Method Detail

getPid

String getPid()

Gets the pid of the object whose datastream is described by this record.

getId

String getId()

Gets the DSID for the datastream described by this record.

getControlGroup

String getControlGroup()

Get the control group for the datastream described by this record. This value, while significant in Fedora 3, is only present as an indicator of historic status, since storage management is handled through another mechanism in Fedora 4.

getState

String getState()

Gets the state for the datastream described by this record.

getVersionable

boolean getVersionable()

Gets the 'versionable' value for the datastream described by this record. This value does not imply anything about whether or how many versions of this datastream exists (there is always at least one) but instead was an indicator of whether an update to the described datastream in Fedora 3 would overwrite the current version or create a new one. In the context of fedora 4, this value is just to preserve the historical record.

getHistory

List<FedoraDatastreamVersionRecord> getHistory()

Returns a non-null, non-empty list of FedoraDatastreamVersionRecord objects representing the ordered history of this datastream from most recent to oldest.

getCurrentVersion

FedoraDatastreamVersionRecord getCurrentVersion()

Gets the most recent version of the datastream. This method is just a shortcut for getHistory().get(0).
