public class CommitWaitStream
extends AbstractDocumentFilter

A document filter that will wait for a commit before hooking up the upstream DocumentStream. Once connected, this filter is just a passthrough; it's sole purpose is to introduce a sync delay.

Constructor Detail

CommitWaitStream

public CommitWaitStream(org.ojai.DocumentStream upstreamStream,
                        SharedResource<com.mapr.db.impl.BaseJsonTable> sharedTable,
                        com.mapr.fs.proto.Dbserver.CommitContext commitContext)

Constructor.

Parameters:

upstreamStream - the upstream document stream

sharedTable - the table or index we're waiting for

commitContext - the commit context for the table we're waiting for

Method Detail

iterator

public java.util.Iterator<org.ojai.Document> iterator()

Specified by:

iterator in interface java.lang.Iterable<org.ojai.Document>

Specified by:

iterator in interface org.ojai.DocumentStream

Overrides:

iterator in class AbstractDocumentFilter

closeDerived

protected void closeDerived()

Description copied from class: AbstractDocumentStream

Perform whatever steps the derived class requires for closing. Note that the object's lock/monitor will be held, as this is called by the final synchronized AbstractDocumentStream.close() method.

Overrides:

closeDerived in class AbstractDocumentFilter

getQueryPlan

public void getQueryPlan(java.util.List<java.util.Map<java.lang.String,java.lang.Object>> planList)
