Dear Andy,
Thank you for the clarification.
I am simply trying to learn the syntax and its meaning and
a concise explanation (in the form of a grammar) would have helped.
Cheers,
Jozsef

Hi Jozsef,
There isn't really anything formal I'm afraid. The pointcut parser is
not generated from a grammar file in ajc. The team working on the abc
compiler (alternative implementation of AspectJ) did write a formal
grammar but I think we have diverged from that in recent years (I'm
not totally sure). Did you need it for something specific? Those docs
are getting quite old now and unfortunately we are not finding time to
keep these kinds of area up to date with the implementation.
cheers,
Andy

Hi,
The pattern syntax for AspectJ is given at the bottom of this
webpage (see also below):
http://eclipse.org/aspectj/doc/released/progguide/semantics-pointcuts.html
However, I was unable to find an explanation for this grammar.
Where can I find that ?
For example it is not clear to me what the following means (taken
from the last line from the Pattern Summary):
JavaModifier ...
Pattern Summary
Here is a summary of the pattern syntax used in AspectJ:
MethodPattern =
[ModifiersPattern] TypePattern
[TypePattern . ] IdPattern (TypePattern | ".." , ... )
[ throws ThrowsPattern ]
ConstructorPattern =
[ModifiersPattern ]
[TypePattern . ] new (TypePattern | ".." , ...)
[ throws ThrowsPattern ]
FieldPattern =
[ModifiersPattern] TypePattern [TypePattern . ] IdPattern
ThrowsPattern =
[ ! ] TypePattern , ...
TypePattern =
IdPattern [ + ] [ [] ... ]
| ! TypePattern
| TypePattern && TypePattern
| TypePattern || TypePattern
| ( TypePattern )
IdPattern =
Sequence of characters, possibly with special * and .. wildcards
ModifiersPattern =
[ ! ] JavaModifier ...
Cheers
Jozsef
