Method Detail

getSocketAtStandby

public CarouselSocket getSocketAtStandby()

Description copied from interface: Carousel

This methods returns the socket at standby position or null if there is no socket at standby position. If the carousel is rotating, it returns null.

Specified by:

getSocketAtStandby in interface Carousel

Overrides:

getSocketAtStandby in class CarouselModule

Returns:

the socket which is at standby position or null if there is no socket at standby position.

getPosition

public double getPosition()

Description copied from interface: Carousel

The carousel position measures the rotation angle of the carousel within the fixed part of the camera.

Specified by:

getPosition in interface Carousel

Overrides:

getPosition in class CarouselModule

Returns:

The position of the carousel in degrees. Its values is greater or equal to 0 and less than 360.
