Method Details

[hide private]

init(self)
(Constructor)

source code

Create the object.

This method should be replaced by any derived class to do something useful.

Overrides: object.__init__

len(self)
(Length operator)

source code

Return the number of records.

This method should be replaced by any derived class to do something useful.

getitem(self, i)
(Indexing operator)

source code

Return the requested record.

This method should be replaced by any derived class to do something
useful.

It should NOT touch the value of self._n

next(self)

source code

Return the next record in the file.

This method should be replaced by any derived class to do something useful.

Overrides: SequenceIterator.next: (inherited documentation)

iter(self)

source code

Iterate over the entries as a SeqRecord objects.

Example usage for Fasta files:

myFile = open("example.fasta","r")
myFastaReader = FastaIterator(myFile)
for record in myFastaReader:
    print record.id
    print record.seq
myFile.close()

Overrides: SequenceIterator.__iter__: (inherited documentation)
