Re: [ajdt-dev] Question about the AJDT weaver

[Andrew Eisenberg <andrew@xxxxxxxxxxxx>]

What you are talking about is an operation called reconciling.  This
operation calls the compiler just to get the structure of a file and
any compile problems, but doesn't produce byte code.  This happens in
aj files as well as Java files, but the reconciling does not perform
any weaving.  In theory, ajc can do weaving on the fly (the analog
operation to reconciling in this case would be called matching), but
this is not implemented in AJDT.  It would be difficult to ensure that
performance is maintained as the matching occurs.

To answer another question, yes, you can perform a build without doing
a save, but the build will not include the unsaved parts of your
files.  This is quite different from reconciling, though.

Let me know if you need any code snippets.

That question may be more general to Eclipse, but I find it curious that the JDT parses Java files even if they are not saved, but the AJDT does not weave files if all changes are not saved. Thanks again!

I have noticed that the weaver only performs the weaving process when a particular file is saved, as opposed to when it is changed. Is this correct and, if so, how do I get the AJDT weaver to weave aspects into the base-code when a particular change is made in the base-code. Thank you in advance for your help, and please inform me if this is not the correct forum for this question.
