Alphabet

public Alphabet()

Method Detail

checkConsistency

public final boolean checkConsistency(Alphabet a)

Checks if this Alphabet is consistent consistent with another Alphabet, i.e. both Alphabets use the same symbols.

Parameters:

a - the second Alphabet

Returns:

true if the Alphabets are consistent, false otherwise

getMin

public abstract double getMin()

Returns the minimal value of theAlphabet.

Returns:

the minimal value of the Alphabet

length

public abstract double length()

Returns the length of the Alphabet.

Returns:

the length of the Alphabet

toString

public abstract String toString()

Overrides:

toString in class Object

getCurrentParameterSet

public abstract InstanceParameterSet<? extends Alphabet> getCurrentParameterSet()
                                                                         throws Exception

Description copied from interface: InstantiableFromParameterSet

Returns the InstanceParameterSet that has been used to instantiate the current instance of the implementing class. If the current instance was not created using an InstanceParameterSet, an equivalent InstanceParameterSet should be returned, so that an instance created using this InstanceParameterSet would be in principle equal to the current instance.

Specified by:

getCurrentParameterSet in interface InstantiableFromParameterSet

Returns:

the current InstanceParameterSet

Throws:

Exception - if the InstanceParameterSet could not be returned
