ClassDescriptionAbstract base class for
BindingSetimplementations, providing a.o.Base class forTupleQueryResultHandlers with dummy implementations of all methods.A named value binding.A BindingSet is a set of named value bindings, which is used a.o.An interface that indicates that this QueryResultHandler is capable of handling boolean results using theQueryResultHandler.handleBoolean(boolean)method.An exception that can be thrown by an BooleanQueryResultHandler when it encounters an unrecoverable error.Represents a dataset against which operations can be evaluated.A representation of a query result as a sequence ofStatementobjects.An exception indicating that a string could not be parsed into an operation of the expected type by the parser.An exception indicating that a query could not be processed by the query parser, typically due to syntax errors.A BindingSet is a set of named value bindings, which is used a.o.An operation (e.g.A query on a repository that can be formulated in one of the supported query languages (for example SPARQL).The different types of queries that RDF4J recognizes: boolean queries, graph queries, and tuple queries.An exception indicating that the evaluation of a query failed.An exception indicating that the evaluation of a query has been interrupted, for example because it took too long to complete.A type-safe enumeration for RDF query languages such asQueryLanguage.SPARQL.QueryResult<T>Super type of all query result types (TupleQueryResult, GraphQueryResult, etc.).The super class of all handlers for processing query results.The super class of exceptions originating fromQueryResultHandlerimplementations.Utility methods related to query results.A representation of a variable-binding query result as a sequence ofBindingSetobjects.An interface defining methods related to handling sequences of Solutions.An exception that can be thrown by an TupleQueryResultHandler when it encounters an unrecoverable error.A RuntimeException indicating that a specific query language is not supported.An update operation on a repository that can be formulated in one of the supported query languages (for example SPARQL).An exception indicating that the execution of an update failed.
