Resolve full qualified type from compiler syntax tree
Aug 10, 2011 9:17 AM
I'm writting a program to perform some analysis on arbitrary Java source code and I need to be able to resolve types that are imported. This is relatively easy if the type is explicitly imported e.g.
List x = null;
then the type of x can be determined to be List.
However if wildcard imports are used e.g.
List x = nulll;
How can I determine what the type of x actually is? I'm using the java compiler API to parse the source code:
CompilationTask task = compiler.getTask(null, null, null, options, null, files);
JavacTask javacTask = (JavacTask) task;
Iterable<? extends CompilationUnitTree> tree = javacTask.parse();
and then scanning the CompilationUnitTree for items of interest.
I suspect I need to execute the analyze phase of the compiler but I can't see that the output of that phase is immediatly useful.
