Enum Constant Details

System

public static final Timestamp.TimestampSource System

Timestamp as reported by the system. This timestamp is captured when the system receives the signal value.

This timestamp is present on all systems and is guaranteed to be monotonic. However, this timestamp is the least accurate due to processing delays within the system.

CANivore

public static final Timestamp.TimestampSource CANivore

Timestamp as reported by the CANivore. This timestamp is captured when the CANivore receives the signal value.

The CANivore is synchronized to the system monotonic clock and benefits from reduced latency over the System timestamp.

On the native roboRIO CAN bus, this timestamp is equivalent to the System timestamp.

When used with CANivore, the only inaccuracy in this measurement is latency from CAN bus arbitration.

Device

public static final Timestamp.TimestampSource Device

This timestamp source is not currently implemented in this version of Phoenix Pro.

Timestamp as reported by the device. This timestamp is captured when the device transmits the signal value. Because it is timestamped in the device, it is the most accurate timestamp source.

This timestamp is synchronized to the CANivore clock, which is itself synchronized to the system monotonic clock. As a result, this timestamp source requires a CANivore.

It can be assumed there is no latency between this timestamp and when the data was taken.

Field Details

value

public final int value

Method Details

values

public static Timestamp.TimestampSource[] values()

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

Returns:

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

valueOf

public static Timestamp.TimestampSource valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name

NullPointerException - if the argument is null

valueOf

public static Timestamp.TimestampSource valueOf(int value)

Gets TimestampSource from specified value

Parameters:

value - Value of TimestampSouce

Returns:

TimestampSource of specified value
