+ // all defaulted.
+ //
+ // Here is an example of accessing metadata for a specified property.
+ // ** I don't like the way this works today, so I'm leaving the example out for now.
+
+ /*
+ Areas that need work:
+
+ 1) Generic Metadata: Properties need to have metadata associated with them so that the system can learn more about
+ them. However, this metadata is system specific. I don't want to force everyone to use my metadata, when they will
+ likely need something completely different. Currently the property system is built for our simulation's needs, so
+ this metadata is hardcoded to the types it wants. This needs to be made generic. Perhaps use boost::any or maybe
+ an additional key/value pair component would work. Either way, it would be nice to try to keep the auto-selection of
+ metadata that already exists in the system.
+
+ 2) Extra Type Specification: There has to be a way to derive the type from the functions when you call add_property.
+ It is really ugly to have to specify it every time.
+
+ 2) Algorithms: We currently only have one path based search algorithm. This expects a single matching value and
+ throws otherwise. This is a useful search algorithm as is, but we need more. We need one that returns iterators
+ over all the items found. We need a version of that that returns them as they exist in the system, and one that
+ returns them sorted based on a given criteria. I also imagine there may be other algorithms for processing entire
+ property trees, or sub-trees. For example, we have a serialization algorithm that walks the entire tree and stores
+ the values of all properties. Given the same tree structure, it can re-walk the tree and set the values to their
+ stored values.
+
+ 3) More compile time optimizations: There are a lot of powerful things you can do by creating properties at runtime.
+ However, our experience shows that most properties are simple, and everything about them is known at compile time.
+ There should be some template mechanism we could use for creating this type of property that would reduce the amount
+ of time that is used at runtime to setup the property without reducing the utility of the system to create properties
+ purely at runtime.
+
+ 4) Property Manager Singleton: Currently the property manager is a singleton. This has been extremely helpful in
+ allowing us to build out the full property group tree and access it from anywhere. However, some people have
+ an aversion to this pattern, and there are cases where you may want multiple managers (if you have multiple copies
+ of your data layer, you probably don't want all those copies combined into the same property group tree). We haven't
+ really thought much further on how to do this better and are looking for insights.
+
+ 5) Safe Property Group: This is something I've been toying around with for a while. Currently it is advantagious to
+ get a property group and hold on to it. However, since property groups are retrieved largely as pointers, this can
+ be dangerious. I can't use shared_ptr since the object that it is pointing to may have been created on the stack,
+ and it won't have control over deletion (among other issues). I have a prototype class that wraps the property group
+ and listens to the property manager to see when it is destroyed, but I'm not sure I like that idea (and it is part of
+ our C++/CLI wrapper, so it isn't something I can share).
+
+ 6) Documentation: We currently have doxygen documented objects for this code. If we are going to submit to boost, we
+ would need quickbook docs on top of that that show how to use everything.
+
+ 7) Unit Tests: We currently have an entire set of unit tests for this code, but it uses UnitTest++. We'd need to
+ convert this to Boost::Test to submit it. This shouldn't be too hard.
+
+ Discussion Points:
+
+ 1) Header Files: I'm distributing this as header only. I did this since it simplified initial distribution (I didn't have
+ to get bjam working right away). In house, we build a library. There a lot of things that can be hidden from the user,
+ including defineing the static instances of the singeltons, if we use a library.
+
+ 2) Right now we have several different begin/end function pairs in property_group for accessing the different data in
+ the system. Is that really the best way to do it? Whould we be passing back const references to the collections instead?
+ If we did that, then what dop we do about retrieving a list of all the property names. That is really just keys to a map,
+ but we can hide that complexity from the user using the technique we use now.
+
+ Dreams:
+
+ 1) Events: Wouldn't it be cool if you could hook to an event that was fired whenever a specified property value
+ changed. Since the system is really just wrapping existing function calls, I haven't come up with a way to do this
+ that doesn't add a lot of work to property implementers, and would have high risk of being buggy. Any ideas?
+
+ 2) Thread Safety: Since the system is really just wrapping existing function calls, any thread safety is tied to
+ those function calls. I currently have no way of exposing complex techniques. Any ideas?
