getMatchedCount

public abstract int getMatchedCount()

Returns the number of documents matched by updates or replacements in the write operation. This will include documents that matched the query but where the modification didn't result in any actual change to the document; for example, if you set the value of some field, and the field already has that value, that will still count as an update.

true if modifiedCount is available

Returns:

the number of documents modified by the write operation

Throws:

UnsupportedOperationException - if the write was unacknowledged or if no modified count is available
