Constructor Detail

AllegroSail

public AllegroSail(java.lang.String host,
                   int port,
                   boolean start,
                   java.lang.String name,
                   java.io.File directory,
                   int lookahead,
                   int selectLimit,
                   boolean reindexOnCommit,
                   boolean syncOnInsert)

Create a Sail instance to an AllegroGaph triple store. Each instance is serviced by a separate connection to the server.

Parameters:

host - network host serving AllegroGraph

port - AllegroGraph port

start - whether to start a new server

name - name of the triple store

directory - parent directory of the triple store

lookahead - value for search operations. If less than 1, a default value will be used

selectLimit - the value of the AllegroGraph's select limit parameter. If less than 1, a default value will be used.

reindexOnCommit - when true, re-index the store after each commit

syncOnInsert - when true, synchronize the store after every insert operation

AllegroSail

public AllegroSail(AllegroGraph ag)

Create a Sail instance for an AllegroGraph triple store. The application program creates the AllegroGraph and AllegroGraphConnection instances needed to reach the server. The application program is responsible for disabling the connection and closing the triple store.

Parameters:

ag - an AllegroGraph instance already connected to the server.

Method Detail
