Method Detail

getOntologyFile

public static File getOntologyFile(Registry reg,
                                   String resourceName)

Returns where a resource should be cached locally, whether it current exists or not.

Parameters:

resourceName - one of the resources listed in org.biomoby.shared.Central

cacheRegistryOntology

public static File cacheRegistryOntology(Registry reg,
                                         String resourceName)
                                  throws Exception

Stores the given resource to a file for retrieval later with getOntologyFile().

Parameters:

resourceName - one of the resources listed in org.biomoby.shared.Central

Returns:

the file where the resource has been cached

Throws:

Exception

cacheRegistryOntology

public static File cacheRegistryOntology(Registry reg,
                                         String resourceName,
                                         long allowedAgeMillis)
                                  throws Exception

Stores the given resource to a file for retrieval later with getOntologyFile().

Parameters:

resourceName - one of the resources listed in org.biomoby.shared.Central

allowedAgeMillis - if the hached file exists and is less than this many milliseconds old, a new version will not be downloaded, if zero or negative, overwrite is forced.

Returns:

the file where the resource has been cached

Throws:

Exception
