By writing an “annotation processor” I can turn any Java text file into an abstract syntax tree and traverse it using a custom visitor (a subclass of TreePathScanner).
Unfortunately, as I learned, the annotation processors are all run before the compiler’s type-check stage.
What is the easiest way for me to get type information about Java expressions (assuming they are part of a complete, valid Java file)? I don’t want to have to write my own type-checker.
After poking at it for some time, it seems that the answer is “you can’t”. Alas, I must seek an alternative solution. (The Eclipse compiler API looks promising…)
