Class DataPersistenceConfig

java.lang.Object

com.hazelcast.config.DataPersistenceConfig

All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable

public class DataPersistenceConfig
extends Object
implements IdentifiedDataSerializable

Configures the Persistence per Hazelcast data structure.

Note: If either, but not both, data-persistence (DataPersistenceConfig) or hot-restart (HotRestartConfig) is enabled, Hazelcast will use the configuration of the enabled element. If both are enabled, Hazelcast will use the data-persistence (DataPersistenceConfig) configuration. hot-restart element (and thus HotRestartConfig) will be removed in a future release.

Method Detail

isEnabled

public boolean isEnabled()

Returns whether persistence enabled on related data structure.

Returns:

true if persistence enabled, false otherwise

setEnabled

public DataPersistenceConfig setEnabled(boolean enabled)

Sets whether hot restart is enabled on related data structure.

Returns:

DataPersistenceConfig

isFsync

public boolean isFsync()

Returns whether disk write should be followed by an fsync() system call.

Returns:

true if fsync is be called after disk write, false otherwise

setFsync

public DataPersistenceConfig setFsync(boolean fsync)

Sets whether disk write should be followed by an fsync() system call.

Parameters:

fsync - fsync

Returns:

this DataPersistenceConfig

toString

public String toString()

Overrides:

toString in class Object

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Returns:

factory ID

getClassId

public int getClassId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. It should be unique per DataSerializableFactory.

Specified by:

getClassId in interface IdentifiedDataSerializable

Returns:

type ID

writeData

public void writeData(ObjectDataOutput out)
               throws IOException

Description copied from interface: DataSerializable

Writes object fields to output stream

Specified by:

writeData in interface DataSerializable

Parameters:

out - output

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

readData

public void readData(ObjectDataInput in)
              throws IOException

Description copied from interface: DataSerializable

Reads fields from the input stream

Specified by:

readData in interface DataSerializable

Parameters:

in - input

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the input stream has been closed.

equals

public final boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public final int hashCode()

Overrides:

hashCode in class Object
