Method Detail

getEntityIDs

Collection<String> getEntityIDs()

Returns:

List of entity IDs for which this module produces data

getCurrentDescription

AbstractProcess getCurrentDescription(String entityID)

Retrieves the most current SensorML description of the given entity.

Parameters:

entityID - unique ID of the desired entity (e.g. sensor in a network)

Returns:

AbstractProcess SensorML description of the data producing entity or null if no description is available

getLastDescriptionUpdate

double getLastDescriptionUpdate(String entityID)

Used to check when SensorML description of the given entity was last updated. This is useful to avoid requesting the object when it hasn't changed.

Parameters:

entityID - unique ID of the desired entity (e.g. sensor in a network)

Returns:

Date/time of last description update as julian time (1970) or Long.MIN_VALUE if description was never updated.

getCurrentFeatureOfInterest

AbstractFeature getCurrentFeatureOfInterest(String entityID)

Retrieves the feature of interest for which the given entity is currently generating data.

Parameters:

entityID - unique ID of the desired entity (e.g. sensor in a network)

Returns:

Feature object

getFeaturesOfInterest

Collection<? extends AbstractFeature> getFeaturesOfInterest()

Returns:

Collection all features of interest for which this producer is generating data.

getFeaturesOfInterestIDs

Collection<String> getFeaturesOfInterestIDs()

Returns:

Collection of IDs of all features of interest for which this producer is generating data.
