public class ApplicationResourceManager
Manages a set of ApplicationResource
s, can load and store the
resources at any time.
The ApplicationResource
s are organized in a Map
. Each
resource is associated with a unique key. This key is used to determine, which
stream of bytes belongs to which resource. If data is loaded, the byte-streams
for missing resources will be stored in a buffer that is read as soon as
a missing resource is registered. Additional resources are ignored.
Note that there is no order how the resources are stored in the file.
