Class CachelessIndicator<T>

java.lang.Object

trade.invision.indicators.indicators.Indicator<T>

trade.invision.indicators.indicators.CachelessIndicator<T>

Type Parameters:

T - the Indicator type

Direct Known Subclasses:

BarEnd, BarStart, Close, ConstantArray, ConstantValue, CurrentIndex, High, IsIndexStable, Low, NumDatapointInstant, NumDatapointValue, Open, PreviousValue, Replacement, SeriesReference, TradeCount, Volume

public abstract class CachelessIndicator<T>
extends Indicator<T>

CachelessIndicator is an abstract Indicator class that permanently disables caching. This is useful for Indicator implementations that derive their calculated values from existing data without any modifications.

Method Details

caching

public <A extends Indicator<T>> A caching()

Description copied from class: Indicator

Permanently enables caching of this Indicator's calculated values in order to optimize Indicator.getValue(long) for non-ending indices. The cache should be enabled when consumers of this Indicator use the calculated values of non-ending indices, as opposed to only using the calculated value of the end index (e.g. Series.getEndIndex()). The cache size is equal to Indicator.getSeries() Series.getMaximumLength().

Overrides:

caching in class Indicator<T>

Returns:

this Indicator, for method chaining
