Class ResourceKey
java.lang.Object
org.pentaho.reporting.libraries.resourceloader.ResourceKey
- All Implemented Interfaces:
- Serializable
public final class ResourceKey
- extends Object
- implements Serializable
The key is an unique identifier for the resource. Most of the time, this may be an URL, but other (especially
database based) schemas are possible.
A resource key must provide an 'equals' implementation. ResourceKeys should be implemented as immutable classes, so
that they can be safely stored in collections or on external storages (like caches).
