DesiredRateExpressionImpl

public DesiredRateExpressionImpl(SourceRateExpression<?> expression,
                                 Function<R> collector,
                                 java.lang.String defaultName)

Creates a new expression at the desired rate. Use this constructor when making an DesiredRateExpression out of a collector and a SourceRateExpression.

Parameters:

expression - the original source rate expression

collector - the collector for the original source

defaultName - the display name of the expression

DesiredRateExpressionImpl

public DesiredRateExpressionImpl(DesiredRateExpressionList<?> childExpressions,
                                 Function<R> function,

Creates a new aggregated expression. Use this constructor when making a DesiredRateExpression that is a function of a number of DesiredRateExpressions.

Parameters:

childExpressions - expressions for the arguments of the function

function - the function that calculates the value of the new expression

defaultName - the display name of the expression
