Enum Constant Details

kUnknown

public static final TimestampSource kUnknown

unknown.

kFrameDequeue

public static final TimestampSource kFrameDequeue

wpi::Now when the new frame was dequeued by CSCore. Does not account for camera exposure time or V4L latency.

kV4LEOF

public static final TimestampSource kV4LEOF

End of Frame. Same as V4L2_BUF_FLAG_TSTAMP_SRC_EOF, translated into wpi::Now's timebase.

kV4LSOE

public static final TimestampSource kV4LSOE

Start of Exposure. Same as V4L2_BUF_FLAG_TSTAMP_SRC_SOE, translated into wpi::Now's timebase.

Method Details

values

public static TimestampSource[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static TimestampSource valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

getValue

public int getValue()

Gets the integer value of the pixel format.

Returns:

Integer value

getFromInt

public static TimestampSource getFromInt(int timestampSource)

Gets a TimestampSource enum value from its integer value.

Parameters:

timestampSource - integer value

Returns:

Enum value
