Constructor Detail

DASSequenceDB

public DASSequenceDB(java.net.URL dataSourceURL)
              throws BioException

Throws:

BioException

Method Detail

filter

public FeatureHolder filter(FeatureFilter ff)

Description copied from interface: SequenceDB

Query features attached to all sequences in this database. This is equivalent to applying filter to all sequences then merging the results.

Specified by:

filter in interface SequenceDB

Parameters:

ff - a FeatureFilter.

allEntryPointsDB

public SequenceDBLite allEntryPointsDB()

getURL

public java.net.URL getURL()

Return the URL of the reference server for this database.

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 BioException,
                            IllegalIDException

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 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

addSequence

public void addSequence(Sequence seq)
                 throws ChangeVetoException

Description copied from interface: SequenceDBLite

Adds a sequence to the database.

Specified by:

addSequence in interface SequenceDBLite

Parameters:

seq - the Sequence to add

Throws:

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 ChangeVetoException

Description copied from interface: SequenceDBLite

Remove the sequence associated with an ID from the database.

Specified by:

removeSequence in interface SequenceDBLite

Parameters:

id - the ID of the sequence to remove

Throws:

ChangeVetoException - if either the database does not allow sequences to be removed or the modification was vetoed

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

Returns:

a SequenceIterator over all sequences
