Method Details

findOriginalResourceId

public Optional<ResourceId> findOriginalResourceId()

Description copied from interface: ResourceEntry

Finds the ResourceId associated with the node, or a result equivalent to Optional.empty() if no such resource id exists.

Returns:

an Optional<ResourceId> containing the ResourceId

getOriginalReversePathsImmutable

public Set<Path> getOriginalReversePathsImmutable()

Description copied from interface: ResourceEntry

Gets the internal immutable list of reverse links. Will always return an empty Set if no links exist.

Returns:

the reverse links, never null.

findOriginalResourceContents

public Optional<ResourceContents> findOriginalResourceContents()

Description copied from interface: ResourceEntry

Finds the original Resource contents.

Returns:

the Optional of ResourceContents

isOriginalReversePaths

public boolean isOriginalReversePaths()

Description copied from interface: ResourceEntry

Checks if the list of reverse links are the original set of reverse links.

Specified by:

isOriginalReversePaths in interface ResourceEntry

Overrides:

isOriginalReversePaths in class AbstractResourceEntry

Returns:

true if the links are original

close

public void close()

Description copied from interface: ResourceEntry

Closers this ResourceEntry releasing any underlying resources associated with the ResourceEntry.
