,java.lang.Comparable<InterpolationMode>
public enum InterpolationMode extends java.lang.Enum<InterpolationMode> implements Localized
Describes how values are interpolated/extrapolated in the history system.
Set on the tag level, it handles the situation when data is more sparse than the time frame requested.
The opposite isAggregationMode
, which handles the situation where data is too dense.

Discrete
public static final InterpolationMode Discrete
The last known value, no interpolation between value changes.
-
Analog
public static final InterpolationMode Analog
Same as Analog_Deadband, but the legacy value. For 7.3, we had to be able to distinguish between the old analog and the new version. Everything that was previously using this will now used the Compressed analog.
-
Analog_Deadband
public static final InterpolationMode Analog_Deadband
The last known value, interpolated between values during the transition period (1 scan class rate before new value).
-
Analog_Compressed
public static final InterpolationMode Analog_Compressed
Compressed with the SLIM algorithm. The trajectory of the value is tracked, and the deadband is used to form a corridor. A value is only logged when it goes outside the current corridor.

values
public static InterpolationMode[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (InterpolationMode c : InterpolationMode.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static InterpolationMode valueOf(java.lang.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:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
