Interface Summary

Binding	A named value binding.
BindingSet	A BindingSet is a set of named value bindings, which is used a.o.
BooleanQuery
Dataset	Represents a dataset against which queries can be evaluated.
GraphQuery
GraphQueryResult	A representation of a query result as a sequence of Statement objects.
Operation	An operation (e.g.
Query	A query on a Repository that can be formulated in one of the supported query languages (for example SeRQL or SPARQL).
QueryResult<T>	Super type of all query result types (TupleQueryResult, GraphQueryResult, etc.).
TupleQuery
TupleQueryResult	A representation of a variable-binding query result as a sequence of BindingSet objects.
TupleQueryResultHandler	An interface defining methods related to handling sequences of Solutions.
Update	An update operation on a Repository that can be formulated in one of the supported query languages (for example SPARQL).

Class Summary

QueryLanguage	A type-safe enumeration for RDF query languages.
QueryResultUtil	Class offering utility methods related to query results.
TupleQueryResultHandlerBase	Base class for TupleQueryResultHandlers with dummy implementations of all methods.

Exception Summary

IncompatibleOperationException	An exception indicating that a string could not be parsed into an operation of the expected type by the parser.
MalformedQueryException	An exception indicating that a query could not be processed by the query parser, typically due to syntax errors.
QueryEvaluationException	An exception indicating that the evaluation of a query failed.
QueryInterruptedException	An exception indicating that the evaluation of a query has been interrupted, for example because it took too long to complete.
TupleQueryResultHandlerException	An exception that can be thrown by an TupleQueryResultHandler when it encounters an unrecoverable error.
