Constructor Detail

### MutationFunction.NoMutation

    public MutationFunction.NoMutation()

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
