|
|
\brief Represents a collection of resources.
|
|
|
|
This class can be used to manage a collection of resources represented
|
|
by ResourceItem's. Usually it does never contain two resources with the
|
|
same type \em and ID, since AddResource() replaces an old item with the
|
|
new one, unless explicitly told not to do so. This should only be done
|
|
by ResourceFile, when type and ID of the items are not yet known.
|
|
Asside from the basic vector features like Add/RemoveResource()/
|
|
ResourceAt() and MakeEmpty() a bunch of IndexOf() methods are provided
|
|
and AssimilateResources() which incorporates all resources of another
|
|
container into this one (replacing old resources, if necessary), emptying
|
|
the other one.
|
|
|
|
The ResourceItem's in a container are deleted on destruction, unless
|
|
removed before via RemoveResource(). MakeEmpty() deletes the items as
|
|
well.
