                               boolean hasOrderedDomain,
                               boolean isInFrequencyDomain)

Method Detail

getUnit

public IUnit getUnit()

Description copied from interface: IProbabilityFunction

Returns the unit of the probability functions domain.

Specified by:

getUnit in interface IProbabilityFunction

Returns:

unit of the probability functions domain.

hasOrderedDomain

public boolean hasOrderedDomain()

Description copied from interface: IProbabilityFunction

If the domain of the probability functions is ordered, true is returned; false otherwise.

Specified by:

hasOrderedDomain in interface IProbabilityFunction

Returns:

True, if the domain is ordered.

isInFrequencyDomain

public boolean isInFrequencyDomain()

Description copied from interface: IProbabilityFunction

True, if the probability density function is in the frequency domain (frequency domain graph shows how much of the signal lies within each given frequency band over a range of frequencies). This means it is the result of a Fourier transformation.

Specified by:

isInFrequencyDomain in interface IProbabilityFunction

Returns:

True, if in frequency domain, false otherwise.

isInTimeDomain

public boolean isInTimeDomain()

Description copied from interface: IProbabilityFunction

True, if the probability density function is the time domain (a time domain graph shows how a signal changes over time). This means that it is not a result of a Fourier transform.

Specified by:

isInTimeDomain in interface IProbabilityFunction

Returns:

True, if in time domain; false otherwise.

setInFrequencyDomain

protected void setInFrequencyDomain(boolean isInFrequencyDomain)

setUnit

protected void setUnit(IUnit unit)

getRandomGenerator

public IRandomGenerator getRandomGenerator()

Returns:

the randomGenerator

setRandomGenerator

public void setRandomGenerator(IRandomGenerator randomGenerator)

Parameters:

randomGenerator - the randomGenerator to set
