Constructor Details

DistanceRTIndicator

public DistanceRTIndicator(@NonNull
 @NonNull RTIndicator indicator,
 @NonNull
 @NonNull RTIndicator baseIndicator)

Method Details

update

public double update(double newValue)

Computes the fractional distance between two indicators: (indicator - base) / base. Both indicators receive the same input value. Returns 0 when the base is zero to avoid division by zero.

Specified by:

update in interface RTIndicator

Overrides:

update in class AbstractRTIndicator

Parameters:

newValue - the input value forwarded to both indicators

Returns:

the fractional distance between the two indicator values
