Field Summary

static int	LOCAL The video origin of a VideoEvent which is local to the executing client such as a local video capture device.
static int	REMOTE The video origin of a VideoEvent which is remote to the executing client such as a video being remotely streamed from a CallPeer.
static int	VIDEO_ADDED The type of a VideoEvent which notifies about a specific visual Component depicting video being made available by the firing provider.
static int	VIDEO_REMOVED The type of a VideoEvent which notifies about a specific visual Component depicting video no longer being made available by the firing provider.

source

Constructor Summary

VideoEvent(Object source, int type, Component visualComponent, int origin)
Initializes a new VideoEvent which is to notify about a specific change in the availability of a specific visual Component depicting video and being provided by a specific source.

Method Summary

void	consume() Consumes this event and, more specifically, marks the Component it describes as owned, referenced in order to let other potential consumers know about its current ownership status (which is important because Components belong to a single Container at a time).
int	getOrigin() Gets the origin of the video this VideoEvent notifies about which is one of LOCAL and REMOTE.
int	getType() Gets the type of availability change this VideoEvent notifies about which is one of VIDEO_ADDED and VIDEO_REMOVED.
Component	getVisualComponent() Gets the visual Component depicting video which had its availability changed and which this VideoEvent notifies about.
boolean	isConsumed() Determines whether this event and, more specifically, the visual Component it describes have been consumed and should be considered owned, referenced (which is important because Components belong to a single Container at a time).

VideoEvent

public VideoEvent(Object source,
                  int type,
                  Component visualComponent,
                  int origin)

Initializes a new VideoEvent which is to notify about a specific change in the availability of a specific visual Component depicting video and being provided by a specific source.

Parameters:

source - the source of the new VideoEvent and the provider of the visual Component depicting video

type - the type of the availability change which has caused the new VideoEvent to be fired

visualComponent - the visual Component depicting video which had its availability in the source provider changed

origin - the origin of the video the new VideoEvent is to notify about

Method Detail

consume

public void consume()

Consumes this event and, more specifically, marks the Component it describes as owned, referenced in order to let other potential consumers know about its current ownership status (which is important because Components belong to a single Container at a time).

getOrigin

public int getOrigin()

Gets the origin of the video this VideoEvent notifies about which is one of LOCAL and REMOTE.

Returns:

one of LOCAL and REMOTE which specifies the origin of the video this VideoEvent notifies about

getType

public int getType()

Gets the type of availability change this VideoEvent notifies about which is one of VIDEO_ADDED and VIDEO_REMOVED.

Returns:

one of VIDEO_ADDED and VIDEO_REMOVED which describes the type of availability change this VideoEvent notifies about

getVisualComponent

public Component getVisualComponent()

Gets the visual Component depicting video which had its availability changed and which this VideoEvent notifies about.

Returns:

the visual Component depicting video which had its availability changed and which this VideoEvent notifies about

isConsumed

public boolean isConsumed()

Determines whether this event and, more specifically, the visual Component it describes have been consumed and should be considered owned, referenced (which is important because Components belong to a single Container at a time).

Returns:

true if this event and, more specifically, the visual Component it describes have been consumed and should be considered owned, referenced (which is important because Components belong to a single Container at a time); otherwise, false
