ShutdownListener, MorphiumWriter

public class BufferedMorphiumWriterImpl
extends Object
implements MorphiumWriter, ShutdownListener

User: Stephan Bösebeck Date: 11.03.13 Time: 11:41

Buffered Writer buffers all write requests (store, update, remove...) to mongo for a certain time. After that time the requests are issued en block to mongo. Attention: this is not using BULK-Requests yet!

Beschreibung aus Schnittstelle kopiert: MorphiumWriter

will change an entry in mongodb-collection corresponding to given class object if query is too complex, upsert might not work! Upsert should consist of single and-queries, which will be used to generate the object to create, unless it already exists. look at Mongodb-query documentation as well

Angegeben von:

Parameter:

query - - query to specify which objects should be set

values - - map fieldName->Value, which values are to be set!

upsert - - insert, if it does not exist (query needs to be simple!)

multiple - - update several documents, if false, only first hit will be updated
