@Slice

<- Return

Identifies a section of a method to search for injection points.

Parameters:

  • from - Specifies the start of the slice region. It requires an @At.
  • id - Specifies the identifier for the slice, which is used by @At#slice.
  • to - Specifies the end of the slice region. It too requires an @At.

Usage: Say your target method has calls the same method multiple times, and you want to inject right after one of them. Instead of using ordinal, you can slice the method so that the injector's injection point will only be searched after the injection point in from is found.

public void target() {
	Dummy.getInstance().foo();
	[...]
	Dummy.getInstance().foo();
	[...]
	Dummy.getInstance().bar();
	Dummy.getInstance().foo();
	[...]
	Dummy.getInstance().foo();
}

In this example, if I'd like to inject after the call to foo after bar, the slice would look like @Slice(from = @At(value = "INVOKE", target = "Lnet/example/Dummy;bar()V")). The complete @Inject annotation would look like @Inject(method = "target()V", at = @At(value = "INVOKE", target = "Lnet/example/Dummy;foo()V"), slice = @Slice(from = @At(value = "INVOKE", target = "Lnet/example/Dummy;bar()V"))).
