/*
|
|
An interface for presenting a tree view of an rdf datasource (or
|
|
database).
|
|
|
|
Any datasource can also support nsIRDFTree. The interface is purely
|
|
syntactic sugar for traversing simple tree where the child relation
|
|
corresponds to the property type nc:child (nc = http://home.netscape.com/NC-rdf#).
|
|
Each leaf is assumed to have a certain predefined set of properties
|
|
such as creationDate, size, lastModificationDate, lastVisitDate, etc.
|
|
|
|
This interface is substantially less general than nsIRDFDataSource,
|
|
but is adequate for bookmarks, the file system, history and a few
|
|
other very commonly used data sources.
