Examples of org.apache.muse.core.Capability

org.apache.muse.core.Capability
Capability is the atomic unit of functional definition for a resource type. A capability class should define a set of data and operations that are closely-related, but do not necessarily make up the entire definition of a resource interface. Users aggregate capabilities into a {@linkplain Resource Resource}, which takes care of delegating requests to the appropriate capabilities at runtime. Most users will only have to interact with the pluggable nature of Muse development through this interface and the <capability/> tag in muse.xml. @author Dan Jemiolo (danj)
