Class SoftMaskedAlphabet.CaseSensitiveTokenization

java.lang.Object

org.biojava.utils.Unchangeable

org.biojava.bio.symbol.SoftMaskedAlphabet.CaseSensitiveTokenization

All Implemented Interfaces:

Annotatable, SymbolTokenization, Changeable

Enclosing class:

SoftMaskedAlphabet

public class SoftMaskedAlphabet.CaseSensitiveTokenization
extends Unchangeable
implements SymbolTokenization

This SymbolTokenizer works with a delegate to softmask symbol tokenization as appropriate. It should only be used in combination with a SoftMaskedAlphabet. You will never instantiate one of these yourself.

Method Detail

getAnnotation

public Annotation getAnnotation()

Description copied from interface: Annotatable

Should return the associated annotation object.

Specified by:

getAnnotation in interface Annotatable

Returns:

an Annotation object, never null

getAlphabet

public Alphabet getAlphabet()

Description copied from interface: SymbolTokenization

The alphabet to which this tokenization applies.

Specified by:

getAlphabet in interface SymbolTokenization

getTokenType

public SymbolTokenization.TokenType getTokenType()

Description copied from interface: SymbolTokenization

Determine the style of tokenization represented by this object.

Specified by:

getTokenType in interface SymbolTokenization

parseToken

public Symbol parseToken(String token)
                  throws IllegalSymbolException

Description copied from interface: SymbolTokenization

Returns the symbol for a single token.

The Symbol will be a member of the alphabet. If the token is not recognized as mapping to a symbol, an exception will be thrown.

Specified by:

parseToken in interface SymbolTokenization

Parameters:

token - the token to retrieve a Symbol for

Returns:

the Symbol for that token

Throws:

IllegalSymbolException - if there is no Symbol for the token

tokenizeSymbolList

public String tokenizeSymbolList(SymbolList sl)
                          throws IllegalSymbolException

Description copied from interface: SymbolTokenization

Return a string representation of a list of symbols.

Specified by:

tokenizeSymbolList in interface SymbolTokenization

Parameters:

sl - A SymbolList

Throws:

IllegalSymbolException

parseStream

public StreamParser parseStream(SeqIOListener l)

The current implementation only supports character parsing. Word or fixed width parsing is not yet supported.

Specified by:

parseStream in interface SymbolTokenization

Parameters:

l - the SeqIOListener to callback to.

Returns:

a StreamParser that the SeqIOListener talks to.

tokenizeSymbol

public String tokenizeSymbol(Symbol s)
                      throws IllegalSymbolException

Description copied from interface: SymbolTokenization

Return a token representing a single symbol.

Specified by:

tokenizeSymbol in interface SymbolTokenization

Parameters:

s - The symbol

Throws:

IllegalSymbolException - if the symbol isn't recognized.
