// This class is used for handling Runfiles for a Bazel target on Windows (e.g. |
|
// the output of targets specified in the data attribute of the target). On |
|
// Linux/macOS, Bazel creates a runfiles tree which contains symlinks to the |
|
// actual runfiles. But on Windows, it only creates a MANIFEST file which |
|
// contains a list of <symlink relative path, absolute symlink target path>. |
|
// Thus one initializes a ManifestFile object with the filepath to a MANIFEST |
|
// file and uses it as a key-value datastore by querying the absolute symlink |
|
// target path with the imaginative symlink relative path. See |
|
// https://github.com/bazelbuild/bazel/issues/4261#issuecomment-350723457 for |
|
// more details. |
