This class represents a format-independent view of a resource file. It holds a collection of resources (TAbstractResource descendants).
Typically, a TResource object is loaded from and written to a stream via format-dependent readers and writers, which are descendants of TAbstractResourceReader and TAbstractResourceWriter, respectively.
Single resources can be added, removed, searched and modified: a resource compiler or editor probably will create resources, set their data, and add them to a TResources object which can then be written to file in the desired format.
This class also provides some class methods to register and find resource readers and writers: these classes, once registered, will be used by a TResources object when it is asked to load or save itself to a stream and the user didn't specify a reader or writer.
| Remark: | Because of the copy-on-write mechanism of TAbstractResource, care should be taken when loading resources, since by default resource data isn't immediately read from the stream: resources hold a reference to the original stream because they need it when their data is requested. For further information, see TResources.LoadFromStream and TResources.LoadFromFile. |
