Method Detail

getUserTypes

public List<URI> getUserTypes(FedoraId resourceId,
                              String sessionId,
                              Supplier<RdfStream> rdfProvider)

Gets the user RDF types for the specified resource from the cache. First, the session's cache is checked. If the types were not found, then the global cache is checked. If not in either cache, then the rdfProvider is called to load the resource's RDF from which the types are parsed, cached, and returned. This method should NOT be called on binary resources.

Specified by:

getUserTypes in interface UserTypesCache

Parameters:

resourceId - the id of the resource

sessionId - the id of the current session

rdfProvider - the provider that is called, if needed, to load the resource's rdf

Returns:

the resource's user RDF types

cacheUserTypes

public void cacheUserTypes(FedoraId resourceId,
                           RdfStream rdf,
                           String sessionId)

Extracts the user RDF types from the RDF and caches them in the session level cache.

Specified by:

cacheUserTypes in interface UserTypesCache

Parameters:

resourceId - the id of the resource

rdf - the resource's RDF

sessionId - the session to cache the types in

cacheUserTypes

public void cacheUserTypes(FedoraId resourceId,
                           List<URI> userTypes,
                           String sessionId)

Caches the user RDF types in the session level cache.

Specified by:

cacheUserTypes in interface UserTypesCache

Parameters:

resourceId - the id of the resource

userTypes - the resource's types

sessionId - the session to cache the types in

mergeSessionCache

public void mergeSessionCache(String sessionId)

Merges the session level cache into the global cache.

Specified by:

mergeSessionCache in interface UserTypesCache

Parameters:

sessionId - the id of the session to merge

dropSessionCache

public void dropSessionCache(String sessionId)

Drops a session level cache without merging it into the global cache.

Specified by:

dropSessionCache in interface UserTypesCache

Parameters:

sessionId - the id of the session cache to drop
