Package org.apache.jena.shared

This package defines some classes common to the Jena API and SPI levels, in particular the JenaException class from which all Jena-specific exceptions hang, and the interface PrefixMapping for translation to and from QNames.

BadURIException	A Jena exception for malformed URIs.
BrokenException	An exception to throw if an internal error is detected.
CannotCreateException
CannotEncodeCharacterException	Exception to throw when a character cannot be encoded into some context for some reason.
CannotReifyException	The exception thrown by reifyAs if a node is bound to bits and pieces of (an)other triple(s).

NoReaderForLangException	Exception to throw when there is no reader with the specified language
NoReasonerSuppliedException	NoReasonerSuppliedException - the exception to throw if a reasoner (spec) was required, but none was given (eg in ModelSpecs).
NoSuchReasonerException	NoSuchReasonerException - the exception to throw when looking up a reasoner fails (in ModelSpec construction).
NotFoundException	Exception thrown when an attempt is made find something and it is not found.
NoWriterForLangException	Exception to throw if there is no writer for the specified language.
OperationDeniedException	Superclass of exceptions of all refusals of operation on a graph.
