Implements IObject. |
|
Clears the list of pending notifications without sending them. Does not affect the hold nesting count. Definition at line 38 of file uniconfgen.cc. |
|
Commits any changes. The default implementation does nothing. Reimplemented from UniConfGen. Definition at line 35 of file unifiltergen.cc. References UniConfGen::commit(). |
|
Call this when a key's value or children have possibly changed. If the hold nesting count is 0, the notification is sent immediately. Otherwise it is added to a pending list for later. Definition at line 69 of file uniconfgen.cc. References UniConfGen::dispatch_delta(), UniConfGen::hold_delta(), UniConfGen::unhold_delta(), and WvStringParm. Referenced by UniClientGen::deltacb(), UniFilterGen::gencallback(), UniMountGen::mountgen(), UniIniGen::refresh(), UniTempGen::set(), UniRegistryGen::set(), UniPStoreGen::set(), and UniMountGen::unmount(). |
|
Immediately sends notification that a key has possibly changed. Takes care of the details of invoking the callback. Note: You probably want to be using delta() instead. Definition at line 62 of file uniconfgen.cc. References WvStringParm. Referenced by UniConfGen::delta(), and UniConfGen::flush_delta(). |
|
Without fetching its value, returns true if a key exists. This is provided because it is often more efficient to test existance than to actually retrieve the value. The default implementation returns !get(key).isnull(). Reimplemented from UniConfGen. Reimplemented in UniSecureGen. Definition at line 59 of file unifiltergen.cc. References UniConfGen::exists(). Referenced by UniSecureGen::exists(). |
|
Flushes the list of pending notifications by sending them. Does not affect the hold nesting count. Definition at line 44 of file uniconfgen.cc. References UniConfGen::dispatch_delta(). Referenced by UniConfGen::unhold_delta(). |
|
Called by inner generator when a key changes. The default implementation calls delta(key). Definition at line 83 of file unifiltergen.cc. References UniConfGen::delta(), and WvStringParm. Referenced by UniFilterGen::setinner(). |
|
Fetches a string value for a key from the registry. If the key doesn't exist, the return value is WvString::null. Reimplemented from UniFilterGen. Definition at line 32 of file unidefgen.cc. References WvString::edit(), and WvFastString::setsize(). |
|
Returns true if a key has children. This is provided because it is often more efficient to test existance than to actually retrieve the keys. The default implementation uses the iterator returned by iterator() to test whether the child has any keys. Subclasses are strongly encouraged to provide a better implementation. Reimplemented from UniConfGen. Reimplemented in UniSecureGen. Definition at line 65 of file unifiltergen.cc. References UniConfGen::haschildren(). Referenced by UniSecureGen::haschildren(). |
|
Pauses notifications until matched with a call to unhold_delta(). While paused, notification events are placed into a pending list. Redundant notifications may be discarded. Use this to safeguard non-reentrant code. Definition at line 23 of file uniconfgen.cc. Referenced by UniMountTreeGen::commit(), UniMountGen::commit(), UniConfGen::delta(), UniClientGen::deltacb(), UniMountTreeGen::exists(), UniMountTreeGen::get(), UniMountTreeGen::haschildren(), UniConfGen::haschildren(), UniMountTreeGen::mountgen(), UniMountGen::mountgen(), UniMountTreeGen::refresh(), UniMountGen::refresh(), UniIniGen::refresh(), UniMountTreeGen::KeyIter::rewind(), UniTempGen::set(), UniClientGen::set(), UniMountTreeGen::unmount(), UniMountGen::unmount(), and UniMountTreeGen::whichmount(). |

Returns the inner generator.

|
Determines if the generator is usable and working properly. The default implementation always returns true. Reimplemented from UniConfGen. Definition at line 71 of file unifiltergen.cc. References UniConfGen::isok(). |
|
Returns an iterator over the children of the specified key. Must not return NULL; consider returning a NullIter instead. The caller takes ownership of the returned iterator and is responsible for deleting it when finished. Implements UniConfGen. Reimplemented in UniSecureGen. Definition at line 77 of file unifiltergen.cc. References UniConfGen::iterator(). Referenced by UniSecureGen::iterator(). |
|
Refreshes information about a key recursively. May discard uncommitted data. The default implementation always returns true. Reimplemented from UniConfGen. Definition at line 41 of file unifiltergen.cc. References UniConfGen::refresh(). |
|
Implements IObject. |
|
Stores a string value for a key into the registry. If the value is WvString::null, the key is deleted. Returns true on success. Implements UniConfGen. Reimplemented in UniReadOnlyGen, and UniSecureGen. Definition at line 53 of file unifiltergen.cc. References UniConfGen::set(), and WvStringParm. Referenced by UniSecureGen::set(). |
|
Sets the callback for change notification. Must not be reimplemented by subclasses. Definition at line 137 of file uniconfgen.cc. References UniConfGenCallback. Referenced by UniMountTreeGen::mountgen(), UniMountGen::mountgen(), UniFilterGen::setinner(), UniCacheGen::UniCacheGen(), UniConfRoot::UniConfRoot(), UniMountTreeGen::unmount(), UniMountGen::unmount(), and UniConfRoot::~UniConfRoot(). |
|
Raises an error condition.

|
Rebinds the inner generator and prepares its callback. The previous generator is NOT destroyed. "inner" must not be null. Definition at line 24 of file unifiltergen.cc. References UniFilterGen::gencallback(), UniConfGen::setcallback(), and UniConfGenCallback. Referenced by UniFilterGen::UniFilterGen(), UniPermGen::UniPermGen(), and UniSecureGen::UniSecureGen(). |
|
Converts a string to an integer. If the string is null or not recognized, return defvalue. This is here to support the common str2int(get(key)). The default implementation recognizes the booleans 'true', 'yes', 'on' and 'enabled' as 1, and 'false', 'no', 'off' and 'disabled' as 0. Definition at line 105 of file uniconfgen.cc. References WvFastString::cstr(), WvFastString::isnull(), and WvStringParm. |
|
Resumes notifications when each hold_delta() has been matched. On resumption, dispatches all pending notifications except those that were destined to watches that were removed. Use this to safeguard non-reentrant code. Definition at line 29 of file uniconfgen.cc. References UniConfGen::flush_delta().
