Re: [aspectj-users] Help capturing new with primitive types
|
As you probably know, a workaround is to make it into a join point:
public class Malloc {
public static byte[] bytes(int n) { ... }
}
byte[] buffer = Malloc.bytes(someSize);
...
Sometimes scattered code can be normalized somewhat by delegation,
alone, or via delegation create a good join point model for aspects.
This works for things that aren't join points, either because
AspectJ doesn't support that form, or because there is a sequence
of code at issue, e.g.,
byte[] buffer = new byte[someSize];
for (int i = 0; i < someSize; i++) {
buffer[i] = -1;
}
public static byte[] bytes(int n, byte initialValue) { ... }
