PredicateRTIndicator

public PredicateRTIndicator(@NonNull
 @NonNull RTIndicator indicator,
 @NonNull
 @NonNull Predicate<Double> predicate)

Method Details

update

public final double update(double newValue)

Updates the decorated indicator and applies the predicate filter. Only accepts the new value if the predicate passes; otherwise retains the last accepted value. Useful for filtering out values outside a desired range.

Specified by:

update in interface RTIndicator

Overrides:

update in class AbstractRTIndicator

Parameters:

newValue - the new input value

Returns:

the new value if predicate passes, or the previous accepted value

equal

public static PredicateRTIndicator equal(RTIndicator indicator,
 @NonNull
 @NonNull Number coefficient)

notEqual

public static PredicateRTIndicator notEqual(RTIndicator indicator,
 @NonNull
 @NonNull Number coefficient)

lessThan

public static PredicateRTIndicator lessThan(RTIndicator indicator,
 @NonNull
 @NonNull Number coefficient)

lessOrEqual

public static PredicateRTIndicator lessOrEqual(RTIndicator indicator,
 @NonNull
 @NonNull Number coefficient)

greatThan

public static PredicateRTIndicator greatThan(RTIndicator indicator,
 @NonNull
 @NonNull Number coefficient)

greatOrEqual

public static PredicateRTIndicator greatOrEqual(RTIndicator indicator,
 @NonNull
