Constructor Detail

### SeqIOFilter

    public SeqIOFilter(SeqIOListener delegate)

  Create a new SeqIOFilter that will forward events on to another listener.

  Parameters:
    `delegate` - the SeqIOListener to wrap

Method Detail

### getDelegate

    public SeqIOListener getDelegate()

  Retrieve the delegate that is wrapped.

  Returns:
    the SeqIOListener delegate

### startSequence

    public void startSequence()
                       throws ParseException

  Description copied from interface: `SeqIOListener`
  Start the processing of a sequence. This method exists primarily to enforce the life-cycles of SeqIOListener objects.

  Specified by:
    `startSequence` in interface `SeqIOListener`
  Throws:
    `ParseException`

### endSequence

    public void endSequence()
                     throws ParseException

  Description copied from interface: `SeqIOListener`
  Notify the listener that processing of the sequence is complete.

  Specified by:
    `endSequence` in interface `SeqIOListener`
  Throws:
    `ParseException`

### setName

    public void setName(String name)
                 throws ParseException

  Description copied from interface: `SeqIOListener`
  Notify the listener that the current sequence is generally known by a particular name.

  Specified by:
    `setName` in interface `SeqIOListener`
  Parameters:
    `name` - the String that should be returned by getName for the sequence being parsed
  Throws:
    `ParseException`

### setURI

    public void setURI(String uri)
                throws ParseException

  Description copied from interface: `SeqIOListener`
  Notify the listener of a URI identifying the current sequence.

  Specified by:
    `setURI` in interface `SeqIOListener`
  Throws:
    `ParseException`

### addSymbols

    public void addSymbols(Alphabet alpha,
                           Symbol[] syms,
                           int start,
                           int length)
                    throws IllegalAlphabetException

  Description copied from interface: `SeqIOListener`
  Notify the listener of symbol data. All symbols passed to this method are guarenteed to be contained within the specified alphabet. Generally all calls to a given Listener should have the same alphabet -- if not, the listener implementation is likely to throw an exception

  Specified by:
    `addSymbols` in interface `SeqIOListener`
  Parameters:
    `alpha` - The alphabet of the symbol data
    `syms` - An array containing symbols
    `start` - The start offset of valid data within the array
    `length` - The number of valid symbols in the array
  Throws:
    `IllegalAlphabetException` - if we can't cope with this alphabet.

### addSequenceProperty

    public void addSequenceProperty(Object key,
                                    Object value)
                             throws ParseException

  Description copied from interface: `SeqIOListener`
  Notify the listener of a sequence-wide property. This might be stored as an entry in the sequence's annotation bundle.

  Specified by:
    `addSequenceProperty` in interface `SeqIOListener`
  Throws:
    `ParseException`

### startFeature

    public void startFeature(Feature.Template templ)
                      throws ParseException

  Description copied from interface: `SeqIOListener`
  Notify the listener that a new feature object is starting. Every call to startFeature should have a corresponding call to endFeature. If the listener is concerned with a hierarchy of features, it should maintain a stack of `open' features.

  Specified by:
    `startFeature` in interface `SeqIOListener`
  Throws:
    `ParseException`

### endFeature

    public void endFeature()
                    throws ParseException

  Description copied from interface: `SeqIOListener`
  Mark the end of data associated with one specific feature.

  Specified by:
    `endFeature` in interface `SeqIOListener`
  Throws:
    `ParseException`

### addFeatureProperty

    public void addFeatureProperty(Object key,
                                   Object value)
                            throws ParseException

  Description copied from interface: `SeqIOListener`
  Notify the listener of a feature property.

  Specified by:
    `addFeatureProperty` in interface `SeqIOListener`
  Throws:
    `ParseException`
