## org.biojava.bio.seq.io
Class SequenceBuilderBase

    java.lang.Object
      org.biojava.bio.seq.io.SequenceBuilderBase

All Implemented Interfaces:
  SeqIOListener, SequenceBuilder

Direct Known Subclasses:
  SequenceDBSequenceBuilder, SimpleAssemblyBuilder, SimpleSequenceBuilder, SmartSequenceBuilder

    public abstract class SequenceBuilderBase

extends Object
implements SequenceBuilder

Basic SequenceBuilder implementation which accumulates all notified information. Subclass this to implement specific Sequence implementations. More functionality is offered by the `SimpleRichSequenceBuilder`.

Version:
  1.2 [newio proposal]
Author:
  Thomas Down, David Huen (modified SimpleSequence to make this)

### uri

    protected String uri

### annotation

### seq

    protected Sequence seq

Constructor Detail

### SequenceBuilderBase

    public SequenceBuilderBase()

Method Detail

### startSequence

    public void startSequence()

  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`

### endSequence

    public void endSequence()

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

  Specified by:
    `endSequence` in interface `SeqIOListener`

### setName

    public void setName(String name)

  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

### setURI

    public void setURI(String uri)

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

  Specified by:
    `setURI` in interface `SeqIOListener`

### addSymbols

    public abstract void addSymbols(Alphabet alpha,
                                    Symbol[] syms,
                                    int pos,
                                    int len)
                             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
    `pos` - The start offset of valid data within the array
    `len` - 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)

  Add an annotation-bundle entry to the sequence. If the annotation key isn't currently defined, the value is added directly. Otherwise:
  - If the current value implements the Collection interface, the new value is added to that collection.
  - Otherwise, the current value is replaced by a List object containing the old value then the new value in that order.

  Specified by:
    `addSequenceProperty` in interface `SeqIOListener`

### startFeature

    public void startFeature(Feature.Template templ)

  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`

### addFeatureProperty

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

  Add an annotation-bundle entry to the feature. If the annotation key isn't currently defined, the value is added directly. Otherwise:
  - If the current value implements the Collection interface, the new value is added to that collection.
  - Otherwise, the current value is replaced by a List object containing the old value then the new value in that order.

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

### endFeature

    public void endFeature()

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

  Specified by:
    `endFeature` in interface `SeqIOListener`

### makeSequence

    public Sequence makeSequence()
                          throws BioException

  Description copied from interface: `SequenceBuilder`
  Return the Sequence object which has been constructed by this builder. This method is only expected to succeed after the endSequence() notifier has been called.

  Specified by:
    `makeSequence` in interface `SequenceBuilder`
  Throws:
    `BioException`

### addProperty

    protected void addProperty(Annotation ann,
                               Object key,
                               Object value)
