org.biojava.bio.symbol.IntegerAlphabet
An efficient implementation of an Alphabet over the infinite set of integer values.
This class can be used to represent lists of integer numbers as a SymbolList with the alphabet IntegerAlphabet. These lists can then be annotated with features, or fed into dynamic-programming algorithms, or processed as per any other SymbolList object.
Object identity should be used to decide if two IntegerSymbol objects are the same. IntegerAlphabet ensures that all IntegerSymbol instances are canonicalized.

public static IntegerAlphabet.SubIntegerAlphabet getSubAlphabet(int min, int max) throws java.lang.IllegalArgumentException
IntegerAlphabet

Useful for making CrossProductAlphabets with other FiniteAlphabet
s.
min
- the lower bound of the Alphabetmax
- the upper bound of the Alphabet
java.lang.IllegalArgumentException
- if max < minpublic static SymbolList fromArray(int[] iArray)
The returned object is a view onto the underlying array, and does not copy it. Changes made to the original array will alter the symulting SymbolList.
iArray
- the array of integers to view
public static IntegerAlphabet getInstance()
public IntegerAlphabet.IntegerSymbol getSymbol(int val)
val
- the int to view
public Symbol getGapSymbol()
Alphabet
Get the 'gap' ambiguity symbol that is most appropriate for this alphabet.
In general, this will be a BasisSymbol that represents a list of AlphabetManager.getGapSymbol() the same length as the getAlphabets list.

public Symbol getSymbol(java.util.List symList) throws IllegalSymbolException
Alphabet
Get a symbol from the Alphabet which corresponds to the specified ordered list of symbols.
The symbol at i in the list must be a member of the i'th alphabet in getAlphabets. If all of the symbols in rl are atomic, then the resulting symbol will also be atomic. If any one of them is an ambiguity symbol then the resulting symbol will be the appropriate ambiguity symbol.

symList
- A list of Symbol instances
IllegalSymbolException
- if the members of rl are
not Symbols over the alphabets returned from
getAlphabets
public Symbol getAmbiguity(java.util.Set symSet) throws IllegalSymbolException
Alphabet
Get a symbol that represents the set of symbols in syms.
Syms must be a set of Symbol instances each of which is contained within this alphabet. This method is used to retrieve ambiguity symbols.
getAmbiguity
in interface Alphabet
symSet
- the Set of Symbols that will be found in getMatches of the
returned symbol
IllegalSymbolException
public boolean contains(Symbol s)
Alphabet
Returns whether or not this Alphabet contains the symbol.
An alphabet contains an ambiguity symbol iff the ambiguity symbol's getMatches() returns an alphabet that is a proper sub-set of this alphabet. That means that every one of the symbols that could match the ambiguity symbol is also a member of this alphabet.
contains
in interface Alphabet
s
- the Symbol to check
public void validate(Symbol s) throws IllegalSymbolException
Alphabet
Throws a precanned IllegalSymbolException if the symbol is not contained within this Alphabet.
This function is used all over the code to validate symbols as they enter a method. Also, the code is littered with catches for IllegalSymbolException. There is a preferred style of handling this, which should be covererd in the package documentation.
