Enum MetadataPolicy

java.lang.Object

java.lang.Enum<MetadataPolicy>

com.hazelcast.config.MetadataPolicy

All Implemented Interfaces:

Serializable, Comparable<MetadataPolicy>

public enum MetadataPolicy
extends Enum<MetadataPolicy>

Hazelcast may process objects of supported types ahead of time to create additional metadata about them. This metadata then is used to make querying and indexing faster.

Enum Constant and Description
CREATE_ON_UPDATE Hazelcast processes supported objects at the time of creation and updates.
OFF Turns off metadata creation.

Enum Constant Detail

CREATE_ON_UPDATE

public static final MetadataPolicy CREATE_ON_UPDATE

Hazelcast processes supported objects at the time of creation and updates. This may increase put latency for the specific data structure that this option is configured with.

OFF

public static final MetadataPolicy OFF

Turns off metadata creation.

Method Detail

values

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

Returns:

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

valueOf

public static MetadataPolicy 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

getId

public int getId()

Returns enumeration id of this policy. We use id field instead of Enum.ordinal() because this value is used in client protocol. The ids for the known policies must not be changed.

Returns:

id

getById

public static MetadataPolicy getById(int id)

Returns the MetadataPolicy for the given ID.

Returns:

the MetadataPolicy found or null if not found
