Package com.mongodb.client.model.changestream

Class ChangeStreamDocument<TDocument>

java.lang.Object

com.mongodb.client.model.changestream.ChangeStreamDocument<TDocument>

Type Parameters:

TDocument - The type that this collection will encode the fullDocument field into.

public final class ChangeStreamDocument<TDocument>
extends Object

Represents the $changeStream aggregation output document.

Note: this class will not be applicable for all change stream outputs. If using custom pipelines that radically change the change stream result, then an alternative document format should be used.

Since:

3.6

Method Detail

getResumeToken

public BsonDocument getResumeToken()

Returns the resumeToken

Returns:

the resumeToken

getNamespace

@BsonIgnore
@Nullable
public MongoNamespace getNamespace()

Returns the namespace The invalidate operation type does include a MongoNamespace in the ChangeStreamDocument response. The dropDatabase operation type includes a MongoNamespace, but does not include a collection name as part of the namespace.

Returns:

the namespace. If the namespaceDocument is null or if it is missing either the 'db' or 'coll' keys, then this will return null.

getNamespaceDocument

@BsonProperty("ns")
public BsonDocument getNamespaceDocument()

Returns the namespaceDocument The namespaceDocument is a BsonDocument containing the values associated with a MongoNamespace. The 'db' key refers to the database name and the 'coll' key refers to the collection name.

Returns:

the namespaceDocument

Since:

3.8

getDatabaseName

@BsonIgnore
@Nullable
public String getDatabaseName()

Returns the database name

Returns:

the databaseName. If the namespaceDocument is null or if it is missing the 'db' key, then this will return null.

Since:

3.8

getFullDocument

public TDocument getFullDocument()

Returns the fullDocument

Returns:

the fullDocument

getDocumentKey

public BsonDocument getDocumentKey()

Returns a document containing just the _id of the changed document.

For unsharded collections this contains a single field, _id, with the value of the _id of the document updated. For sharded collections, this will contain all the components of the shard key in order, followed by the _id if the _id isn’t part of the shard key.

Returns:

the document key

getClusterTime

@Nullable
public BsonTimestamp getClusterTime()

Gets the cluster time at which the change occurred.

Returns:

the cluster time at which the change occurred

Since:

3.8

Since server release

4.0

getOperationType

public OperationType getOperationType()

Returns the operationType

Returns:

the operationType

getUpdateDescription

public UpdateDescription getUpdateDescription()

Returns the updateDescription

Returns:

the updateDescription
