isAcknowledged

public abstract boolean isAcknowledged()

WriteConcern.UNACKNOWLEDGED

getInsertedCount

public abstract int getInsertedCount()

Returns the number of documents inserted by the write operation.

返回:

the number of documents inserted by the write operation

抛出:

java.lang.UnsupportedOperationException - if the write was unacknowledged.

WriteConcern.UNACKNOWLEDGED

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.

返回:

the number of documents matched by updates in the write operation

抛出:

java.lang.UnsupportedOperationException - if the write was unacknowledged.

另请参阅:

WriteConcern.UNACKNOWLEDGED

getRemovedCount

public abstract int getRemovedCount()

Returns the number of documents removed by the write operation.

返回:

the number of documents removed by the write operation

抛出:

java.lang.UnsupportedOperationException - if the write was unacknowledged.

isModifiedCountAvailable

public abstract boolean isModifiedCountAvailable()

Returns true if the server was able to provide a count of modified documents. If this method returns false (which can happen if the server is not at least version 2.6) then the getModifiedCount method will throw UnsupportedOperationException.

返回:

true if modifiedCount is available

抛出:

java.lang.UnsupportedOperationException - if the write was unacknowledged.

另请参阅:

WriteConcern.UNACKNOWLEDGED, getModifiedCount()

getModifiedCount

public abstract int getModifiedCount()

Returns the number of documents modified by the write operation. This only applies to updates or replacements, and will only count documents that were actually changed; for example, if you set the value of some field , and the field already has that value, that will not count as a modification.

If the server is not able to provide a count of modified documents (which can happen if the server is not at least version 2.6), then this method will throw an UnsupportedOperationException

返回:

the number of documents modified by the write operation

抛出:

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

另请参阅:

WriteConcern.UNACKNOWLEDGED, isModifiedCountAvailable()

getUpserts

public abstract java.util.List<BulkWriteUpsert> getUpserts()

Gets an unmodifiable list of upserted items, or the empty list if there were none.

返回:

a list of upserted items, or the empty list if there were none.

抛出:
