Member Function Documentation

SignalId Timeline::createSignal ( Id id, string xlinkHref, MimeClass mimeClass, MimeType mimeType, Encoding encoding, Unit unit, string track ) throw (AGException)

Create a new signal and add it to the timeline. Parameters: id   might be TimelineId or SignalId. If id is a TimelineId, an SignalId will be assigned to new Signal. If id is a SignalId, it will try the given id first, if it's taken, assign a new SignalId. Returns: SignalId of the new signal. Exceptions: AGException   IF (the id given is invalid)

void Timeline::deleteFeature ( FeatureName featureName )

Delete the specified feature in the metadata.

void Timeline::deleteSignal ( Signal * signal )

Remove a signal from the timeline.

bool Timeline::existsFeature ( FeatureName featureName )

Test if a feature exists in the metadata.

string Timeline::getFeature ( FeatureName featureName )

Get the value of the specified feature in the metadata.

StringSet Timeline::getFeatureNames ( )

Get feature names in the metadata Returns: string set which contains all the feature names

Features Timeline::getFeatures ( )

Get all the features in a single string. returns all features in a single string in Dublin Core Structured Values DCSV (Cox & Iannella) format. For example, "name=Stone Philips;phone=(215)555-8888;age=40" Note: see http://dublincore.org/documents/2000/07/28/dcmi-dcsv/ for details about DCSV format.

const Id Timeline::getId ( ) const [inline]

Get the id of the timeline.

IdSet Timeline::getSignals ( ) const

Get signal Ids.

void Timeline::setFeature ( FeatureName featureName, FeatureValue featureValue )

Set the value of a feature in the metadata.

void Timeline::setFeatures ( Features features )

Set multiple features in a single string. Set multiple features in a single string in Dublin Core Structured Values DCSV (Cox & Iannella) format. For example, "name=Stone Philips;phone=(215)555-8888;age=40" Note: see http://dublincore.org/documents/2000/07/28/dcmi-dcsv/ for details about DCSV format.

list< string > Timeline::storeSQLs ( AGSetId id )

Create list of SQLs used to save the timeline to the DB server.

string Timeline::toString ( )

Dump the timeline in AIF format.

void Timeline::unsetFeatures ( )

Unset all features in the metadata Set all the features to empty string.
