FileManager A FileManager provides access to named file-like resources by opening InputStreams to things in the filing system, by URL (http: and file:) and found by the classloader. It can also load RDF data from such a system resource into an existing model or create a new (Memory-based) model. There is a global FileManager which provide uniform access to system resources: applications may also create specialised FileManagers. A FileManager contains a list of location functions to try: the global FileManger has one {@link LocatorFile}, one {@link LocatorClassLoader} andone {@link LocatorURL}Main operations: *
- loadModel, readModel : URI to model
- open, openNoMap : URI to input stream
- mapURI : map URI to another by {@link LocationMapper}
Utilities:
- readWholeFileAsUTF8
- optional caching of models
A FileManager works in conjunction with a LocationMapper. A {@link LocationMapper} is a set of alternative locations for systemresources and a set of alternative prefix locations. For example, a local copy of a common RDF dataset may be used whenever the usual URL is used by the application. The {@link LocatorFile} also supports the idea of "current directory". @see LocationMapper @see FileUtils
