Interface PortControl

All Superinterfaces:

Control

public interface PortControl

extends Control

The PortControl interface represents a control to access the input or output ports of a device. A device in this case could be an capture device (CaptureDevice) or a renderer (Renderer). Methods are provided to find out what ports the device includes, to find out which ports are currently turned on, and to turn a port on or off.

Field Summary

static int	COMPACT_DISC Specifies a compact disc port.
static int	COMPOSITE_VIDEO Specifies a composite video port.
static int	COMPOSITE_VIDEO_2 Specifies a second composite video port.
static int	HEADPHONE Specifies a headphone port.
static int	LINE_IN Specifies a line in port.
static int	LINE_OUT Specifies a line out port.
static int	MICROPHONE Specifies a microphone port.
static int	SPEAKER Specifies a speaker port.
static int	SVIDEO Specifies a S-Video port.
static int	TV_TUNER Specifies a TV-Tuner input port.

Method Summary

int	getPorts() Obtains the set of ports currently enabled.
int	getSupportedPorts() Obtains the set of ports supported by the device that is controlled by this PortControl object.
int	setPorts(int ports) Set the enabled ports.

Method Detail

setPorts

public int setPorts(int ports)

Set the enabled ports. The enabled ports are given as the logical "OR" of the bit mask value of the desired ports.

For example, to enable microphone and line in, use setPorts(MICROPHONE | LINE_IN).

Parameters:

ports - the logical "OR" of the bit mask value of the ports.

Returns:

the integer bit mask of the all the ports that are enabled.

getPorts

public int getPorts()

Obtains the set of ports currently enabled.

Returns:

the set of enabled ports. The value returned is the logical "OR" of the bit mask value of the enabled ports.

getSupportedPorts

public int getSupportedPorts()

Obtains the set of ports supported by the device that is controlled by this PortControl object.

Returns:

the set of supported ports. The value returned is the logical "OR" of the bit mask value of the enabled ports.
