Constructor and Description
SensorDataEvent(long timeStamp, ISensorDataInterface dataInterface, net.opengis.swe.v20.DataBlock... records) Constructs an event for data produced by an isolated sensor. The sensor ID is obtained from the sensor description of the parent sensor module.
SensorDataEvent(long timeStamp, String sensorID, IStreamingDataInterface dataInterface, net.opengis.swe.v20.DataBlock... records) Constructs an event for data produced by the specified sensor. This flavor is used to identify a particular sensor within a network.

Method Summary

Methods

Modifier and Type	Method and Description
String	getSensorID() Gets the unique ID of the sensor related to this event. For sensor networks, it can be either the ID of the network as a whole (if the attached data includes records generated by all or several members of the network) or the ID of one of the sensor in the network (if the attached data has been generated by a single sensor).
ISensorDataInterface	getSource() Gets the source of the event as an object reference.

Constructor Detail

SensorDataEvent

public SensorDataEvent(long timeStamp,
               ISensorDataInterface dataInterface,
               net.opengis.swe.v20.DataBlock... records)

Constructs an event for data produced by an isolated sensor.
The sensor ID is obtained from the sensor description of the parent sensor module.

Parameters:

timeStamp - time of event generation (unix time in milliseconds, base 1970)

dataInterface - sensor output interface that produced the associated data

records - arrays of records that triggered this notification

SensorDataEvent

public SensorDataEvent(long timeStamp,
               String sensorID,
               IStreamingDataInterface dataInterface,
               net.opengis.swe.v20.DataBlock... records)

Constructs an event for data produced by the specified sensor.
This flavor is used to identify a particular sensor within a network.

Parameters:

timeStamp - time of event generation (unix time in milliseconds, base 1970)

sensorID - Unique ID of the sensor that produced the data

dataInterface - stream interface that generated the associated data

records - arrays of records that triggered this notification

Method Detail

getSensorID

public String getSensorID()

Gets the unique ID of the sensor related to this event.
For sensor networks, it can be either the ID of the network as a whole (if the attached data includes records generated by all or several members of the network) or the ID of one of the sensor in the network (if the attached data has been generated by a single sensor).

Returns:

the ID of the sensor that this event refers to

getSource

public ISensorDataInterface getSource()

Description copied from class: Event

Gets the source of the event as an object reference.

Overrides:

getSource in class DataEvent

Returns:

Source object that generated this event
