Package dev.enola.data

Class RepositoryBuilder<T>

java.lang.Object

dev.enola.data.RepositoryBuilder<T>

All Implemented Interfaces:

Builder<Repository<T>>, Provider<String,T>, ProviderFromIRI<T>, Repository<T>, RepositoryRW<T>, Store<T>

Direct Known Subclasses:

DatatypeRepositoryBuilder, NamespaceRepositoryBuilder, ThingMemoryRepositoryROBuilder

public abstract class RepositoryBuilder<T>
extends Object
implements RepositoryRW<T>, Builder<Repository<T>>

RepositoryBuilder builds immutable Repository instances.

This Builder class itself is NOT thread-safe. The Repository returned by its build() however is thread-safe (simply because it's immutable). Use MemoryRepositoryRW for a thread-safe Store.

Method Details

map

protected Map<String,T> map()

store

public RepositoryBuilder<T> store(T item)

Description copied from interface: Store

Store a T.

If this store already has this T, then it's replaced (entirely, not "merged").

Specified by:

store in interface Store<T>

storeAll

public RepositoryBuilder<T> storeAll(Iterable<T> items)

Description copied from interface: Store

Store multiple Ts; see Store.store(Object).

Specified by:

storeAll in interface Store<T>

build

public Repository<T> build()

Specified by:

build in interface Builder<T>

buildMap

protected ImmutableSortedMap<String,T> buildMap()

require

protected <O> O require(O what,
 String identification)

getIRI

protected abstract String getIRI(T value)

list

public Iterable<T> list()

Description copied from interface: Repository

list() returns Ts directly (not just the IRIs, like Repository.listIRI()).

This default implementation here just combines Repository.listIRI() and ProviderFromIRI.get(String). Your subclass may be able to provide a more efficient and more "direct" implementation?

Specified by:

list in interface Repository<T>

listIRI

public Iterable<String> listIRI()

Specified by:

listIRI in interface Repository<T>

get

public T get(String iri)

Description copied from interface: Provider

Get.

Specified by:

get in interface Provider<String,T>

Specified by:

get in interface ProviderFromIRI<T>

Parameters:

iri - Key, never null

Returns:

value, or null if there is no Value for the given key

trigger

protected void trigger(T existing,
 T updated)
