Enum Class ClusterEventType

java.lang.Object

java.lang.Enum<ClusterEventType>

org.gcube.informationsystem.resourceregistry.cluster.ClusterEventType

All Implemented Interfaces:

Serializable, Comparable<ClusterEventType>, Constable

public enum ClusterEventType
extends Enum<ClusterEventType>

The kinds of event broadcast across service instances over the ClusterEventBus.

Adding a new kind here is the whole cost of adding a new cross-instance signal: the bus itself, its two transport channels, and its de-duplication are shared by every kind. In particular, a new kind does not cost an additional permanently-reserved OrientDB session, which is what a per-concern Live Query subscription would cost.

Enum Constant Summary

Enum Constants

Enum Constant	Description
POOL_INVALIDATION	An ODatabasePool must be discarded because the permission state it authenticated with is now stale.
SCHEMA_CHANGE	The Type schema changed (a Type was created, updated, or deleted), so every projection derived from it — the Redis type cache, the model knowledge, the generated documentation, the schema loaded by the connection pools — is now out of date.

Method Summary

Modifier and Type	Method	Description
static ClusterEventType	valueOf(String name)	Returns the enum constant of this class with the specified name.
static ClusterEventType[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

POOL_INVALIDATION

public static final ClusterEventType POOL_INVALIDATION

An ODatabasePool must be discarded because the permission state it authenticated with is now stale. Payload: the affected Context UUID, as a string.

SCHEMA_CHANGE

public static final ClusterEventType SCHEMA_CHANGE

The Type schema changed (a Type was created, updated, or deleted), so every projection derived from it — the Redis type cache, the model knowledge, the generated documentation, the schema loaded by the connection pools — is now out of date. Payload: the schema version the emitting instance had just written, as a string.

Method Details

values

public static ClusterEventType[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static ClusterEventType valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
