                             throws AGHttpException

Deprecated. The stored proc feature and API are experimental, and subject to change in a future release.

Invoke a stored procedure on the AllegroGraph server. The args must already be encoded, and the response is encoded.

Low-level access to the data sent to the server can be done with:

 {@link AGDeserializer#decodeAndDeserialize(String) AGDeserializer.decodeAndDeserialize}(
     callStoredProcEncoded(functionName, moduleName,
         {@link AGSerializer#serializeAndEncode(Object[]) AGSerializer.serializeAndEncode}(args)));
 

If an error occurs in the stored procedure then result will be a two element vector with the first element being the string "_fail_" and the second element being the error message (also a string).

callStoredProc(String, String, Object...) does this encoding, decoding, and throws exceptions for error result.

Parameters:

functionName - stored proc lisp function, for example "addTwo"

moduleName - lisp FASL file name, for example "example.fasl"

argsEncoded - byte-encoded arguments to the stored procedure

Returns:

String byte-encoded response from stored proc

Throws:

AGHttpException - if there is a problem with the request

Since:

v4.2

deleteDuplicates

public void deleteDuplicates(String comparisonMode)
                      throws AGHttpException

Deletes all duplicates from the store.

The comparisonMode determines what will be deemed a "duplicate".

If comparisonMode is "spog", quad parts (s,p,o,g) will all be compared when looking for duplicates.

If comparisonMode is "spo", only the (s,p,o) parts will be compared; the same triple in different graphs will thus be deemed duplicates.

See also the protocol documentation for deleting duplicates

Parameters:

comparisonMode - determines what is a duplicate

Throws:

AGHttpException - if there is a problem with the request

getAllowExternalBlankNodeIds

public boolean getAllowExternalBlankNodeIds()

Returns:

true iff this HTTP/Storage layer allows external blank node ids.

Since:

v4.4

See Also:

setAllowExternalBlankNodeIds(boolean), AGValueFactory.isAGBlankNodeId(String)

setAllowExternalBlankNodeIds

public void setAllowExternalBlankNodeIds(boolean allow)

Enables/Disables an option to support external blank nodes (experimental).

Disabled by default. Enable it from an AGRepositoryConnection using:

conn.prepareHttpRepoClient().setAllowExternalBlankNodeIds(true);

An external blank node is a blank node whose id is not generated by AllegroGraph. Applications should normally request new blank nodes from AllegroGraph [via the AGValueFactory#createBNode() method in the Sesame api, or via the AGModel#createResource() method in the Jena adapter]; this helps to avoid unintended blank node id collisions (particularly in a multi-user setting) and enables blank nodes to be stored more efficiently, etc.

Previously, for applications that did use an external blank node id [such as via AGValueFactory#createBNode("ex") in Sesame, or in Jena via AGModel#createResource(AnonId.create("ex"))] or an external blank node factory [such as ValueFactoryImpl#createBNode() in Sesame or ResourceFactory#createResource() in Jena], there were some issues that arose. When the application tried to add a statement such as [_:ex p a] over HTTP, the AllegroGraph server allocates a new blank node id to use in place of the external blank node id _:ex, so that the actual statement stored is something like [_:bF010696Fx1 p a].

There are 2 issues with this:

1) adding a second statement such as [_:ex q b] in a subsequent request will result in another new bnode id being allocated, so that the statement stored might be [_:bF010696Fx2 q b], and the link between the two statements (that exists client side via blank node _:ex) is now lost.

2) trying to get the statement [_:ex p a] will fail, because the actual statement stored is [_:bF010696Fx1 p a].

Note that these issues arise with external blank node ids because the server does not know their scope, and by default assumes that the scope is limited to the HTTP request in order to avoid blank node conflicts. When AG-allocated blank node ids are used instead, the two issues above do not arise (they are stored as is, and they will be found as expected with a get). In short, AG-allocated blank nodes round-trip, external blank nodes do not.

One workaround for this is to have applications declare that they want external blank nodes to round-trip. An external blank node can exist for the life of an application, and that life can exceed the life of an AllegroGraph server instance, so adding a statement with an external blank node will need to persist the external blank node's id somehow. AllegroGraph doesn't currently allow storing blank nodes with an arbitrary external id, so this workaround converts them to URI's (of the form "urn:x-bnode:id" by default) for storage, and recovers the blank nodes with correct ids when the values are retrieved in queries, so that applications continue to transparently deal with BNodes and see the expected behavior w.r.t. issues 1) and 2) above.

When enabling the workaround described here, the application must take responsibility for using an external blank node factory that avoids blank node conflicts, and must also be willing to incur the additional costs of storing external blank nodes as URIs. When the workaround is disabled (allow=false, the default), the application must avoid using external blank nodes with AG (using AG-allocated blank nodes instead); using external blank node ids when they are not allowed will result in an explanatory exception (as opposed to quietly exhibiting the two problems described above).

This method and approach are experimental and subject to change.

Parameters:

allow - true enables a workaround to support external bnodes

v4.4

getStorableResource

public Resource getStorableResource(Resource r,
                                    AGValueFactory vf)

Returns a storable Resource for the given Resource.

The intent is that the returned resource can be stored in an AG repository, will round-trip if added to and retrieved from the repository, and that the given Resource can be cheaply recreated from the returned resource.

This method simply returns the original resource when it is a URI or a BNode with an AG generated blank node id (these can be stored and will round-trip). For external BNodes (with an id that does not look like it was generated by AG), a URI of the form "urn:x-bnode:id" is returned when the connection allows external blank nodes; otherwise, an IllegalArgumentException is thrown explaining the need to either avoid external blank nodes or enable the workaround for external blank nodes.

This method is intended for use within the AG client library, not for use by applications.

Parameters:

r - a resource

vf - a value factory that can create new store values

Returns:

a storable resource for the given resource

Since:

v4.4

See Also:

getApplicationResource(Resource, AGValueFactory), setAllowExternalBlankNodeIds(boolean)

getStorableValue

public Value getStorableValue(Value v,
                              AGValueFactory vf)

Returns a storable Value for the given Value.

The intent is that the returned value can be stored in an AG repository, will round-trip if added to and retrieved from the repository, and that the given Value can be cheaply recreated from the returned value.

This method simply returns the original value when it is a URI, Literal, or BNode with AG generated blank node id (these can be stored and will round-trip). For external BNodes (with an id that does not look like it was generated by AG), a URI of the form "urn:x-bnode:id" is returned when the connection allows external blank nodes; otherwise, an IllegalArgumentException is thrown explaining the need to either avoid external blank nodes or enable the workaround for external blank nodes.

This method is intended for use within the AG client library, not for use by applications.

Parameters:

v - a value

vf - a value factory that can create new store values

Returns:

a storable value for the given value

v4.4
