Constructor Detail

OrientGraphFactory

public OrientGraphFactory(String iURL)

Creates a factory that use default admin credentials and pool with maximum amount of connections equal to amount of CPU cores.

Parameters:

iURL - to the database

OrientGraphFactory

public OrientGraphFactory(String iURL,
                          boolean createPool)

Creates a factory that use default admin credentials and pool with maximum amount of connections equal to amount of CPU cores if needed.

Parameters:

iURL - to the database

createPool - flag which indicates whether pool should be created.

OrientGraphFactory

public OrientGraphFactory(String iURL,
                          String iUser,
                          String iPassword)

Creates a factory with given credentials and pool with maximum amount of connections equal to amount of CPU cores.

If you wish to change pool settings call com.tinkerpop.blueprints.impls.orient.OrientGraphFactory#setupPool(int, int) method.

Parameters:

iURL - to the database

iUser - name of the user

iPassword - of the user

OrientGraphFactory

public OrientGraphFactory(String iURL,
                          String iUser,
                          String iPassword,
                          boolean createPool)

Creates a factory with given credentials and pool with maximum amount of connections equal to amount of CPU cores if that is needed.

If you wish to change pool settings call com.tinkerpop.blueprints.impls.orient.OrientGraphFactory#setupPool(int, int) method.

Parameters:

iURL - to the database

iUser - name of the user

iPassword - of the user

createPool - flag which indicates whether pool should be created.

OrientGraphFactory

public OrientGraphFactory(String iURL,
                          String iUser,
                          String iPassword,
                          OPartitionedDatabasePool pool)

Creates a factory with given credentials also you may pass pool which you already use in "document part" of your application. It is mandatory to use the same pool for document and graph databases.

Parameters:

iURL - to the database

iUser - name of the user

iPassword - password of the user

pool - Pool which is used in "document part" of your application.

Method Detail

close

public void close()

Closes all pooled databases and clear the pool.

drop

public void drop()

Drops current database if such one exists.

getTx

public OrientGraph getTx()

Gets transactional graph with the database from pool if pool is configured. Otherwise creates a graph with new db instance. The Graph instance inherits the factory's configuration.

Returns:

transactional graph

getNoTx

public OrientGraphNoTx getNoTx()

Gets non transactional graph with the database from pool if pool is configured. Otherwise creates a graph with new db instance. The Graph instance inherits the factory's configuration.

Returns:

non transactional graph

getTxGraphImplFactory

public static OrientGraphFactory.OrientGraphImplFactory getTxGraphImplFactory()

setTxGraphImplFactory

public static void setTxGraphImplFactory(OrientGraphFactory.OrientGraphImplFactory factory)

getNoTxGraphImplFactory

public static OrientGraphFactory.OrientGraphImplFactory getNoTxGraphImplFactory()

setNoTxGraphImplFactory

public static void setNoTxGraphImplFactory(OrientGraphFactory.OrientGraphImplFactory factory)

getDatabase

public ODatabaseDocumentTx getDatabase()

Gives new connection to database. If current factory configured to use pool (see setupPool(int, int) method), retrieves connection from pool. Otherwise creates new connection each time.

Automatically creates database if database with given URL does not exist

Shortcut for getDatabase(true)

Returns:

database.

getDatabase

public ODatabaseDocumentTx getDatabase(boolean iCreate,
                                       boolean iOpen)

Gives new connection to database. If current factory configured to use pool (see setupPool(int, int) method), retrieves connection from pool. Otherwise creates new connection each time.

Parameters:

iCreate - if true automatically creates database if database with given URL does not exist

iOpen - if true automatically opens the database

Returns:

database

exists

public boolean exists()

Check if the database with path given to the factory exists.

this api can be used only in embedded mode, and has no need of authentication.

Returns:

true if database is exists

setupPool

public OrientGraphFactory setupPool(int iMin,
                                    int iMax)

Setting up the factory to use database pool instead of creation a new instance of database connection each time.

Parameters:

iMin - minimum size of pool

iMax - maximum size of pool

Returns:

this

getAvailableInstancesInPool

public int getAvailableInstancesInPool()

Returns the number of available instances in the pool.

getCreatedInstancesInPool

public int getCreatedInstancesInPool()

Returns the total number of instances created in the pool.
