com.eqixiac.equinix.design.spi.SolveProblem

Record Components:

context - the facts of this run

candidates - the metros to form portfolios from

objectives - what to measure; each id appears once

constraints - the hard limits

weights - relative weight per objective id (need not sum to 1; missing ids weigh 0)

minMetros - fewest metros in a portfolio, at least 1

maxMetros - most metros in a portfolio, at least minMetros

public record SolveProblem(DesignContext context, List<MetroFacts> candidates, List<Objective> objectives, List<Constraint> constraints, Map<String,Double> weights, int minMetros, int maxMetros)
extends Record

Everything a Solver needs.

Constructor Details

SolveProblem

public SolveProblem(DesignContext context,
 List<MetroFacts> candidates,
 List<Objective> objectives,
 List<Constraint> constraints,
 Map<String,Double> weights,
 int minMetros,
 int maxMetros)

Validates the sizes and makes the collections immutable.

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.

context

public DesignContext context()

Returns the value of the context record component.

Returns:

the value of the context record component

candidates

public List<MetroFacts> candidates()

Returns the value of the candidates record component.

Returns:

the value of the candidates record component

objectives

public List<Objective> objectives()

Returns the value of the objectives record component.

Returns:

the value of the objectives record component

constraints

public List<Constraint> constraints()

Returns the value of the constraints record component.

Returns:

the value of the constraints record component

weights

public Map<String,Double> weights()

Returns the value of the weights record component.

Returns:

the value of the weights record component

minMetros

public int minMetros()

Returns the value of the minMetros record component.

Returns:

the value of the minMetros record component

maxMetros

public int maxMetros()

Returns the value of the maxMetros record component.

Returns:

the value of the maxMetros record component
