Interface GraphAliases

public interface GraphAliases

The interface for resolving aliases of named graph names. One alias can be defined for a set of graphs and then represents the union of them (with the usual caveat regarding duplicate statements which are not removed). Alias definitions can be added or removed through the linked updater object.
