2011-02-06Untested support for passing array to map-registered function.Nat Goodspeed
An array-registered function has no param names, so you can only pass an array: a map would be meaningless. Initial implementation of map-registered functions assumed that since you CAN pass a map, you MUST pass a map. But in fact it's meaningful to pass an array as well -- for whatever reason -- and easy to implement, so there you are. Tests to follow.
2011-02-01Replace boost::ptr_map<name, etc> with std::map<name, shared_ptr>.Nat Goodspeed
On Windows, unlike on Mac or Linux, boost::ptr_map<> started insisting on this concept of clonability. In other words, it wants to own a unique instance of the pointee; if you copy a value_type -- even to dereference an iterator! -- it wants to construct a whole new instance of the mapped_type. That's nuts. A std::map<..., boost::shared_ptr<>> has the property I want (the mapped_type goes away when the entry is erased), plus it's willing to pass around the shared_ptr to the same instance of the mapped_type. This change also permits simplifying a couple awkward kludges I'd already had to make to accommodate ptr_map's idiosyncracies.
2011-01-31Fix crash bug in array-style metadata query for nullary functions.Nat Goodspeed
The shortcut way to construct an LLSD array of size n is to assign LLSD() to array[n-1]. That's fine -- as long as you remember not to do it for n == 0.
2011-01-28Extend LLEventAPI to directly call other functions & methods.Nat Goodspeed
Until now, LLEventAPI has only been able to register functions specifically accepting(const LLSD&). Typically you add a wrapper method to your LLEventAPI subclass, register that, have it extract desired params from the incoming LLSD and then call the actual function of interest. With help from Alain, added new LLEventAPI::add() methods capable of registering functions/methods with arbitrary parameter signatures. The code uses boost::fusion magic to implicitly match incoming LLSD arguments to the function's formal parameter list, bypassing the need for an explicit helper method. New add() methods caused an ambiguity with a previous convenience overload. Removed that overload and fixed the one existing usage. Replaced LLEventDispatcher::get() with try_call() -- it's no longer easy to return a Callable for caller to call directly. But the one known use of that feature simply used it to avoid fatal LL_ERRS on unknown function-name string, hence the try_call() approach actually addresses that case more directly. Added indra/common/lleventdispatcher_test.cpp to exercise new functionality.

2009-11-12Introduce LLEventDispatcher::begin()/end() to iterate over (name, desc) pairsNat Goodspeed
for all registered operations. (untested) Introduce LLEventDispatcher::getMetadata(name) query so you can discover, for a given named operation, its query string and required parameters. (untested) Introduce LLEventDispatcher::add() convenience methods allowing you to omit description strings. Fix LLLoginInstance (which uses a non-LLEventAPI LLEventDispatcher) back to description-less add() calls. However, filter LLEventDispatcher::add() methods inherited by LLEventAPI so that an LLEventAPI subclass *must* provide a description string.
2009-11-11Add LLEventAPI class, formalizing the mechanism by which we wrap a C++ APINat Goodspeed
with an event API. In addition to the LLEventPump name on which to listen, LLEventAPI accepts a documentation string for event API introspection. Give every LLEventDispatcher::add() overload a new documentation string parameter for event API introspection. Convert every existing event API to new conventions, introducing suitable documentation strings for the API and each of its operations.
2009-10-09DEV-40930: Added ["change"] key to login-module status events. ChangedNat Goodspeed
existing event calls to use state as "offline" or "online", with "change" indicating the reason for this status event. Changed disconnect() to send state "offline", change "disconnect" -- instead of replaying last auth failure. Changed unit tests accordingly. Changed LLLoginInstance::handleLoginEvent() to use LLEventDispatcher to route calls to handleLoginFailure() et al. Added LLEventDispatcher::get() to allow retrieving Callable by name and testing for empty().
2009-06-19DEV-31980: extract dispatch-by-string-name logic from LLAresListener to newNat Goodspeed
LLEventDispatcher and LLDispatchListener classes. See LLAresListener for example usage.
