Constructor Detail

GraphSesame

public GraphSesame()

Create a Jena Graph, which represents a Sesame in-memory local repository that does not have persistent support, synchroinzation support and inference capability.

GraphSesame

public GraphSesame(boolean inferencing,
                   boolean sync,
                   String fileName,
                   String format,
                   int delay)

Create a Jena Graph, which represents a Sesame in-memory local repository that has the following customizable features. It will firstly create a Sesame repository, then create a Sesame graph from the repository.

Parameters:

inferencing - the Sesame repository supports inference or not.

sync - the the Sesame repository is synchronized or not.

fileName - the name of the file provides the persistent storage. Null means no persistent support required.

format - the RDF data format in the persistent storage.

delay - specifies the time (in milliseconds) to wait after a transaction was commited before writing the changed data to file.

GraphSesame

public GraphSesame(boolean sync,
                   String dir)

Create a Jena Graph, which represents a Sesame native local repository.

Parameters:

sync - the the Sesame repository is synchronized or not.

dir - specifies the directory that can be used by the native sail to store its files.

GraphSesame

public GraphSesame(boolean sync,
                   String driver,
                   String url,
                   String user,
                   String password)

Create a Jena Graph, which represents a Sesame rdbms local repository.

Parameters:

sync - true: the model is synchronized; false: not.

driver - identifies the JDBC (Java Data Base Connectivity) driver that is to be used to access the database.

url - identifies the location of the database through a URL.

user - identifies a username with which Sesame can access the database.

password - identifies a password with which Sesame can access the database.

Method Detail
