Constructor Details

MapPolicy

public MapPolicy()

Default constructor. Create unordered unique key map when map does not exist. Use normal update mode when writing map items.

MapPolicy

public MapPolicy(MapOrder order,
 MapWriteMode writeMode)

Create unique key map with specified order when map does not exist. Use specified write mode when writing map items.

This constructor should only be used for server versions < 4.3. MapPolicy(MapOrder,int) is recommended for server versions >= 4.3.

MapPolicy

public MapPolicy(MapOrder order,
 int flags)

Create unique key map with specified order when map does not exist.

Parameters:

order - map order

flags - map write flags. See MapWriteFlags.

MapPolicy

public MapPolicy(MapOrder order,
 int flags,
 boolean persistIndex)

Create unique key map with specified order and persist index flag when map does not exist.

Parameters:

order - map order

flags - map write flags. See MapWriteFlags.

persistIndex - if true, persist map index. A map index improves lookup performance, but requires more storage. A map index can be created for a top-level ordered map only. Nested and unordered map indexes are not supported.
