Enum Index.OperationSource

java.lang.Object

java.lang.Enum<Index.OperationSource>

com.hazelcast.query.impl.Index.OperationSource

All Implemented Interfaces:

Serializable, Comparable<Index.OperationSource>

Enclosing interface:

Index

public static enum Index.OperationSource
extends Enum<Index.OperationSource>

Identifies an original source of an index operation.

Required for the index stats tracking to ignore index operations initiated internally by Hazelcast. We can't achieve the same behaviour on the pure stats level, e.g. by turning stats off during a partition migration, since global indexes and their stats are shared across partitions.

Enum Constant Summary

Enum Constant and Description
SYSTEM Indicates that an index operation was initiated internally by Hazelcast; for instance, as a result of a partition migration.
USER Indicates that an index operation was initiated by a user; for instance, as a result of a new map entry insertion.

Enum Constant Detail

USER

public static final Index.OperationSource USER

Indicates that an index operation was initiated by a user; for instance, as a result of a new map entry insertion.

SYSTEM

public static final Index.OperationSource SYSTEM

Indicates that an index operation was initiated internally by Hazelcast; for instance, as a result of a partition migration.

Method Detail

values

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

Returns:

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

valueOf

public static Index.OperationSource 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
