Resource loading

An apparatus for loading a resource in a software application, the software application comprising an ordered search path identifying at least one of a plurality of resource containers, each of the resource containers having a timestamp and an index in the ordered search path, the apparatus comprising:

• a loading module loading a resource from an originating resource container, the originating resource container having an index in the ordered search path;
• an identification module identifying a set of resource containers in the ordered search path, each of the set of resource containers having an index less than or equal to the index of the originating resource container;
• a generation module generating a cached resource as a copy of the loaded resource, the cached resource comprising the index of the originating resource container and a cached resource timestamp, the cached resource timestamp corresponding to a maximum timestamp of the resource containers in the set of resource containers;
• and
• a marking module marking the cached resource as invalid in response to a determination that a resource container in the set of resource containers has a timestamp later than the cached resource timestamp and the identified resource container comprises the cached resource.

A computer program product for loading a resource in a software application, the software application comprising an ordered search path identifying at least one of a plurality of resource containers, each of the resource containers having a timestamp and an index in the ordered search path, said computer program product comprising:

• a computer usable medium having computer useable program code embodied therewith, the computer useable program code comprising:
• computer usable program code configured to load a resource from an originating resource container, the originating resource container having an index in the ordered search path;
• computer usable program code configured to identify a set of resource containers in the ordered search path, each of the set of resource containers having an index less than or equal to the index of the originating resource container;
• computer usable program code configured to generate a cached resource as a copy of the loaded resource, the cached resource comprising the index of the originating resource container and a cached resource timestamp, the cached resource timestamp corresponding to a maximum timestamp of the resource containers in the set of resource containers;
• and
• computer usable program code configured to mark the cached resource as invalid in response to a determination that a resource container in the set of resource containers has a timestamp later than the cached resource timestamp and the identified resource container comprises the cached resource.
