Method Detail

nextRichSequence

public RichSequence nextRichSequence()
                              throws NoSuchElementException,
                                     BioException

Specified by:

nextRichSequence in interface RichSequenceIterator

Throws:

NoSuchElementException

BioException

hasNext

public boolean hasNext()

Description copied from interface: BioEntryIterator

Returns whether there are more sequences to iterate over.

Specified by:

hasNext in interface BioEntryIterator

Specified by:

hasNext in interface SequenceIterator

Returns:

true if there are more sequences to get and false otherwise

nextBioEntry

public BioEntry nextBioEntry()
                      throws NoSuchElementException,
                             BioException

Specified by:

nextBioEntry in interface BioEntryIterator

Throws:

NoSuchElementException

BioException

nextSequence

public Sequence nextSequence()
                      throws NoSuchElementException,
                             BioException

Description copied from interface: SequenceIterator

Returns the next sequence in the iterator.

Specified by:

nextSequence in interface SequenceIterator

Returns:

the next Sequence

Throws:

NoSuchElementException - if you call nextSequence when hasNext returns false

BioException - if for any reason the sequence could not be retrieved
