Interfaces and classes for handling queries and query results.
InterfaceDescriptionA 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 the
QueryResultHandler.handleBoolean(boolean)method.Represents a dataset against which operations can be evaluated.A representation of a query result as a sequence of
Statementobjects.An operation (e.g.A query on a repository that can be formulated in one of the supported query languages (for example SPARQL).QueryResult<T>Super type of all query result types (TupleQueryResult, GraphQueryResult, etc.).The super class of all handlers for processing query results.A representation of a variable-binding query result as a sequence of
BindingSetobjects.An interface defining methods related to handling sequences of Solutions.An update operation on a repository that can be formulated in one of the supported query languages (for example SPARQL).
ClassDescriptionAbstract base class for
BindingSetimplementations, providing a.o.Base class for
TupleQueryResultHandlers with dummy implementations of all methods.A type-safe enumeration for RDF query languages such as
QueryLanguage.SPARQL.Utility methods related to query results.Deprecated.since 2.0.Deprecated.since 2.0.
EnumDescriptionThe different types of queries that RDF4J recognizes: boolean queries, graph queries, and tuple queries.
ExceptionDescriptionAn exception that can be thrown by an BooleanQueryResultHandler when it encounters an unrecoverable error.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.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.The super class of exceptions originating from
QueryResultHandlerimplementations.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 exception indicating that the execution of an update failed.
