Examples of com.intellij.psi.PsiManager.findFile()

com.intellij.psi.PsiManager.findFile()
Returns the PSI file corresponding to the specified virtual file. @param file the file for which the PSI is requested. @return the PSI file, or null if file is a directory, an invalid virtual file,or the current project is a dummy or default project.

    final PsiManager psiManager = PsiManager.getInstance(context.getProject());
    final List<VirtualFilePointer> list = fileSet.getFiles();
    for (VirtualFilePointer pointer : list) {
      final VirtualFile file = pointer.getFile();
      if (file != null) {
        final PsiFile psiFile = psiManager.findFile(file);
        if (psiFile != null && psiFiles.contains(psiFile)) {
          continue;
        }
        builder.addFile(file);
