    public class DummySequenceDB

extends AbstractSequenceDB
implements SequenceDB

`DummySequenceDB` is an implementation which contains only a `DummySequence`. It will return the same `DummySequence` instance regardless of the sequence id used to retrieve a sequence.

Constructor Detail

### DummySequenceDB

    public DummySequenceDB(java.lang.String name)

Method Detail

### ids

    public java.util.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

### getName

    public java.lang.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(java.lang.String id)
                         throws IllegalIDException,
                                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

### addSequence

    public void addSequence(Sequence seq)
                     throws IllegalIDException,
                            BioException,
                            ChangeVetoException

  Description copied from interface: `SequenceDBLite`
  Adds a sequence to the database.

  Specified by:
    `addSequence` in interface `SequenceDBLite`
  Overrides:
    `addSequence` in class `AbstractSequenceDB`
  Parameters:
    `seq` - the Sequence to add
  Throws:
    `IllegalIDException` - if a uniqe ID could not be generated for seq
    `BioException` - if something goes wrong with adding the sequence
    `ChangeVetoException` - if either the database does not allow sequences to be added or the modification was vetoed

### removeSequence

    public void removeSequence(java.lang.String id)
                        throws IllegalIDException,
                               BioException,
                               ChangeVetoException

  Description copied from interface: `SequenceDBLite`
  Remove the sequence associated with an ID from the database.

  Specified by:
    `removeSequence` in interface `SequenceDBLite`
  Overrides:
    `removeSequence` in class `AbstractSequenceDB`
  Parameters:
    `id` - the ID of the sequence to remove
  Throws:
    `IllegalIDException` - if there is no sequence for the ID
    `BioException` - if something failed while removing the sequence for that ID
    `ChangeVetoException` - if either the database does not allow sequences to be removed or the modification was vetoed
