All Implemented Interfaces:

Serializable, Comparable<RegistryStrategy>

public enum RegistryStrategy
extends Enum<RegistryStrategy>

Enum Constant Detail

DATABASE

public static final RegistryStrategy DATABASE

Use the database to synchronize between several parallel instances. Slow but requires less memory.

CACHE

public static final RegistryStrategy CACHE

Use a synchronized replicated infinispan cache to synchronize between parallel instances. Faster but requires more memory.

LOCAL

public static final RegistryStrategy LOCAL

Use a local in-memory hash map to synchronize between parallel instances. Does not synchronize across machines in a cluster

Method Detail

values

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

Returns:

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

valueOf

public static RegistryStrategy 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
