30                  Hidparser: Solaris implementation
31		  _________________________________
32
33
34Report descriptors  are  basically  made of  items.   Items  can  be  'Main'
35items,  'Local' Items  and  'Global' Items. Local and  Global items  differ
36in their  scope. Local  items  hold their value only   within the main item
37in which  they are  defined  while global items retain their values through
38out all main items  unless *redefined*.
39
40Main Items  are  collection,  input, output and  feature and end collection
41items. Each  of  the  main  items are represented by an 'entity_item' struc-
42ture.  Solaris    maintains   global and  local items  as a  linked list of
43entity_attribute   structures  in the 'entity_item' structure.  Since local
44items are specific  to a main  item it   makes  sense to  keep  local items
45with in the main item.  List   of   global  items can't be kept as a single
46global list because they  can   get redefined in any  subsequent main  item
47and Solaris won't be able  to   know what  will  be the value for each main
48item. Hence they also  figure   in the list  maintained  by the entity_item
49structure.
50
51So how do we construct the tree ?
52
53Each main item forms a sibling or child of another main item except for the
54root  main  item which will  always be a Collection main item. Each collect-
55ion item  should be closed  by  an end  collection.  So  root  collection's
56sibling  will be an end  collection. Whatever  input,  output  and  feature
57items  which fall inside  a collection (please  see a collection as '{' and
58end  collection as '}' in  'C' language) will  form a child  of  the parent
59collection  with each of  them  forming  a sibling  of  each  other. i.e if
60an Input  main item comes  first within a  collection  then  it'll form the
61child of  the collection  with the subsequent  main  items  being linked as
62siblings  of each other.  When we reach an end collection, it must form the
63sibling of  the collection.  This applies for nested collections  also. i.e
64if a  collection falls within  another collection, it'll form  a  child  of
65the  parent collection with  the 'input','output' and 'feature' main  items
66falling within  the child collection forming a child  of child  collection.
67Whatever falls  outside the child collection,but inside a parent collection
68will form a sibling of the child collection.
69
70When  hidparser starts, it'll get the raw  descriptor in a structure called
71'hidparser_tok'  structure. Solaris  will  proceed by taking one byte first
72(which sort of forms a header and  indicates  how many  to  follow for each
73item for the 'item data') and then proceeds to take the  value for the item
74(which is the item data). This  'hidparser_tok'  structure  contains a list
75of global and local items. As  and when the parser encounters a global item
76it'll add it to the global item list. The same applies for local items also.
77The only difference is that if  a global item is getting redefined (i.e the
78global item is already present  in the gitem list),  then "the global item"
79(i.e one of the global item) is freed and the new one is put instead. Local
80items can get redefined without  disturbing the earlier  values.  This goes
81on till a main item is encountered. When a  main  item  is encountered  the
82global item list  is copied over to the entity_item structure and the local
83item list will start  where  the global item  list  stops ( in the 'entity_
84attribute' list). Before we start on the next item the local item list will
85be freed (in the hidparser_tok  structure) but the global item list will be
86maintained since their scope is through out the report descriptor.
87
88The two additions which has happened  in this  round  of  changes  are  the
89support for push|pop and delimiter items. 'push' basically asks the  parser
90to copy over the list of  global  items, while  'pop' takes the last pushed
91list as the current one. The entity_attribute_stack forms a stack of global
92item list pointers from which they can be pop-ed on the gitem list.'delimit-
93er'items basically allows you to interpret the data that is  being received
94differently depending on the way you use it and requires the parser to reco-
95gnize only the first 'usage' (which is what Solaris does with my changes).

329'hidparser_ReportDescriptor()' will call  'hidparser_scan()'  first.  Hence
330you will see the  'scanner'  output first.  The scanner will go through the
331first byte and set hidparser_tok_token to the tag|type value. hidparser_tok
332_leng  will be set to size and the 'data' part will be copied to tok_ text.
333'hidparser_ReportDescriptor'  will   call  'hidparser_ItemList()'  to  take
334charge of the rest of the parsing.

362Here  'hidparser_ItemList()'  would have  been called,   which  again calls
363'hidparser_Items()'. The purpose of 'hidparser_Items()'  is to  get through
364all the Items and break when it encounters a main item.  'hidparser_Items()
365will  again  call  'hidparser_GlobalItem()'  and 'hidparser_LocalItem()' to
366make a list of entity attributes in the hidparser_tok structure.
367___________________________________________________________________________
368
369hidparser:      hidparser_GlobalItem:index = 0x0 token = 0x4
370
371___________________________________________________________________________

373The above goes to gitem list.

377hidparser:      scanner: index  = 0x2 ch = 0x9 [ = 0x00001001 = tag[0],
378			type[2], size[1]]
379hidparser:      scanner: parsed_length = 1
380hidparser:      scanner: parsed_text[0] = 0x8,index = 0x3
381hidparser:      scanner: lexical analyzer found 0x9 before translation
382hidparser:      scanner: aindex  = 0x4
383hidparser:      hidparser_LocalItem:index = 0x2 token = 0x8
384___________________________________________________________________________
385
386The above goes to local item list in hidparser_tok_structure.
387___________________________________________________________________________
388
389hidparser:      scanner: index  = 0x4 ch = 0xa1 [= 0x10100001 = tag[a],
390			type[0], size[1]]
391hidparser:      scanner: parsed_length = 1	[ This is a main item ]
392hidparser:      scanner: parsed_text[0] = 0x1,index = 0x5
393hidparser:      scanner: lexical analyzer found 0xa1 before translation
394hidparser:      scanner: aindex  = 0x6
395
396____________________________________________________________________________
397
398Here 'hidparser_Items()' will break and pass the control back to 'hidparser_
399ItemList()' which will call 'hidparser_MainItem()'  to do things specific to
400a main item (like allocating  an entity_item  structure  and returning it in
401curr_ei).  'hidparser_MainItem()' will allocate an entity_item structure and
402copy the gitem list from hidparser tok structure and add the local item list
403to the end of global item list  (in  the  entity_item_attributes  member  of
404entity_item structure).

413hidparser:      scanner: aindex  = 0x8
414hidparser:      Start Collection:cache_ei = 0xcab8d220, curr_ei = 0xcab8d220
415
416____________________________________________________________________________
417
418This forms the root collection.  'cache_ei'  or the cached  entity_item will
419always point to the last collection encountered.  Each entity_item structure
420will have a pointer to the previous collection.  This is basically to remove
421recursion when we support nested collections.  So if I have something like
422
423Collection
424	....
425	Collection
426		....
427		Collection
428		....
429		End Collection
430		....
431	End collection
432	....
433End Collection
434
435and if we assume  that  the parser is currently @ the third Collection item,
436then cache_ei will point to the third collection, it's prev_ei will point to
437the second collection and it's prev_ei will point to the root collection. As
438we move down the first end collection, cache_ei would have changed to second
439collection and so on.

442hidparser:      hidparser_MainItem:index = 0x6 token = 0xa0
443
444____________________________________________________________________________
445
446We encounter  another collection here [ so a nested collection ].  This   'ei'
447will have a  global  item  list (only,  as there are no local items. Remember
448that  we  preserve  global  item list  in  the  hidparser_tok_structure while
449blanking out the local item list as we encounter a main item).

598As can be seen, the tree that Solaris constructs have carried over GI extra
599which is the only difference. But that doesn't make a difference in the way
600we handle data.
601
602There are somethings to be noted at this point. If subsequently we encount-
603er another  global item  which has already been defined (say report size),
604then we  will go to the  global list  maintained in the 'hidparser_tok' st-
605ructure and replace the already existant one  (i.e report size(0x10)  with
606the new one ).
607
608For end collection  main item, we don't attach the global item list to the
609entity item structure.
610
611The rest of the document is a continuation of where we left off the parsing.
612The theory of operation is the same.
