AbstractProxyFactory

protected AbstractProxyFactory(DatabaseCluster<Z,D> cluster,
                    Map<D,T> map,
                    Class<E> exceptionClass)

Constructs a new proxy to a set of objects

Parameters:

map - a map of database to sql object.

exceptionClass - the class for exceptions thrown by this object

Method Detail

getDatabaseCluster

public DatabaseCluster<Z,D> getDatabaseCluster()

Specified by:

getDatabaseCluster in interface ProxyFactory<Z,D extends Database<Z>,T,E extends Exception>

remove

protected T remove(D database)

entries

public Set<Map.Entry<D,T>> entries()

Specified by:

entries in interface ProxyFactory<Z,D extends Database<Z>,T,E extends Exception>

children

protected Iterable<ChildProxyFactory<Z,D,T,E,?,? extends Exception>> children()

addChild

public void addChild(ChildProxyFactory<Z,D,T,E,?,? extends Exception> child)

Specified by:

addChild in interface ProxyFactory<Z,D extends Database<Z>,T,E extends Exception>

removeChild

public void removeChild(ChildProxyFactory<Z,D,T,E,?,? extends Exception> child)

Specified by:

removeChild in interface ProxyFactory<Z,D extends Database<Z>,T,E extends Exception>

removeChildren

public final void removeChildren()

Specified by:

removeChildren in interface ProxyFactory<Z,D extends Database<Z>,T,E extends Exception>

get

public T get(D database)

Returns the underlying SQL object for the specified database. If the sql object does not exist (this might be the case if the database was newly activated), it will be created from the stored operation. Any recorded operations are also executed. If the object could not be created, or if any of the executed operations failed, then the specified database is deactivated.

Specified by:

get in interface ProxyFactory<Z,D extends Database<Z>,T,E extends Exception>

Parameters:

database - a database descriptor.

Returns:

an underlying SQL object

create

protected abstract T create(D database)
                     throws TE extends Exception

Throws:

TE extends Exception

record

public void record(Invoker<Z,D,T,?,E> invoker)

Specified by:

record in interface ProxyFactory<Z,D extends Database<Z>,T,E extends Exception>

replay

public void replay(D database,
          T object)
            throws E extends Exception

Specified by:

replay in interface ProxyFactory<Z,D extends Database<Z>,T,E extends Exception>

Throws:

E

E extends Exception

getExceptionFactory

public final ExceptionFactory<E> getExceptionFactory()

Specified by:

getExceptionFactory in interface ProxyFactory<Z,D extends Database<Z>,T,E extends Exception>
