org.jfree.resourceloader.ResourceManager
The resource manager takes care about the loaded resources, performs caching, if needed and is the central instance when dealing with resources. Resource loading is a two-step process. In the first step, the {@link ResourceLoader}accesses the physical storage or network connection to read in the binary data. The loaded {@link ResourceData}carries versioning information with it an can be cached indendently from the produced result. Once the loading is complete, a {@link ResourceFactory} interprets the binary data and produces a Java-Object from it.
Resources are identified by an Resource-Key and some optional loader parameters (which can be used to parametrize the resource-factories). @author Thomas Morgner @see ResourceData @see ResourceLoader @see ResourceFactory
