Examples of SharedContext

org.apache.wookie.beans.SharedContext
Represents the shared context for a set of widget instances and the data objects that share that context (participants and data). Instances of this class are (currently) a "virtual" object rather than persisted, and are used to tie together the common objects of the shared context at a higher level of abstraction than specific data queries. In future this class could be used to reference other types of data associated with a shared context, for example to handle host/owner (see WOOKIE-66) or could allow us to have a storage model for shared data that is completely separate from the persistence model for the rest of Wookie, for example a tuple store or distributed keystore
org.xhtmlrenderer.layout.SharedContext
The SharedContext is that which is kept between successive layout and render runs. @author empty
