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.
String	lookup(Context context, DSpaceObject dso, Class<? extends Identifier> identifier)
void	register(Context context, DSpaceObject dso)
void	register(Context context, DSpaceObject dso, 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 any identifiers necessary based on the capabilities of all providers in the service.

DSpaceObject	resolve(Context context, String identifier) This will resolve a DSpaceObject based on a provided Identifier.

Method Detail

lookup

String lookup(Context context,
              DSpaceObject dso,
              Class<? extends Identifier> identifier)

Parameters:

context -

dso -

identifier -

Returns:

resolve

DSpaceObject resolve(Context context,
                     String identifier)
                     throws IdentifierNotFoundException,
                            IdentifierNotResolvableException

This will resolve a DSpaceObject based on a provided Identifier. The Service will interrogate the providers in no particular order and return the first successful result discovered. If no resolution is successful, the method will return null if no object is found. TODO: Verify null is returned.

Parameters:

context -

identifier -

Returns:

Throws:

IdentifierNotFoundException

IdentifierNotResolvableException

reserve
