Enum SegmentationPolicy

java.lang.Object

java.lang.Enum<SegmentationPolicy>

org.apache.ignite.plugin.segmentation.SegmentationPolicy

All Implemented Interfaces:

Serializable, Comparable<SegmentationPolicy>

public enum SegmentationPolicy
extends Enum<SegmentationPolicy>

Policy that defines how node will react on topology segmentation. Note that default segmentation policy is defined by IgniteConfiguration.DFLT_SEG_PLC property.

Enum Constant Summary

Enum Constants

Enum Constant and Description
NOOP When segmentation policy is NOOP, all listeners will receive EventType.EVT_NODE_SEGMENTED event and it is up to user to implement logic to handle this event.
RESTART_JVM When segmentation policy is RESTART_JVM, all listeners will receive EventType.EVT_NODE_SEGMENTED event and then JVM will be restarted.
STOP When segmentation policy is STOP, all listeners will receive EventType.EVT_NODE_SEGMENTED event and then particular grid node will be stopped via call to Ignition.stop(String, boolean).
USE_FAILURE_HANDLER Use configured failure handler.

Method Summary

Modifier and Type	Method and Description
static @Nullable SegmentationPolicy	fromOrdinal(int ord) Efficiently gets enumerated value from its ordinal.
static SegmentationPolicy	valueOf(String name) Returns the enum constant of this type with the specified name.
static SegmentationPolicy[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

RESTART_JVM

public static final SegmentationPolicy RESTART_JVM

When segmentation policy is RESTART_JVM, all listeners will receive EventType.EVT_NODE_SEGMENTED event and then JVM will be restarted. Note, that this will work only if Ignite is started with CommandLineStartup via standard ignite.{sh|bat} shell script.

STOP

public static final SegmentationPolicy STOP

When segmentation policy is STOP, all listeners will receive EventType.EVT_NODE_SEGMENTED event and then particular grid node will be stopped via call to Ignition.stop(String, boolean).

NOOP

public static final SegmentationPolicy NOOP

When segmentation policy is NOOP, all listeners will receive EventType.EVT_NODE_SEGMENTED event and it is up to user to implement logic to handle this event.

USE_FAILURE_HANDLER

public static final SegmentationPolicy USE_FAILURE_HANDLER

Use configured failure handler. It is default segmentation policy.

Method Detail

values

public static SegmentationPolicy[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (SegmentationPolicy c : SegmentationPolicy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SegmentationPolicy valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

fromOrdinal

@Nullable
public static @Nullable SegmentationPolicy fromOrdinal(int ord)

Efficiently gets enumerated value from its ordinal.

Parameters:

ord - Ordinal value.

Returns:

Enumerated value or null if ordinal out of range.
