Constructor Detail

MongoClientImpl

public MongoClientImpl(Client client)

Create a new MongoClient.

Parameters:

client - The client interface for interacting with the database.

MongoClientImpl

public MongoClientImpl(MongoClientConfiguration config)

Create a new MongoClient.

Parameters:

config - The configuration for interacting with MongoDB.

Method Detail

asSerializedClient

public MongoClient asSerializedClient()

Returns a MongoClient instance that shares connections with this MongoClient instance but serializes all of its requests on a single connection.

While the returned MongoClient instance is thread safe it is intended to be used by a single logical thread to ensure requests issued to the MongoDB server are guaranteed to be processed in the same order they are requested.

Creation of the serial instance is lightweight with minimal object allocation and no server interaction.

Overridden to create a new Mongo instance around a SerialClientImpl.

Specified by:

asSerializedClient in interface MongoClient

Returns:

A serialized view of the MongoDB connections.

close

public void close()

Overridden to close the underlying client.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

getClient

public Client getClient()

Returns the client value.

Returns:

The client value.

getConfig

public MongoClientConfiguration getConfig()

Returns the configuration being used by the logical MongoDB connection.

Overridden to return the clients configuration.

Specified by:

getConfig in interface MongoClient

Returns:

The configuration being used by the logical MongoDB connection.

getDatabase

public MongoDatabase getDatabase(String name)

Returns the MongoDatabase with the specified name. This method does not validate that the database already exists in the MongoDB instance.

Overridden to create the named database.

Specified by:

getDatabase in interface MongoClient

Parameters:

name - The name of the existing database.

Returns:

The MongoDatabase.

See Also:

MongoClient.getDatabase(java.lang.String)

listDatabaseNames

public List<String> listDatabaseNames()

Returns a list of database names.

Overridden to issue a listDatabases command against the 'admin' database.

Specified by:

listDatabaseNames in interface MongoClient

Returns:

A list of available database names.

See Also:

MongoClient.listDatabaseNames()

listDatabases

public List<String> listDatabases()

Returns a list of database names.

Specified by:

listDatabases in interface MongoClient

Returns:

A list of available database names.

restart

public MongoIterator<Document> restart(DocumentAssignable cursorDocument)
                                throws IllegalArgumentException

Restarts an iterator that was previously saved.

Specified by:

restart in interface MongoClient

Parameters:

cursorDocument - The document containing the state of the cursor.

Returns:

The restarted iterator.

Throws:

IllegalArgumentException - If the document does not contain a valid cursor state.

restart

public MongoCursorControl restart(StreamCallback<Document> results,
                         DocumentAssignable cursorDocument)
                           throws IllegalArgumentException

Restarts a document stream from a cursor that was previously saved.

Specified by:

restart in interface MongoClient

Parameters:

results - Callback that will be notified of the results of the cursor.

cursorDocument - The document containing the state of the cursor.

Returns:

A MongoCursorControl to control the cursor streaming documents to the caller. This includes the ability to stop the cursor and persist its state.

Throws:

IllegalArgumentException - If the document does not contain a valid cursor state.
