Enum GridSegmentationPolicy

java.lang.Object

java.lang.Enum<GridSegmentationPolicy>

org.apache.ignite.plugin.segmentation.GridSegmentationPolicy

All Implemented Interfaces:

Serializable, Comparable<GridSegmentationPolicy>

public enum GridSegmentationPolicy
extends Enum<GridSegmentationPolicy>

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).

Enum Constant Detail

RESTART_JVM

public static final GridSegmentationPolicy 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 GridSegmentationPolicy 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 GridSegmentationPolicy 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.

Method Detail

values

public static GridSegmentationPolicy[] 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 (GridSegmentationPolicy c : GridSegmentationPolicy.values())
    System.out.println(c);

Returns:

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

valueOf

public static GridSegmentationPolicy 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
