Constructor Detail

AbstractEntityAcceptingEntityImpl

protected AbstractEntityAcceptingEntityImpl(FileSystemImplementation fs,
                                            DirectoryImplementation parent,
                                            EntityDelegate delegate,
                                            Object[] lockIdentifiers)

Method Detail

hasFilters

public boolean hasFilters()

Description copied from interface: ViewCapable

Does this view have any filters?

Specified by:

hasFilters in interface ViewCapable<T extends EntityAcceptingEntityView<?>>

Returns:

false, always.

getFilter

public Filter<? super EntityView> getFilter()

Description copied from interface: ViewCapable

Get the filter that is used to create this view. If this is called on an entity, this method returns null.

Specified by:

getFilter in interface ViewCapable<T extends EntityAcceptingEntityView<?>>

Returns:

null, always.

dereferenceOrNull

public EntityImplementation dereferenceOrNull()

Description copied from interface: EntityAcceptingEntityView

Get the entity referenced by this entity. For a directory (view), this returns the directory (view). For a symbolic link (view), this returns (the same view of) the link target.

This method handles symbolic links in the symbolic link target correctly. For instance, if the symbolic link l1 has the target /d1/l2/f1 and the symbolic link l2 has the target ../d2, l1 will be dereferenced to the entity with the location /d2/f1 (given that d1 and d2 are directories).

Specified by:

dereferenceOrNull in interface EntityAcceptingEntityView<T extends EntityAcceptingEntityView<?>>

Returns:

The entity referenced by this entity

copyViewSettings

protected ViewCapable<?> copyViewSettings(ViewCapable<?> vc,
                                          EntityView ev)

Copy the view settings from the entity ev to the view capable entity ev.

Parameters:

vc - The view capable entity to create (possibly nested) views for

ev - The entity view whose view filters should be used.

Returns:

A view of vc with the same set of filters as ev.
