Constructor Detail

### AnnotatedSequenceDB

    public AnnotatedSequenceDB(SequenceDB parent,
                               SequenceAnnotator a)

Method Detail

### getParent

    public SequenceDB getParent()

  Get the original sequenceDB from this annotated sequenceDB.

### getName

    public String getName()

  Description copied from interface: `SequenceDBLite`
  Get the name of this sequence database.

  Specified by:
    `getName` in interface `SequenceDBLite`
  Returns:
    the name of the sequence database, which may be null.

### getSequence

    public Sequence getSequence(String id)
                         throws BioException

  Description copied from interface: `SequenceDBLite`
  Retrieve a single sequence by its id.

  Specified by:
    `getSequence` in interface `SequenceDBLite`
  Parameters:
    `id` - the id to retrieve by
  Returns:
    the Sequence with that id
  Throws:
    `IllegalIDException` - if the database doesn't know about the id
    `BioException` - if there was a failure in retrieving the sequence

### ids

    public Set ids()

  Description copied from interface: `SequenceDB`
  Get an immutable set of all of the IDs in the database. The ids are legal arguments to getSequence.

  Specified by:
    `ids` in interface `SequenceDB`
  Returns:
    a Set of ids - at the moment, strings

### sequenceIterator

    public SequenceIterator sequenceIterator()

  Description copied from interface: `SequenceDB`
  Returns a SequenceIterator over all sequences in the database. The order of retrieval is undefined.

  Specified by:
    `sequenceIterator` in interface `SequenceDB`
  Overrides:
    `sequenceIterator` in class `AbstractSequenceDB`
  Returns:
    a SequenceIterator over all sequences

### doAnnotation

    protected Sequence doAnnotation(Sequence seq)
                             throws BioException

  Apply the annotation to a sequence.

  Parameters:
    `seq` - the sequence to annotate.
  Throws:
    `BioException`
