208 corresponds exactly to when the object is deleted (non-deleted

209 objects are always held permanently in special lists, and deleted

210 objects are never on these lists and never reusable). To handle

211 this, we just have cleanup_specifiers() called periodically

212 (at the beginning of garbage collection); it removes all dead
|

213 objects.

|
|

216 converted to live ones again if the dead object is in a window
|
|
|
217 configuration. Therefore, for windows, "no longer in use"
|
|

218 corresponds to when the window object is garbage-collected.

667 A specifier tag set is an entity that is attached to an instantiator
|
|
|
668 and can be used to restrict the scope of that instantiator to a
|
|
|
669 particular device class or device type and/or to mark instantiators
|
|
|
670 added by a particular package so that they can be later removed.
|
|
|
671
|
|
|
672 A specifier tag set consists of a list of zero of more specifier tags,
|
|
|
673 each of which is a symbol that is recognized by XEmacs as a tag.
|
|
|
674 (The valid device types and device classes are always tags, as are
|
|
|
675 any tags defined by `define-specifier-tag'.) It is called a \"tag set\"
|
|
|
676 (as opposed to a list) because the order of the tags or the number of
|
|
|
677 times a particular tag occurs does not matter.
|
|
|
678
|
|
|
679 Each tag has a predicate associated with it, which specifies whether
|
|
|
680 that tag applies to a particular device. The tags which are device types
|
|
|
681 and classes match devices of that type or class. User-defined tags can
|
|
|
682 have any predicate, or none (meaning that all devices match). When
|
|
|
683 attempting to instance a specifier, a particular instantiator is only
|
|
|
684 considered if the device of the domain being instanced over matches
|
|
|
685 all tags in the tag set attached to that instantiator.
|
|
|
686
|
|
|
687 Most of the time, a tag set is not specified, and the instantiator
|
|
|
688 gets a null tag set, which matches all devices.

2433 DOMAIN should be a window, frame, or device. Other values that are legal

2434 as a locale (e.g. a buffer) are not valid as a domain because they do not
|
|

2435 provide enough information to identify a particular device (see
|
|
|
2436 `valid-specifier-domain-p'). DOMAIN defaults to the selected window
|
|
|
2437 if omitted.
|
|
|
2438
|
|
|
2439 \"Instantiating\" a specifier in a particular domain means determining
|
|
|
2440 the specifier's \"value\" in that domain. This is accomplished by
|
|
|
2441 searching through the specifications in the specifier that correspond
|
|
|
2442 to all locales that can be derived from the given domain, from specific
|
|
|
2443 to general. In most cases, the domain is an Emacs window. In that case
|
|
|
2444 specifications are searched for as follows:
|
|
|
2445
|
|
|
2446 1. A specification whose locale is the window's buffer;
|
|
|
2447 2. A specification whose locale is the window itself;
|
|
|
2448 3. A specification whose locale is the window's frame;
|
|
|
2449 4. A specification whose locale is the window's frame's device;
|
|
|
2450 5. A specification whose locale is 'global.
|
|
|
2451
|
|
|
2452 If all of those fail, then the C-code-provided fallback value for
|
|
|
2453 this specifier is consulted (see `specifier-fallback'). If it is
|
|
|
2454 an inst-list, then this function attempts to instantiate that list
|
|
|
2455 just as when a specification is located in the first five steps above.
|
|
|
2456 If the fallback is a specifier, `specifier-instance' is called
|
|
|
2457 recursively on this specifier and the return value used. Note,
|
|
|
2458 however, that if the optional argument NO-FALLBACK is non-nil,
|
|
|
2459 the fallback value will not be consulted.
|
|
|
2460
|
|
|
2461 Note that there may be more than one specification matching a particular
|
|
|
2462 locale; all such specifications are considered before looking for any
|
|
|
2463 specifications for more general locales. Any particular specification
|
|
|
2464 that is found may be rejected because its tag set does not match the
|
|
|
2465 device being instantiated over, or because the specification is not
|
|
|
2466 valid for the device of the given domain (e.g. the font or color name
|
|
|
2467 does not exist for this particular X server).
|
|
|
2468
|
|
|
2469 The returned value is dependent on the type of specifier. For example,
|
|
|
2470 for a font specifier (as returned by the `face-font' function), the returned
|
|
|
2471 value will be a font-instance object. For glyphs, the returned value
|
|
|
2472 will be a string, pixmap, or subwindow.
|
|
|
2473

|
|
2474 See also `specifier-matching-instance'.

2492 This function is identical to `specifier-instance' except that a
|
|
|
2493 specification will only be considered if it matches MATCHSPEC.
|
|
|
2494 The definition of \"match\", and allowed values for MATCHSPEC, are
|
|
|
2495 dependent on the particular type of specifier. Here are some examples:
|
|
|
2496
|
|
|
2497 -- For chartable (e.g. display table) specifiers, MATCHSPEC should be a
|
|
|
2498 character, and the specification (a chartable) must give a value for
|
|
|
2499 that character in order to be considered. This allows you to specify,
|
|
|
2500 e.g., a buffer-local display table that only gives values for particular
|
|
|
2501 characters. All other characters are handled as if the buffer-local
|
|
|
2502 display table is not there. (Chartable specifiers are not yet
|
|
|
2503 implemented.)
|
|
|
2504
|
|
|
2505 -- For font specifiers, MATCHSPEC should be a charset, and the specification
|
|
|
2506 (a font string) must have a registry that matches the charset's registry.
|
|
|
2507 (This only makes sense with Mule support.) This makes it easy to choose a
|
|
|
2508 font that can display a particular character. (This is what redisplay
|
|
|
2509 does, in fact.)
