Interface ChangeStreamIterable<TResult>

Type Parameters:

TResult - The type of the result.

All Superinterfaces:

java.lang.Iterable<ChangeStreamDocument<TResult>>, MongoIterable<ChangeStreamDocument<TResult>>

public interface ChangeStreamIterable<TResult>
extends MongoIterable<ChangeStreamDocument<TResult>>

Iterable for change streams.

Note: the ChangeStreamDocument class will not be applicable for all change stream outputs. If using custom pipelines that radically change the result, then the withDocumentClass(Class) method can be used to provide an alternative document format.

Since:

3.6

Method Summary

Modifier and Type	Method and Description
ChangeStreamIterable<TResult>	batchSize(int batchSize) Sets the number of documents to return per batch.
ChangeStreamIterable<TResult>	collation(Collation collation) Sets the collation options
ChangeStreamIterable<TResult>	fullDocument(FullDocument fullDocument) Sets the fullDocument value.
ChangeStreamIterable<TResult>	maxAwaitTime(long maxAwaitTime, java.util.concurrent.TimeUnit timeUnit) Sets the maximum await execution time on the server for this operation.
ChangeStreamIterable<TResult>	resumeAfter(BsonDocument resumeToken) Sets the logical starting point for the new change stream.
ChangeStreamIterable<TResult>	startAtOperationTime(BsonTimestamp startAtOperationTime) The change stream will only provide changes that occurred at or after the specified timestamp.
<TDocument> MongoIterable<TDocument>	withDocumentClass(java.lang.Class<TDocument> clazz) Returns a MongoIterable containing the results of the change stream based on the document class provided.

Method Detail

fullDocument

ChangeStreamIterable<TResult> fullDocument(FullDocument fullDocument)

Sets the fullDocument value.

Parameters:

fullDocument - the fullDocument

Returns:

this

resumeAfter

ChangeStreamIterable<TResult> resumeAfter(BsonDocument resumeToken)

Sets the logical starting point for the new change stream.

Parameters:

resumeToken - the resume token

Returns:

this

batchSize

ChangeStreamIterable<TResult> batchSize(int batchSize)

Sets the number of documents to return per batch.

Specified by:

batchSize in interface MongoIterable<ChangeStreamDocument<TResult>>

Parameters:

batchSize - the batch size

Returns:

this

maxAwaitTime

ChangeStreamIterable<TResult> maxAwaitTime(long maxAwaitTime,
                                           java.util.concurrent.TimeUnit timeUnit)

Sets the maximum await execution time on the server for this operation.

Parameters:

maxAwaitTime - the max await time. A zero value will be ignored, and indicates that the driver should respect the server's default value

timeUnit - the time unit, which may not be null

Returns:

this

collation

ChangeStreamIterable<TResult> collation(@Nullable
                                        Collation collation)

Sets the collation options

A null value represents the server default.

Parameters:

collation - the collation options to use

Returns:

this

withDocumentClass

<TDocument> MongoIterable<TDocument> withDocumentClass(java.lang.Class<TDocument> clazz)

Returns a MongoIterable containing the results of the change stream based on the document class provided.

Type Parameters:

TDocument - the result type

Parameters:

clazz - the class to use for the raw result.

Returns:

the new Mongo Iterable

startAtOperationTime

ChangeStreamIterable<TResult> startAtOperationTime(BsonTimestamp startAtOperationTime)

The change stream will only provide changes that occurred at or after the specified timestamp.

Any command run against the server will return an operation time that can be used here.

The default value is an operation time obtained from the server before the change stream was created.

Parameters:

startAtOperationTime - the start at operation time

Returns:

this
