field: - the field to change

amount: - the value to set

                    AsyncOperationCallback<T> callback)

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

Specified by:

set in interface MorphiumWriter

Parameters:

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
