Method Detail

getStorage

OStorage getStorage()

Returns the underlying storage implementation.

Returns:

The underlying storage implementation

See Also:

OStorage

getStorageInfo

OStorageInfo getStorageInfo()

setUser

void setUser(OSecurityUser user)

Set user for current database instance.

replaceStorage

void replaceStorage(OStorage iNewStorage)

Internal only: replace the storage with a new one.

Parameters:

iNewStorage - The new storage to use. Usually it's a wrapped instance of the current cluster.

resetInitialization

void resetInitialization()

getDatabaseOwner

ODatabaseInternal<?> getDatabaseOwner()

Returns the database owner. Used in wrapped instances to know the up level ODatabase instance.

Returns:

Returns the database owner.

setDatabaseOwner

ODatabaseInternal<?> setDatabaseOwner(ODatabaseInternal<?> iOwner)

Internal. Sets the database owner.

getUnderlying

<DB extends ODatabase> DB getUnderlying()

Return the underlying database. Used in wrapper instances to know the down level ODatabase instance.

Returns:

The underlying ODatabase implementation.

setInternal

void setInternal(ODatabase.ATTRIBUTES attribute,
                 Object iValue)

Internal method. Don't call it directly unless you're building an internal component.

open

@Deprecated
<DB extends ODatabase> DB open(OToken iToken)

Deprecated.

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

Parameters:

iToken - Authentication token

Returns:

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

getSharedContext

OSharedContext getSharedContext()

getMicroOrRegularTransaction

OBasicTransaction getMicroOrRegularTransaction()

The active implicit micro-transaction or active/inactive regular transaction. Use the transaction returned by this method if you are doing "system" things that affect both regular database transactions and implicit storage micro-transactions wrapping non-transactional operations on the database-storage level.

getLocalNodeName

default String getLocalNodeName()

returns the cluster map for current deploy. The keys of the map are node names, the values contain names of clusters (data files) available on the single node.

Returns:

the cluster map for current deploy

getActiveClusterMap

default Map<String,Set<String>> getActiveClusterMap()

returns the cluster map for current deploy. The keys of the map are node names, the values contain names of clusters (data files) available on the single node.

Returns:

the cluster map for current deploy

getActiveDataCenterMap

default Map<String,Set<String>> getActiveDataCenterMap()

returns the data center map for current deploy. The keys are data center names, the values are node names per data center

Returns:

data center map for current deploy

isSharded

default boolean isSharded()

checks the cluster map and tells whether this is a sharded database (ie. a distributed DB where at least two nodes contain distinct subsets of data) or not

Returns:

true if the database is sharded, false otherwise

getEnterpriseEndpoint

default OEnterpriseEndpoint getEnterpriseEndpoint()

Returns:

an endpoint for Enterprise features. Null in Community Edition
