Class INSDseqFormat

    java.lang.Object
      org.biojavax.bio.seq.io.RichSequenceFormat.BasicFormat
          org.biojavax.bio.seq.io.INSDseqFormat

All Implemented Interfaces:
  SequenceFormat, RichSequenceFormat

    public class INSDseqFormat

extends RichSequenceFormat.BasicFormat

Format reader for INSDseq files. This version of INSDseq format will generate and write RichSequence objects. Loosely Based on code from the old, deprecated, org.biojava.bio.seq.io.GenbankXmlFormat object. Understands http://www.ebi.ac.uk/embl/Documentation/DTD/INSDC_V1.4.dtd.txt Does NOT understand the "sites" keyword in INSDReference_position. Interprets this instead as an empty location. This is because there is no obvious way of representing the "sites" keyword in BioSQL. Note also that the INSDInterval tags and associate stuff are not read, as this is duplicate information to the INSDFeature_location tag which is already fully parsed. However, they are written on output, although there is no guarantee that the INSDInterval tags will exactly match the INSDFeature_location tag as it is not possible to exactly reflect its contents using these.

  1.5

Method Summary
`void` | `beginWriting()` Informs the writer that we want to start writing.
`boolean` | `canRead(BufferedInputStream stream)` Check to see if a given stream is in our format. A stream is in INSDseq format if the second XML line contains the phrase "http://www.ebi.ac.uk/dtd/INSD_INSDSeq.dtd".
`boolean` | `canRead(File file)` Check to see if a given file is in our format. Some formats may be able to determine this by filename, whilst others may have to open the file and read it to see what format it is in. A file is in INSDseq format if the second XML line contains the phrase "http://www.ebi.ac.uk/dtd/INSD_INSDSeq.dtd".
`void` | `finishWriting()` Informs the writer that are done writing.
`String` | `getDefaultFormat()` `getDefaultFormat` returns the String identifier for the default sub-format written by a `SequenceFormat` implementation.
`SymbolTokenization` | `guessSymbolTokenization(BufferedInputStream stream)` On the assumption that the stream is readable by this format (not checked), attempt to guess which symbol tokenization we should use to read it. Always returns a DNA tokenizer.
`SymbolTokenization` | `guessSymbolTokenization(File file)` On the assumption that the file is readable by this format (not checked), attempt to guess which symbol tokenization we should use to read it. For formats that only accept one tokenization, just return it without checking the file. For formats that accept multiple tokenizations, its up to you how you do it. Always returns a DNA tokenizer.
`boolean` | `readRichSequence(BufferedReader reader, SymbolTokenization symParser, RichSeqIOListener rlistener, Namespace ns)` Reads a sequence from the given buffered reader using the given tokenizer to parse sequence symbols.
`boolean` | `readSequence(BufferedReader reader, SymbolTokenization symParser, SeqIOListener listener)` Read a sequence and pass data on to a SeqIOListener.
`void` | `writeSequence(Sequence seq, Namespace ns)` Writes a sequence out to the outputstream given by beginWriting() using the default format of the implementing class. Namespace is ignored as INSDseq has no concept of it.
`void` | `writeSequence(Sequence seq, PrintStream os)` `writeSequence` writes a sequence to the specified PrintStream, using the default format.
`void` | `writeSequence(Sequence seq, String format, PrintStream os)` `writeSequence` writes a sequence to the specified `PrintStream`, using the specified format.

  Read a sequence and pass data on to a SeqIOListener.

  Parameters:
    `reader` - The stream of data to parse.
    `symParser` - A SymbolParser defining a mapping from character data to Symbols.
    `listener` - A listener to notify when data is extracted from the stream.

    public boolean readRichSequence(BufferedReader reader,
                                    SymbolTokenization symParser,
                                    RichSeqIOListener rlistener,
                                    Namespace ns)
                             throws IllegalSymbolException,
                                    IOException,
                                    ParseException

  Reads a sequence from the given buffered reader using the given tokenizer to parse sequence symbols. Events are passed to the listener, and the namespace used for sequences read is the one given. If the namespace is null, then the default namespace for the parser is used, which may depend on individual implementations of this interface.

  Parameters:
    `reader` - the input source
    `symParser` - the tokenizer which understands the sequence being read
    `rlistener` - the listener to send sequence events to
    `ns` - the namespace to read sequences into.
  Returns:
    true if there is more to read after this, false otherwise.
  Throws:
    `IllegalSymbolException` - if the tokenizer couldn't understand one of the sequence symbols in the file.
    `IOException` - if there was a read error.
    `ParseException`

### beginWriting

    public void beginWriting()
                      throws IOException

  Informs the writer that we want to start writing. This will do any initialisation required, such as writing the opening tags of an XML file that groups sequences together.

  Throws:
    `IOException` - if writing fails.

### finishWriting

    public void finishWriting()
                       throws IOException

  Informs the writer that are done writing. This will do any finalisation required, such as writing the closing tags of an XML file that groups sequences together.

  Throws:
    `IOException` - if writing fails.

### writeSequence

    public void writeSequence(Sequence seq,
                              PrintStream os)
                       throws IOException

  `writeSequence` writes a sequence to the specified PrintStream, using the default format.

  Parameters:
    `seq` - the sequence to write out.
    `os` - the printstream to write to.
  Throws:
    `IOException`

### writeSequence

    public void writeSequence(Sequence seq,
                              String format,
                              PrintStream os)
                       throws IOException

  `writeSequence` writes a sequence to the specified `PrintStream`, using the specified format.

  Parameters:
    `seq` - a `Sequence` to write out.
    `format` - a `String` indicating which sub-format of those available from a particular `SequenceFormat` implemention to use when writing.
    `os` - a `PrintStream` object.
  Throws:
    `IOException` - if an error occurs.

### writeSequence

    public void writeSequence(Sequence seq,
                              Namespace ns)
                       throws IOException

  Writes a sequence out to the outputstream given by beginWriting() using the default format of the implementing class. If namespace is given, sequences will be written with that namespace, otherwise they will be written with the default namespace of the implementing class (which is usually the namespace of the sequence itself). If you pass this method a sequence which is not a RichSequence, it will attempt to convert it using RichSequence.Tools.enrich(). Obviously this is not going to guarantee a perfect conversion, so it's better if you just use RichSequences to start with! Namespace is ignored as INSDseq has no concept of it.

  Parameters:
    `seq` - the sequence to write
    `ns` - the namespace to write it with
  Throws:
    `IOException` - in case it couldn't write something

### getDefaultFormat

    public String getDefaultFormat()

  `getDefaultFormat` returns the String identifier for the default sub-format written by a `SequenceFormat` implementation.

  Returns:
    a `String`.
