Constructor Summary

IdentifierServiceImpl()

Method Summary

void	delete(Context context, DSpaceObject dso) Delete (Unbind) all identifiers registered for a specific DSpace item.
void	delete(Context context, DSpaceObject dso, String identifier) Used to Delete a Specific Identifier (for example a Handle, hdl:1234.5/6) The provider is responsible for Detecting and Processing the appropriate identifier, all Providers are interrogated, multiple providers can process the same identifier.

void	register(Context context, DSpaceObject object, String identifier) Used to Register a Specific Identifier (for example a Handle, hdl:1234.5/6) The provider is responsible for Detecting and Processing the appropriate identifier, all Providers are interrogated, multiple providers can process the same identifier.
void	reserve(Context context, DSpaceObject dso) Reserves identifiers for the item
void	reserve(Context context, DSpaceObject dso, String identifier) Used to Reserve a Specific Identifier (for example a Handle, hdl:1234.5/6) The provider is responsible for Detecting and Processing the appropriate identifier, all Providers are interrogated, multiple providers can process the same identifier.
DSpaceObject	resolve(Context context, String identifier) This will resolve a DSpaceObject based on a provided Identifier.
