    This class provides a number of static methods which interact with java.nio.charset.Charset to analyze and transform the strings identifying character encodings.
    CollectionFactory
    CollectionFactory - a central place for allocating sets and maps, mostly so that it's easy to plug in new implementations (eg trove).
    FileManager
     
    FileManagerImpl
    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.
    FileUtils
     
    IteratorCollection
     
    JenaXMLInput
    Create XML input methods.
    LocationMapper
    Alternative locations for URIs.
    Locator
    Interface to things that open streams by some string reference
    LocatorClassLoader
    Deprecated.
    Use StreamManager and LocatorClassLoader from org.apache.jena.riot.system.stream.
    LocatorFile
    Deprecated.
    Use StreamManager and LocatorFile from org.apache.jena.riot.system.stream.
    LocatorURL
    Deprecated.
    Use StreamManager and LocatorHTTP from org.apache.jena.riot.system.stream.
    LocatorZip
    Deprecated.
    Use StreamManager and LocatorZip from org.apache.jena.riot.system.stream.
    Metadata
    Pluck data out of the ether - or failing that, read it from a properties file.
    ModelCollector
     
    ModelCollector.ConcurrentModelCollector
     
    ModelCollector.IntersectionModelCollector
     
    ModelCollector.UnionModelCollector
     
    MonitorGraph
    Graph wrapper which provides normal access to an underlying graph but also maintains a snapshot of the triples it was last known to contain.
    MonitorModel
    Model wrapper which provides normal access to an underlying model but also maintains a snapshot of the triples it was last known to contain.
    OneToManyMap<From,To>
    An extension to a standard map that supports one-to-many mappings: that is, there may be zero, one or many values corresponding to a given key.
    OneToManyMap.Entry<From,To>
    Helper class to implement the Map.Entry interface to enumerate entries in the map
    PrefixMappingUtils
     
    PrintUtil
    A collection of small utilities for pretty printing nodes, triples and associated things.
    ResourceUtils
    General utility methods that operate on RDF resources, but which are not specific to a given model.
    SplitIRI
    Code to split an URI or IRI into prefix and local part.
    SystemUtils
    Note: this has been copied here from ARQ.
    Tokenizer
    A tokenizer, similar to java's StringTokenizer but allows for quoted character strings which can include other separators.
    TypedStream
     
    URIref
    This class provides methods to encode and decode URI References in accordance with http://www.w3.org/TR/charmod/#sec-URIs .
