerer can use Flexible Casting to create 5th-level spell slots at level 7, even though they are not typically available until level 9. You can transform unexpended sorcery points into one spell slot as a bonus action on your turn. The Creating Spell Slots table shows the cost of creating a spell slot of [5th level is 7] If such a sorcerer levels up while still having this 5th-level spell slot, can they choose a 5th-level spell as the spell they gain upon levelling up? The Spellcasting feature states: Additionally, when you gain a level in this class, you can choose one of the sorcerer spells you know and replace it with another spell from the sorcerer spell list, which also must be of a level for which you have spell slots.

          mat-slide-toggle shouldn't change it's state when I click cancel in confirmation window

          Image
          1 When I checked the slide toggle it should work as expected. But when I try to uncheck it there is a confirmation window asking if you are sure. When I click cancel in that confirmation window, still the toggle changes to unchecked, which shouldn't happen. It should stay in the same state. Here is my Html and TS Code // html <mat-slide-toggle (change)="change($event)" [checked]="isChecked()" > To-pay </mat-slide-toggle> TS code: // ts change(e) { if(this.checked) { if(confirm("Are you sure")) { console.log("toggle") } else { e.stopPropagation(); console.log("toggle should not change if I click the cancel button") }
