ServiceComponentImpl

public ServiceComponentImpl(String name,
                    String language,
                    StreamType streamType,
                    Service service,
                    ProgramEvent program,
                    ServiceInformationType siType,
                    boolean autorun,
                    Date updatedTime)

Method Detail

getName

public String getName()

Returns a name associated with this component. The Component Descriptor (DVB) or Component Name Descriptor (ATSC) may be used if present. A generic name (e.g. video, first audio, etc.) may be used otherwise.

Specified by:

getName in interface ServiceComponent

Returns:

A string representing the component name. The string is empty if no name can be associated with this component.

getAssociatedLanguage

public String getAssociatedLanguage()

Called to identified the language used for the elementary stream.

Specified by:

getAssociatedLanguage in interface ServiceComponent

Returns:

A string representing a language code defining the language associated with this component. It contains a three-character code as specified by ISO 639.2/B. Empty string is returned when there is no language associated with this component.

getStreamType

public StreamType getStreamType()

Provides the stream type of this component. (E.g. "video", "audio", etc.)

Specified by:

getStreamType in interface ServiceComponent

Returns:

Stream type of this component.

getService

public Service getService()

Provides the Service to which this ServiceComponentImpl belongs. The result may be null if the Service cannot be determined.

Specified by:

getService in interface ServiceComponent

Returns:

The Service to which this ServiceComponentImpl belongs.

getLocator

public Locator getLocator()

Gets the complete Locator of this SI Element. Each SI Element (such as BroadcastService, ProgramEvent, etc.) in the MPEG-2 domain is identified by a Locator. This identification is encapsulated by the Locator object which may use a URL format, specific MPEG numbers, such as network ID, etc., or other mechanisms.

Specified by:

getLocator in interface SIElement

Returns:

Locator representing this SI Element

getUpdateTime

public Date getUpdateTime()

Returns the time when this object was last updated from data in the broadcast.

Specified by:

getUpdateTime in interface SIRetrievable

Returns:

The date of the last update in UTC format, or null if unknown.

getServiceInformationType

public ServiceInformationType getServiceInformationType()

Reports the service information format of this object.

Specified by:

getServiceInformationType in interface SIElement

Returns:

The service information format.

getProgramEvent

public ProgramEvent getProgramEvent()

Provides the ProgramEvent to which this ServiceComponentImpl belongs. The result may be null if the ProgramEvent cannot be determined.

Returns:

The ProgramEvent to which this ServiceComponentImpl belongs or null if this ServiceComponent does not belong to a ProgramEvent.

isAutoRun

public boolean isAutoRun()

setSelectionFailedReason

public void setSelectionFailedReason(int reason)

getSelectionFailedReason

public int getSelectionFailedReason()
