Enum ConflictResolverFactory

java.lang.Object

java.lang.Enum<ConflictResolverFactory>

com.basho.riak.client.api.cap.ConflictResolverFactory

All Implemented Interfaces:

Serializable, Comparable<ConflictResolverFactory>

public enum ConflictResolverFactory
extends Enum<ConflictResolverFactory>

Simple factory for ConflictResolver objects.

When you have multiple writers there may be multiple versions of the same object stored in Riak. When fetching all of these will be returned and you will need to resolve the conflict.

To facilitate this, you can store an instance of the ConflictResolver in this factory for a class. It will then be used by the FetchValue.Response to resolve a set a of siblings to a single object.

Method Detail

values

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

Returns:

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

valueOf

public static ConflictResolverFactory 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

getInstance

public static ConflictResolverFactory getInstance()

Returns the instance of the ConflictResolverFactory.

Returns:

The ConflictResolverFactory

getConflictResolver

public <T> ConflictResolver<T> getConflictResolver(Class<T> clazz)

getConflictResolver

public <T> ConflictResolver<T> getConflictResolver(com.fasterxml.jackson.core.type.TypeReference<T> typeReference)

registerConflictResolver

public <T> void registerConflictResolver(Class<T> clazz,
                                         ConflictResolver<T> resolver)

The instance provided will be used to resolve siblings for the given type.

Type Parameters:

T - The type being resolved

Parameters:

clazz - the class of the type being resolved

resolver - an instance of a class implementing ConflictResolver.

registerConflictResolver

public <T> void registerConflictResolver(com.fasterxml.jackson.core.type.TypeReference<T> typeReference,
                                         ConflictResolver<T> resolver)

unregisterConflictResolver

public <T> void unregisterConflictResolver(Class<T> clazz)

Unregister a ConflictResolver.

Type Parameters:

T - The type being Resolved

Parameters:

clazz - the class of the type being resolved.

unregisterConflictResolver

public <T> void unregisterConflictResolver(com.fasterxml.jackson.core.type.TypeReference<T> typeReference)
