Field Detail

type

private Type type

The type of this ProbDistr. Note that this is not updated by methods such as remove(eu.simuline.relana.model.Deficiency) or add(eu.simuline.relana.model.Deficiency) but only set and used in the initialization process.

def2prob

private Map<Deficiency,BigDecimal> def2prob

validators

private Map<ProbDistr.Inverter,ProbDistr.Validator> validators

Constructor Detail

ProbDistr

public ProbDistr(Type type,
                 Map<Deficiency,BigDecimal> def2prob)

ProbDistr

public ProbDistr(Type type,
                 Map<Deficiency,ProbDistr> old2ProbDistr,
                 Map<Deficiency,BigDecimal> def2prob)

Method Detail

checkIn01

private static void checkIn01(Map<Deficiency,BigDecimal> def2prob)

init

private ProbDistr.Validator init(ProbDistr.Inverter inv,
                                 Stack<Deficiency> minDefs,
                                 Set<DeficiencyNode> nMinNodes)

Describe init method here.

Parameters:

inv - determines whether analysis is bottom up or top down. Here: just exchanges min and max.

minDefs - Invoked with empty set; method collects the minimal Deficiencys.

nMinNodes - Invoked with empty set; method collects sort of deep copies of the non-minimal DeficiencyNodes here.

Returns:

a raw Validator for this distribution. Here, raw means that nothing is done but invocation of the constructor.

getValidator

ProbDistr.Validator getValidator(ProbDistr.Inverter inv)

Parameters:

inv - determines whether analysis is bottom up or top down.

Returns:

a Validator.

getType

private Type getType()

getProb

public BigDecimal getProb(Deficiency def)

validate

public void validate()

validateUp

private void validateUp(ProbDistr.Inverter inv)

remove

ProbDistr remove(Deficiency def)

add

ProbDistr add(Deficiency def)

toString

public String toString()

Overrides:

toString in class Object
