getNucleotide

public static FiniteAlphabet getNucleotide()

Return the Nucleotide alphabet.

Returns:

a flyweight version of the Nucleotide alphabet

createNucleotide

public static SymbolList createNucleotide(String nucleotide)
                                   throws IllegalSymbolException

Return a new Nucleotide SymbolList for nucleotide.

Parameters:

nucleotide - a String to parse into Nucleotide

Returns:

a SymbolList created form nucleotide

Throws:

IllegalSymbolException - if nucleotide contains any non-Nucleotide characters

createNucleotideSequence

public static Sequence createNucleotideSequence(String nucleotide,
                                                String name)
                                         throws IllegalSymbolException

Return a new Nucleotide Sequence for nucleotide.

Parameters:

nucleotide - a String to parse into Nucleotide

name - a String to use as the name

Returns:

a Sequence created form nucleotide

Throws:

IllegalSymbolException - if nucleotide contains any non-Nucleotide characters

index

public static int index(Symbol sym)
                 throws IllegalSymbolException

Return an integer index for a symbol - compatible with forIndex.

The index for a symbol is stable accross virtual machines & invocations.

Parameters:

sym - the Symbol to index

Returns:

the index for that symbol

Throws:

IllegalSymbolException - if sym is not a member of the Nucleotide alphabet

forIndex

public static Symbol forIndex(int index)
                       throws IndexOutOfBoundsException

Return the symbol for an index - compatible with index.

The index for a symbol is stable accross virtual machines & invocations.

Parameters:

index - the index to look up

Returns:

the symbol at that index

Throws:

IndexOutOfBoundsException - if index is not between 0 and 3

complement

public static Symbol complement(Symbol sym)
                         throws IllegalSymbolException

Complement the symbol.

Parameters:

sym - the symbol to complement

Returns:

a Symbol that is the complement of sym

Throws:

IllegalSymbolException - if sym is not a member of the Nucleotide alphabet

forSymbol

public static Symbol forSymbol(char token)
                        throws IllegalSymbolException

Retrieve the symbol for a symbol.

Parameters:

token - the char to look up

Returns:

the symbol for that char

Throws:

IllegalSymbolException - if the char does not belong to {a, g, c, t, u}

complement

public static SymbolList complement(SymbolList list)
                             throws IllegalAlphabetException

Retrieve a complement view of list.

Parameters:

list - the SymbolList to complement

Returns:

a SymbolList that is the complement

Throws:

IllegalAlphabetException - if list is not a complementable alphabet

reverseComplement

public static SymbolList reverseComplement(SymbolList list)
                                    throws IllegalAlphabetException

Retrieve a reverse-complement view of list.

Parameters:

list - the SymbolList to complement

Returns:

a SymbolList that is the complement

Throws:

IllegalAlphabetException - if list is not a complementable alphabet

complementTable

public static ReversibleTranslationTable complementTable()

Get a translation table for complementing Nucleotide symbols.

Since:

1.1

nucleotideToken

public static char nucleotideToken(Symbol sym)
                            throws IllegalSymbolException
