Javadoc

Checks requested access against an Access Control List. This method relies on finding the ACL data in the relevant portions of FsPermission and AclFeature as implemented in the logic of AclStorage. This method also relies on receiving the ACL entries in sorted order. This is assumed to be true, because the ACL modification methods in AclTransformation sort the resulting entries. More specifically, this method depends on these invariants in an ACL: - The list must be sorted. - Each entry in the list must be unique by scope + type + name. - There is exactly one each of the unnamed user/group/other entries. - The mask entry must not have a name. - The other entry must not have a name. - Default entries may be present, but they are ignored during enforcement.
