Record Class Criterion

java.lang.Object

java.lang.Record

io.nosqlbench.scenarios.simframe.capture.Criterion

Record Components:

name - name of the factor

evaltype - Whether to compute the basis value as a deltaV/deltaT, a raw value, or a functional remix of the other values.

remix - A remix function, required for EvalType.remix

supplier - A value supplier, required for EvalType.direct and EvalType.deltaT

weight - A weight which affects how the basis value is applied as a factor to composite value. Set this to NaN to nullify effects.

frameStartCallback - A runnable which can be used to do preparatory work at the start of sampling a simulation frame

public record Criterion(String name, EvalType evaltype, ToDoubleFunction<BasisValues> remix, DoubleSupplier supplier, double weight, Runnable frameStartCallback)
extends Record

A criterion is a single component factor of a value for a black-box testing samples.

Criterion

public Criterion(String name,
 EvalType evaltype,
 ToDoubleFunction<BasisValues> remix,
 DoubleSupplier supplier,
 double weight,
 Runnable frameStartCallback)

Creates an instance of a Criterion record class.

Parameters:

name - the value for the name record component

evaltype - the value for the evaltype record component

remix - the value for the remix record component

supplier - the value for the supplier record component

weight - the value for the weight record component

frameStartCallback - the value for the frameStartCallback record component

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

name

public String name()

Returns the value of the name record component.

Returns:

the value of the name record component

evaltype

public EvalType evaltype()

Returns the value of the evaltype record component.

Returns:

the value of the evaltype record component

remix

public ToDoubleFunction<BasisValues> remix()

Returns the value of the remix record component.

Returns:

the value of the remix record component

supplier

public DoubleSupplier supplier()

Returns the value of the supplier record component.

Returns:

the value of the supplier record component

weight

public double weight()

Returns the value of the weight record component.

Returns:

the value of the weight record component

frameStartCallback

public Runnable frameStartCallback()

Returns the value of the frameStartCallback record component.

Returns:

the value of the frameStartCallback record component
