## org.biojava.bio.symbol
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.
