;;; Commentary:
;;
;; Databases of various forms can all be searched.
;; There are a few types of searches that can be done:
;;
;;   Basic Name Search:
;;    These searches scan a database table  collection for tags based
;;    on name.
;;
;;   Basic Attribute Search:
;;    These searches allow searching on specific attributes of tags,
;;    such as name, type, or other attribute.
;;
;;   Advanced Search:
;;    These are searches that were needed to accomplish some
;;    specialized tasks as discovered in utilities.  Advanced searches
;;    include matching methods defined outside some parent class.
;;
;;    The reason for advanced searches are so that external
;;    repositories such as the Emacs obarray, or java .class files can
;;    quickly answer these needed questions without dumping the entire
;;    symbol list into Emacs for additional refinement searches via
;;    regular semanticdb search.
;;
;; How databases are decided upon is another important aspect of a
;; database search.  When it comes to searching for a name, there are
;; these types of searches:
;;
;;   Basic Search:
;;    Basic search means that tags looking for a given name start
;;    with a specific search path.  Names are sought on that path
;;    until it is empty or items on the path can no longer be found.
;;    Use `semanticdb-dump-all-table-summary' to test this list.
;;    Use `semanticdb-find-throttle-custom-list' to refine this list.
;;
;;   Deep Search:
;;    A deep search will search more than just the global namespace.
;;    It will recurse into tags that contain more tags, and search
;;    those too.
;;
;;   Brute Search:
;;    Brute search means that all tables in all databases in a given
;;    project are searched.  Brute searches are the search style as
;;    written for semantic version 1.x.
;;
;; How does the search path work?
;;
;;  A basic search starts with three parameters:
;;
;;     (FINDME &optional PATH FIND-FILE-MATCH)
;;
;;  FINDME is key to be searched for dependent on the type of search.
;;  PATH is an indicator of which tables are to be searched.
;;  FIND-FILE-MATCH indicates that any time a match is found, the
;;  file associated with the tag should be read into a file.
;;
;;  The PATH argument is then the most interesting argument.  It can
;;  have these values:
;;
;;    nil - Take the current buffer, and use it's include list
;;    buffer - Use that buffer's include list.
;;    filename - Use that file's include list.  If the file is not
;;        in a buffer, see of there is a semanticdb table for it.  If
;;        not, read that file into a buffer.
;;    tag - Get that tag's buffer of file file.  See above.
;;    table - Search that table, and it's include list.
;;
;; Search Results:
;;
;;   Semanticdb returns the results in a specific format.  There are a
;;   series of routines for using those results, and results can be
;;   passed in as a search-path for refinement searches with
;;   semanticdb.  Apropos for semanticdb.*find-result for more.
;;
;; Application:
;;
;; Here are applications where different searches are needed which
;; exist as of semantic 1.4.x
;;
;; eldoc - popup help
;;   => Requires basic search using default path.  (Header files ok)
;; tag jump - jump to a named tag

(define-overloadable-function semanticdb-find-translate-path (path brutish)
  "Translate PATH into a list of semantic tables.
Path translation involves identifying the PATH input argument
in one of the following ways:
  nil - Take the current buffer, and use it's include list
  buffer - Use that buffer's include list.
  filename - Use that file's include list.  If the file is not
      in a buffer, see of there is a semanticdb table for it.  If
      not, read that file into a buffer.
  tag - Get that tag's buffer of file file.  See above.
  table - Search that table, and it's include list.
  find result - Search the results of a previous find.

In addition, once the base path is found, there is the possibility of
each added table adding yet more tables to the path, so this routine
can return a lengthy list.

If argument BRUTISH is non-nil, then instead of using the include
list, use all tables found in the parent project of the table
identified by translating PATH.  Such searches use brute force to
scan every available table.

The return value is a list of objects of type `semanticdb-table' or
284
their children.  In the case of passing in a find result, the result

is returned unchanged.

This routine uses `semanticdb-find-table-for-include' to translate
specific include tags into a semanticdb table.

Note: When searching using a non-brutish method, the list of
included files will be cached between runs.  Database-references
are used to track which files need to have their include lists
refreshed when things change.  See `semanticdb-ref-test'.

Note for overloading:  If you opt to overload this function for your
major mode, and your routine takes a long time, be sure to call

 (semantic-throw-on-input 'your-symbol-here)

so that it can be called from the idle work handler."
