## org.biojavax.bio.taxa.io
Class SimpleNCBITaxonomyLoader

    java.lang.Object
      org.biojavax.bio.taxa.io.SimpleNCBITaxonomyLoader

All Implemented Interfaces:
  NCBITaxonomyLoader

    public class SimpleNCBITaxonomyLoader

extends Object
implements NCBITaxonomyLoader

Loads NCBI taxon information from names.dmp and nodes.dmp, which are two of the files in the archive downloadable at ftp://ftp.ncbi.nih.gov/pub/taxonomy/ . This simple implementation makes no attempt to process deletions or merges - it merely creates instances as it goes along, reusing any that may already exist.

Since:
  1.5

Constructor Summary
`SimpleNCBITaxonomyLoader()`

Method Summary
`protected NCBITaxon` | `findTaxon(Object[] theKeys)`
`NCBITaxon` | `readName(BufferedReader names)` Reads the next entry from the names.dmp file and returns the corresponding NCBITaxon object with the name added in already.
`NCBITaxon` | `readNode(BufferedReader nodes)` Reads the next entry from the nodes.dmp file and returns the corresponding NCBITaxon object.

Constructor Detail

### SimpleNCBITaxonomyLoader

    public SimpleNCBITaxonomyLoader()

Method Detail

### readNode

    public NCBITaxon readNode(BufferedReader nodes)
                       throws IOException,
                              ParseException

  Reads the next entry from the nodes.dmp file and returns the corresponding NCBITaxon object.

  Specified by:
    `readNode` in interface `NCBITaxonomyLoader`
  Parameters:
    `nodes` - something that reads the nodes.dmp file
  Returns:
    the next NCBITaxon object in the file, or null if the file has ended.
  Throws:
    `IOException`
    `ParseException`

### findTaxon

    protected NCBITaxon findTaxon(Object[] theKeys)

### readName

    public NCBITaxon readName(BufferedReader names)
                       throws IOException,
                              ParseException

  Reads the next entry from the names.dmp file and returns the corresponding NCBITaxon object with the name added in already. Note that this does not clear out existing names from the taxon, it only adds them. Use the code snippet below if you want to clear out the names first: `for (Iterator i = taxon.getNameClasses().iterator(); i.hasNext(); ) { taxon.getNames((String)i.next()).clear(); }`

  Specified by:
    `readName` in interface `NCBITaxonomyLoader`
  Parameters:
    `names` - something that reads the names.dmp file
  Returns:
    the NCBITaxon object corresponding to the next entry in the file, or null if the file has ended.
  Throws:
    `IOException`
    `ParseException`
