// Resource Manager exposes an assembly's resources to an application for

// user-visible message. Create a set of resource files listing a name
|
|
// for a message and its value, compile them using ResGen, put them in
|
|
// an appropriate place (your assembly manifest(?)), then create a Resource
|
|
// Manager and query for the name of the message you want. The Resource

|
// Manager will use CultureInfo.GetCurrentUICulture() to look

// basename.culture name.resources

// Refactoring Notes
|
|
// -----------------
|
|
// In Feb 08, began first step of refactoring ResourceManager to improve
|
|
// maintainability (sd changelist 3012100). This resulted in breaking
|
|
// apart the InternalGetResourceSet "big loop" so that the file-based
|
|
// and manifest-based lookup was located in separate methods.
|
|
// In Apr 08, continued refactoring so that file-based and manifest-based
|
|
// concerns are encapsulated by separate classes. At construction, the
|
|
// ResourceManager creates one of these classes based on whether the
|
|
// RM will need to use file-based or manifest-based resources, and
|
|
// afterwards refers to this through the interface IResourceGroveler.
|
|
//
|
|
// Serialization Compat: Ideally, we could have refactored further but
|
|
// this would have broken serialization compat. For example, the
|
|
// ResourceManager member UseManifest and UseSatelliteAssem are no
|
|
// longer relevant on ResourceManager. Similarly, other members could
|
|
// ideally be moved to the file-based or manifest-based classes
|
|
// because they are only relevant for those types of lookup.
|
|
//
|
|
// Solution now / in the future:
|
|
// For now, we simply use a mediator class so that we can keep these
|
|
// members on ResourceManager but allow the file-based and manifest-
|
|
// based classes to access/set these members in a uniform way. See
|
|
// ResourceManagerMediator.
|
|
// We encapsulate fallback logic in a fallback iterator class, so that
|
|
// this logic isn't duplicated in several methods.
|
|
//
|
|
// In the future, we can look into either breaking serialization if we
|
|
// decide this doesn't make sense for ResourceManager (i.e. how common
|
|
// is the scenario), manually make serialization work by providing
|
|
// appropriate OnSerialization, Deserialization methods. We can also
|
|
// look into further factoring and better design of IResourceGroveler
|
|
// interface to accommodate unused parameters that don't make sense
|
|
// for either file-based or manifest-based lookup paths.
|
|
//
|
|
// Benefits of this refactoring:
|
|
// - Makes it possible to understand what the ResourceManager does,
|
|
// which is key for maintainability.
|
|
// - Makes the ResourceManager more extensible by identifying and
|
|
// encapsulating what varies
|
|
// - Unearthed a bug that's been lurking a while in file-based
|
|
// lookup paths for InternalGetResourceSet if createIfNotExists is
|
|
// false.
|
|
// - Reuses logic, e.g. by breaking apart the culture fallback into
|
|
// the fallback iterator class, we don't have to repeat the
|
|
// sometimes confusing fallback logic across multiple methods
|
|
// - Fxcop violations reduced to 1/5th of original count. Most
|
|
// importantly, code complexity violations disappeared.
|
|
// - Finally, it got rid of dead code paths. Because the big loop was
|
|
// so confusing, it masked unused chunks of code. Also, dividing
|
|
// between file-based and manifest-based allowed functionaliy
|
|
// unused in silverlight to fall out.
|
|
//
|
|
// Note: this type is integral to the construction of exception objects,
|
|
// and sometimes this has to be done in low memory situtations (OOM) or
|
|
// to create TypeInitializationExceptions due to failure of a static class
|
|
// constructor. This type needs to be extremely careful and assume that
|
|
// any type it references may have previously failed to construct, so statics
|
|
// belonging to that type may not be initialized. FrameworkEventSource.Log
|
|
// is one such example.
