public interface DirectoryViewImplementation
extends EntityAcceptingEntityViewImplementation<DirectoryView>, DirectoryView

This is the interface for a DirectoryView implementation. It contains methods that are only used by file system implementations; not by file system clients. A DirectoryView object can always be cast to a DirectoryViewImplementation object.

The methods in this interface should only be used by file system and capability implementations.

Method Detail

copyFrom

Set<EntityView> copyFrom(EntityImplementation source,
                         String targetName,
                         boolean preserveAttrs,
                         List<EntityAttributeSetter> asl,
                         EntityLock[] setupLocks)
                         throws EntityFoundException

Copy the contents from the EntityAdapter to one or more new entities in the viewed directory. The directory implementation of this method delegates to DirectoryDelegate.copyFromEntity(EntityImplementation, String, boolean, List, EntityLock[]) after validating the target directory.

Parameters:

source - The entity to copy from.

targetName - The name of the new entity.

preserveAttrs - Should entity attributes be copied to the target entity?

asl - A list of EntityAttributeSetter objects that are run just after the target entity has been created, before the setupLocks are released. May be null. This may only be non- null if preserveAttrs is true.

setupLocks - Locks required for setting up the target entity. The locks are released when the target entity has been created. It is the responsibility of this method to unlock the lock (once), even in case of errors.

Returns:

The created entities. ViewCapable entities inherit the filter instances from this directory view.

Throws:

EntityFoundException
