 ScheduledThreadPoolExecutor timeoutExecutor,
 Clock clock)

Method Details

stream

public void stream(String documentId,
 String operationId,
 CharSequence documentData,
 Object context)

Description copied from interface: FeedClient

Issues a document operation to the configured cluster(s). If the pipeline and buffers are full, this call will be blocking, ensuring that operations are not produced faster than the can be handled. Transient failures are retried internally by this client. Exactly one callback will always be received for each (completed) call to this.

Specified by:

stream in interface FeedClient

Parameters:

documentId - the document id of the document

operationId - the id to use for this operation, or null to let the client decide an operation id. This id must be unique for every operation. Passing the operation id allows clients to prepare to receive a response for it before issuing the operation to the client.

documentData - the document data as JSON or XML (as specified when using the factory to create the API)

context - a context object which will be accessible in the result of the callback, or null if none

close

public void close()

Description copied from interface: FeedClient

Waits for all results to arrive and closes the FeedClient. Don't call any other method after calling close(). Does not throw any exceptions.

getStatsAsJson

public String getStatsAsJson()

Description copied from interface: FeedClient

Returns stats about the cluster

Specified by:

Returns:

JSON string with information about cluster
