Method Detail

asSerializedClient

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.

Returns:

A serialized view of the MongoDB connections.

getConfig

MongoClientConfiguration getConfig()

Returns the configuration being used by the logical MongoDB connection.

Returns:

The configuration being used by the logical MongoDB connection.

getDatabase

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.

Parameters:

name - The name of the existing database.

Returns:

The MongoDatabase.

listDatabaseNames

List<String> listDatabaseNames()

Returns a list of database names.

Returns:

A list of available database names.

listDatabases

@Deprecated
List<String> listDatabases()

Deprecated. Use the listDatabaseNames() method instead.

Returns a list of database names.

Returns:

A list of available database names.

restart

MongoIterator<Document> restart(DocumentAssignable cursorDocument)
                                throws IllegalArgumentException

Restarts an iterator that was previously saved.

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

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

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

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.
