Method Detail

getBeliefMasses

public HypothesesContainer getBeliefMasses()

Returns:

the hypotheses

setBeliefMasses

public void setBeliefMasses(HypothesesContainer beliefMasses)

Parameters:

beliefMasses - the hypotheses to set

getPignistic

public double getPignistic()

Description copied from interface: IBeliefContainer

Get the pignistic value (the mastery) stored in the BeliefContainer. The pignistic value is always a normalized mastery in [0,1].

Specified by:

getPignistic in interface IBeliefContainer

Returns:

the pignistic

setPignistic

public void setPignistic(double pignistic)

Description copied from interface: IBeliefContainer

Set the pignistic value (the mastery) stored in the BeliefContainer.

Specified by:

setPignistic in interface IBeliefContainer

Parameters:

pignistic - the pignistic to set

getPlausibility

public double getPlausibility()

Description copied from interface: IBeliefContainer

Get the plausibility value of the mastery stored in the BeliefContainer. It can be interpreted as a measure of how strong we believe in the computed pignistic value. A value of 0 means no trust at all and a value of 1 means we are absolutely sure about the estimated pignistic value.

Specified by:

getPlausibility in interface IBeliefContainer

Returns:

the plausibility

setPlausibility

public void setPlausibility(double plausibility)

Description copied from interface: IBeliefContainer

Set the plausibility value for the mastery stored in the BeliefContainer.

Specified by:

setPlausibility in interface IBeliefContainer

Parameters:

plausibility - the plausibility to set

isIndirectEvidenceUsed

public boolean isIndirectEvidenceUsed()

Description copied from interface: IBeliefContainer

Has indirect evidence been used to form the belief

Specified by:

isIndirectEvidenceUsed in interface IBeliefContainer

Returns:

the indirectEvidenceUsed

setIndirectEvidenceUsed

public void setIndirectEvidenceUsed(boolean indirectEvidenceUsed)

Description copied from interface: IBeliefContainer

Set whether indirect evidence been used to form the belief or not

Specified by:

setIndirectEvidenceUsed in interface IBeliefContainer

Parameters:

indirectEvidenceUsed - the indirectEvidenceUsed to set

toString

public String toString()

Overrides:

toString in class Object
