Package ubic.gemma.core.loader.genome.gene.ncbi.homology

Class HomologeneServiceImpl

java.lang.Object

ubic.gemma.core.loader.genome.gene.ncbi.homology.HomologeneServiceImpl

All Implemented Interfaces:

HomologeneService

public class HomologeneServiceImpl
extends Object
implements HomologeneService

Reads in the homologene list as specified in the Gemmea.properties file. Loads the list at startup and keeps a mapping off.

You almost certainly want to call refresh() before using this service. This is done automatically if you use the HomologeneServiceFactory to lazy-load this service.

Method Details

getHomologue

public Gene getHomologue(Gene gene,
 Taxon taxon)

Specified by:

getHomologue in interface HomologeneService

Parameters:

gene - gene

taxon - desired taxon to find homologue in

Returns:

Finds the homologue of the given gene for the taxon specified, or null if there is no homologue

getHomologues

public Collection<Gene> getHomologues(Gene gene)

Specified by:

getHomologues in interface HomologeneService

Parameters:

gene - gene

Returns:

Collection of genes found in Gemma that are homologous with the given gene. Empty if no homologues or gene lacks homologue information, or null if not ready.

getHomologues

public Collection<Long> getHomologues(Long ncbiId)

Specified by:

getHomologues in interface HomologeneService

Parameters:

ncbiId - gene ncbi id

Returns:

A collection of NCBI gene ids that are homologous with the given NCBI Gene Id

refresh

public void refresh()
             throws IOException

Description copied from interface: HomologeneService

Refresh homologene data.

Specified by:

refresh in interface HomologeneService

Throws:

IOException

getHomologueValueObject

public GeneValueObject getHomologueValueObject(Long geneId,
 String taxonCommonName)

Specified by:

getHomologueValueObject in interface HomologeneService

Parameters:

geneId - gene id

taxonCommonName - desired taxon to find homologue in

Returns:

Finds the homologue of the given gene for the taxon specified, or null if there is no homologue

getNCBIGeneIdsInGroup

public Collection<Long> getNCBIGeneIdsInGroup(long homologeneGroupId)

Given an NCBI Homologene Group ID returns a list of all the NCBI Gene Ids in the given group

Specified by:

getNCBIGeneIdsInGroup in interface HomologeneService

Returns:

Collection of NCBI Gene Ids, or null if not ready.
