Method Detail

getMutationProbs

public double[] getMutationProbs()

Specified by:

getMutationProbs in interface MutationFunction

getMutationSpectrum

public OrderNDistribution getMutationSpectrum()

Specified by:

getMutationSpectrum in interface MutationFunction

Returns:

null if the Distribution has not been set.

mutate

public SymbolList mutate(SymbolList syml)

Description copied from interface: MutationFunction

Produces a new SymbolList by mutation. Each position i in the SymbolList seq is mutated with probability getMutationProbs[i]. The new residue is selected at random from the Distribution mutation. The use of an array of probabilities allows the modelling of mutational hotspots. Position 0 in the array corresponds to the probability of the first residue of seq mutating. If the length of the array defined in getMutationProbs() is shorter than the length of the sequence the default behaivour of implementations will be to apply the last probability to each subsequence residue. A single member array will mutate all bases with equal probability.

Specified by:

mutate in interface MutationFunction

Parameters:

syml - the sequence to mutate

Returns:

The mutated sequence.

setMutationProbs

public void setMutationProbs(double[] muts)
                      throws ChangeVetoException

Description copied from interface: MutationFunction

Set the probability of a mutation occuring at a certain position Position 0 in the array corresponds to the probability of the first residue of seq mutating. If the length of the array defined in getMutationProbs() is shorter than the length of the sequence the default behaivour of implementations will be to apply the last probability to each subsequence residue. A single member array will mutate all bases with equal probability.

Specified by:

setMutationProbs in interface MutationFunction

Parameters:

muts - an array of double values representing mutation probabilities

Throws:

ChangeVetoException - if a ChangeListener vetoes the change.

setMutationSpectrum

public void setMutationSpectrum(OrderNDistribution odn)
                         throws ChangeVetoException

Description copied from interface: MutationFunction

Sets the Distribution of Symbols that will be selected from when a mutation occurs. An OrderNDistribution is used so that you can model a situation where the identity of the 'mutant' Symbol is dependent on the original Symbol. The primary use is to prevent Symbols mutating to themselves. Another use would be to model transitions and transversions.

Specified by:

setMutationSpectrum in interface MutationFunction

Parameters:

odn - the Distribution of 'mutant' bases to choose from.

Throws:

ChangeVetoException - if a ChangeListener vetoes the change.

isUnchanging

public boolean isUnchanging(ChangeType ct)

Description copied from interface: Changeable

A particular ChangeType can never be raised by this Changeable.

If this returns true, then it is guaranteed that change events of this type (and all child types) can never under any circumstances be fired by this Changeable instance. If it returns false, that does not mean that this type of event will or even can be raised, but that it is worth registering listeners incase.

Specified by:

isUnchanging in interface Changeable

Parameters:

ct - the ChangeType to check

Returns:

true if ChangeEvents of this type are guaranteed to never be fired

removeChangeListener

public void removeChangeListener(ChangeListener c)

Description copied from interface: Changeable

Remove a listener that was interested in all types of changes.

Specified by:

removeChangeListener in interface Changeable

Parameters:

c - a ChangeListener to remove

addChangeListener

public void addChangeListener(ChangeListener cl)

Description copied from interface: Changeable

Add a listener that will be informed of all changes.

Specified by:

addChangeListener in interface Changeable

Parameters:

cl - the ChangeListener to add

addChangeListener

public void addChangeListener(ChangeListener cl,
                              ChangeType ct)

Description copied from interface: Changeable

Add a listener that will be informed of changes of a given type.

Specified by:

addChangeListener in interface Changeable

Parameters:

cl - the ChangeListener

ct - the ChangeType it is to be informed of

removeChangeListener

public void removeChangeListener(ChangeListener cl,
                                 ChangeType ct)

Description copied from interface: Changeable

Remove a listener that was interested in a specific types of changes.

Specified by:

removeChangeListener in interface Changeable

Parameters:

cl - a ChangeListener to remove

ct - the ChangeType that it was interested in
