Constructor Detail

ItemToObjectTranslator

public ItemToObjectTranslator(Model model,
                              ObjectStore os)
                       throws ObjectStoreException

Constructor

Parameters:

model - the Model used in business object creation

os - an ObjectStore containing the Item data that we will be translating. Note that the contents of the objectstore must remain constant for IDs to not clash - newly written objects will not be accessible by their ID. This translator assumes that the Item identifier field contains some string, an underscore, then some number with no leading zeros.

Throws:

ObjectStoreException - if the initialisation query fails

Method Detail

idToIdentifier

public java.lang.String idToIdentifier(java.lang.Integer id)

Turn an object id into an item identifier.

Parameters:

id - an InterMineObject id

Returns:

the corresponding item identifier

translateIdToIdentifier

public java.lang.Object translateIdToIdentifier(java.lang.Integer id)

Translate an object id into a native identifier.

Specified by:

translateIdToIdentifier in class Translator

Parameters:

id - the object id

Returns:

an object that represents the underlying object's identifier

identifierToId

public java.lang.Integer identifierToId(java.lang.String identifier)

Turn an item identifier into an object id.

Parameters:

identifier - an item identifier

Returns:

the corresponding InterMineObject id

translateQuery

public Query translateQuery(Query query)
                     throws ObjectStoreException

Translate a query.

Specified by:

translateQuery in class Translator

Parameters:

the translated object

translateFromDbObject

public java.lang.Object translateFromDbObject(java.lang.Object o)
