FunctionIndicator<T extends IndicatorResult> class

A CachedIndicator that computes its values by calling an externally supplied bulk math function, instead of an acme_indicators calculation.

Constructors

FunctionIndicator(Indicator<T> _source, List<double> _compute(List<IndicatorOHLC> bars, List<double> values))

Initializes.

Properties

entries → List<IndicatorOHLC>

The entries of the input

no setter, inherited

hashCode → int

The hash code for this object.

no setter, inherited

input → IndicatorDataInput

IndicatorDataInput to calculate indicator values on.

final, inherited

lastResultIndex ↔ int

Index of the last result that is calculated.

getter/setter pair, inherited

results → List<T>

List of cached result.

final, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

applyBulkValues(List<double> values) → List<T>

Writes a bulk-computed values list into results and marks every entry calculated. Returns results, matching calculateValues's contract.

inherited

calculate(int index) → T

Calculates the value of this indicator for the given index without caching it.

calculateValues() → List<T>

Calculates indicator's result for all entries and caches them.

copyValuesFrom(covariant CachedIndicator<T> other) → void

Copies the result of other as its own.

inherited

createResult({required double quote, required int index}) → T

Creates a IndicatorResult entry.

inherited

getValue(int index) → T

Value of the indicator for the given index.

inherited

invalidate(int index) → void

Invalidates a calculated indicator value for index

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

refreshValueFor(int index) → T

Recalculates indicator's value for the give index and caches it.

inherited

seriesFrom(Indicator<T> indicator) → List<double>

Primes indicator (if it bulk-caches its own values) and returns its per-bar quote series across entries.

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
