Class ODatabaseDocumentTxPooled

java.lang.Object

com.orientechnologies.common.listener.OListenerManger<ODatabaseListener>

com.orientechnologies.orient.core.db.document.ODatabaseDocumentTx

com.orientechnologies.orient.core.db.document.ODatabaseDocumentTxPooled

All Implemented Interfaces:

ODatabaseDocument, ODatabase<ORecord>, ODatabaseDocumentInternal, ODatabaseInternal<ORecord>, ODatabasePooled, ODatabaseSchemaAware<ORecord>, OBackupable, Closeable, AutoCloseable

public class ODatabaseDocumentTxPooled
extends ODatabaseDocumentTx
implements ODatabasePooled

Pooled wrapper to the ODatabaseDocumentTx class. Allows to being reused across calls. The close() method does not close the database for real but release it to the owner pool. The database born as opened and will leave open until the pool is closed.

Constructor Detail

ODatabaseDocumentTxPooled

public ODatabaseDocumentTxPooled(ODatabaseDocumentPool iOwnerPool,
                                 String iURL,
                                 String iUserName,
                                 String iUserPassword)

Method Detail

reuse

public void reuse(Object iOwner,
                  Object[] iAdditionalArgs)

Description copied from interface: ODatabasePooled

Reuses current instance.

Specified by:

reuse in interface ODatabasePooled

open

public ODatabaseDocumentTxPooled open(String iUserName,
                                      String iUserPassword)

Description copied from class: ODatabaseDocumentTx

Opens connection to the storage with given user and password.

But we do suggest OPartitionedDatabasePool.acquire() instead. It will make work faster even with embedded database.

Specified by:

open in interface ODatabase<ORecord>

Overrides:

open in class ODatabaseDocumentTx

Parameters:

iUserName - Username to login

iUserPassword - Password associated to the user

Returns:

Current database instance.

open

public ODatabaseDocumentTxPooled open(OToken iToken)

Description copied from class: ODatabaseDocumentTx

Opens a database using an authentication token received as an argument.

Specified by:

open in interface ODatabaseInternal<ORecord>

Overrides:

open in class ODatabaseDocumentTx

Parameters:

iToken - Authentication token

Returns:

The Database instance itself giving a "fluent interface". Useful to call multiple methods in chain.

create

public ODatabaseDocumentTxPooled create()

Description copied from class: ODatabaseDocumentTx

Creates a new database.

Specified by:

create in interface ODatabase<ORecord>

Overrides:

create in class ODatabaseDocumentTx

Returns:

The Database instance itself giving a "fluent interface". Useful to call multiple methods in chain.

create

public <DB extends ODatabase> DB create(String incrementalBackupPath)

Description copied from class: ODatabaseDocumentTx

Creates new database from database backup. Only incremental backups are supported.

Specified by:

create in interface ODatabase<ORecord>

Overrides:

create in class ODatabaseDocumentTx

Type Parameters:

DB - Concrete database instance type.

Parameters:

incrementalBackupPath - Path to incremental backup

Returns:

he Database instance itself giving a "fluent interface". Useful to call multiple methods in chain.

isUnderlyingOpen

public boolean isUnderlyingOpen()

Description copied from interface: ODatabasePooled

Tells if the underlying database is closed.

Specified by:

isUnderlyingOpen in interface ODatabasePooled

isClosed

public boolean isClosed()

Description copied from interface: ODatabase

Checks if the database is closed.

Specified by:

isClosed in interface ODatabase<ORecord>

Overrides:

isClosed in class ODatabaseDocumentTx

Returns:

true if is closed, otherwise false.

isPooled

public boolean isPooled()

Specified by:

isPooled in interface ODatabaseDocument

Overrides:

isPooled in class ODatabaseDocumentTx

Returns:

true if database is obtained from the pool and false otherwise.

close

public void close()

Avoid to close it but rather release itself to the owner pool.

Specified by:

close in interface ODatabase<ORecord>

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class ODatabaseDocumentTx

forceClose

public void forceClose()

Description copied from interface: ODatabasePooled

Force closing the current instance avoiding to being reused.

Specified by:

forceClose in interface ODatabasePooled

checkOpeness

protected void checkOpeness()

Overrides:

checkOpeness in class ODatabaseDocumentTx
