All Implemented Interfaces:

public class AGRepositoryConnection
extends org.openrdf.repository.base.RepositoryConnectionBase
implements org.openrdf.repository.RepositoryConnection, Closeable

Implements the Sesame RepositoryConnection interface for AllegroGraph.

By default, a connection is autoCommit=true. For ACID transactions, a session must be created.

Session Overview

Sessions with AllegroGraph server are used for ACID transactions and also for server code in InitFile and Scripts. See more documentation for Sessions in the AllegroGraph HTTP Protocol and ACID transactions in the AllegroGraph Server documentation.

Operations such as setAutoCommit, addRules, and registerSNAGenerator will spawn a dedicated session in order to perform their duties. Adds and deletes during a session must be committed or rolled back.

A session expires when its idle lifetime is exceeded, freeing up server resources. A session lifetime may be extended by calling ping. A session should be closed when finished.

InitFiles and Scripts are loaded into the server only for sessions. See Scripting in HTTP Protocol and search for "InitFile" in WebView for how to create initFiles.

Starting a session causes http requests to use a new port, which may cause an exception if the client can not access it. See Session Port Setup.

Methods that start a session if not already started:

Methods that affect a session in use: Methods to configure a session before it is started:

Throws:

                              throws org.openrdf.repository.RepositoryException
Registers a predicate mapping from the predicate to a primitive datatype. This can be useful in speeding up query performance and enabling range queries over datatypes.

Once registered, the objects of any data added via this connection that have this predicate will be mapped to the primitive datatype.

For example, registering that predicate <http://example.org/age> is mapped to XMLSchema.INT and adding the triple: <http://example.org/Fred> <http://example.org/age> "24" will result in the object being treated as "24"^^xsd:int.

See mapping overview and POST predicate mapping.

Parameters:
predicate - the predicate URI
primtype - datatype URI
Throws:
org.openrdf.repository.RepositoryException
See Also:
getPredicateMappings()

deletePredicateMapping

public void deletePredicateMapping(org.openrdf.model.URI predicate)
                            throws org.openrdf.repository.RepositoryException

                              throws org.openrdf.repository.RepositoryException
Gets the predicate mappings defined for this connection.

registerDatatypeMapping

public void registerDatatypeMapping(org.openrdf.model.URI datatype,
                                    org.openrdf.model.URI primtype)
                             throws org.openrdf.repository.RepositoryException
Registers a datatype mapping from the datatype to a primitive datatype. This can be useful in speeding up query performance and enabling range queries over user datatypes.

Once registered, the objects of any data added via this connection that have this datatype will be mapped to the primitive datatype.

For example, registering that datatype <http://example.org/usertype> is mapped to XMLSchema.INT and adding the triple: <http://example.org/Fred> <http://example.org/age> "24"^^<http://example.org/usertype> will result in the object being treated as "24"^^xsd:int.

See mapping overview and POST type mapping.

Parameters:
datatype - the user datatype
primtype - the primitive type
Throws:
org.openrdf.repository.RepositoryException
See Also:
getDatatypeMappings()

deleteDatatypeMapping

public void deleteDatatypeMapping(org.openrdf.model.URI datatype)
                           throws org.openrdf.repository.RepositoryException
Deletes any datatype mapping associated with the given datatype.

See mapping overview and DELETE type mapping.

Parameters:
datatype - the user datatype
Throws:
org.openrdf.repository.RepositoryException
See Also:
getDatatypeMappings(), clearMappings()

getDatatypeMappings

public String[] getDatatypeMappings()
                             throws org.openrdf.repository.RepositoryException
Gets the datatype mappings defined for this connection.

See mapping overview and GET type mapping and the Lisp reference for the datatype-mapping function.

Throws:
org.openrdf.repository.RepositoryException
See Also:
deleteDatatypeMapping(URI), clearMappings(), registerDatatypeMapping(URI, URI), getPredicateMappings()

clearMappings

public void clearMappings()
                   throws org.openrdf.repository.RepositoryException
Deletes all user-defined predicate and datatype mappings for this connection, and reestablishes the automatic mappings for primitive datatypes. This is equivalent to clearMappings(false).

See mapping overview and DELETE all mapping for more details.

Throws:
org.openrdf.repository.RepositoryException
See Also:
getDatatypeMappings(), getPredicateMappings()

clearMappings

public void clearMappings(boolean includeAutoEncodedPrimitiveTypes)
                   throws org.openrdf.repository.RepositoryException
Deletes all predicate and user-defined datatype mappings for this connection.

When includeAutoEncodedPrimitiveTypes is true, also deletes the automatic mappings for primitive datatypes; this is rarely what you want to do, as it will cause range queries to perform much less efficiently than when encodings are used; this option can be useful for ensuring literal forms are preserved in the store (there can be precision loss when encoding some literals).

See mapping overview and DELETE all mapping for more details.

org.openrdf.repository.RepositoryException

Throws:
org.openrdf.repository.RepositoryException
See Also:
addRules(InputStream)

Executes an application/x-rdftransaction. This method is useful for bundling add/remove operations into a single request and minimizing round trips to the server. Changes are committed iff the connection is in autoCommit mode. For increased throughput when sending multiple rdftransaction requests, consider using autoCommit=false and committing less frequently .

Parameters:

registerEncodableNamespace

public void registerEncodableNamespace(String namespace,
                                       String format)
                                throws org.openrdf.repository.RepositoryException
Registers an encodable namespace having the specified format.

Registering an encodable namespace enables a more efficient encoding of URIs in a namespace, and generation of unique URIs for that namespace, because its URIs are declared to conform to a specified format; the namespace is thereby bounded in size, and encodable.

The namespace is any valid URIref, e.g.: http://franz.com/ns0

The format is a string using a simplified regular expression syntax supporting character ranges and counts specifying the suffix portion of the URIs in the namespace, e.g: [a-z][0-9]-[a-f]{3}

Generation of unique URIs AGValueFactory.generateURI(String) for the above namespace and format might yield an ID such as: http://franz.com/ns0@@a0-aaa

Note: "@@" is used to concatenate the namespace and id suffix to facilitate efficient recognition/encoding during parsing.

The format can be ambiguous (e.g., "[A-Z]{1,2}[B-C}{0,1}"). We will not check for ambiguity in this first version but can add this checking at a later time.

If the format corresponds to a namespace that is not encodable (it may be malformed, or perhaps it's too large to encode), an exception is thrown.

For more details, see Encoded IDs.

Parameters:
namespace - a valid namespace, a URI ref
format - a valid format for an encodable namespace
Throws:
org.openrdf.repository.RepositoryException
