Constructor Detail

BaseWriteOperation

public BaseWriteOperation(MongoNamespace namespace,
                  boolean ordered,
                  WriteConcern writeConcern)

Construct an instance

Parameters:

namespace - the database and collection namespace for the operation.

ordered - whether the writes are ordered.

writeConcern - the write concern for the operation.

Method Detail

getNamespace

public MongoNamespace getNamespace()

Gets the namespace of the collection to write to.

Returns:

the namespace

getWriteConcern

public WriteConcern getWriteConcern()

Gets the write concern to apply

Returns:

the write concern

isOrdered

public boolean isOrdered()

Gets whether the writes are ordered. If true, no more writes will be executed after the first failure.

Returns:

whether the writes are ordered
