[Adobe-source-devel] Question about code snippet of hash_index

[cee1 <fy...@gm...>]

Hi all,
I'm trying to learn source code of ASL(1.0.42), and find something strange
to me: (I'm not quiet familiar with c++):

(*adobe/table_index.hpp, line 555*)  *typedef closed_hash_set<pointer,
indirect_key_function_type, hasher, key_equal>  index_type;*
provide 4 type arguments to template class closed_hash_set,
but closed_hash_set(*adobe/closed_hash.hpp, line 152*) needs 5 type
arguments.

Any idea?

Thanks
