Method Detail

updateSharedMaps

public void updateSharedMaps()

Called after a transaction commit() to transfer all the staged (thread-local) data over to the shared LRU cache.

Specified by:

updateSharedMaps in interface ILogicalResourceIdentCache

getLogicalResourceId

public java.lang.Long getLogicalResourceId(int resourceTypeId,
                                           java.lang.String logicalId)

Description copied from interface: ILogicalResourceIdentCache

Get the database logical_resourc_id for the given resource type and logicalId

Specified by:

getLogicalResourceId in interface ILogicalResourceIdentCache

Returns:

resolveReferenceValues

public void resolveReferenceValues(java.util.Collection<ResourceReferenceValueRec> values,
                                   java.util.List<ResourceReferenceValueRec> misses)

Description copied from interface: ILogicalResourceIdentCache

Lookup all the database values we have cached for the given collection. Put any objects with cache misses into the corresponding miss lists (so that we know which records we need to generate inserts for)

Specified by:

resolveReferenceValues in interface ILogicalResourceIdentCache

misses - the objects we couldn't find in the cache

addRecord

public void addRecord(LogicalResourceIdentKey key,
                      long id)

Description copied from interface: ILogicalResourceIdentCache

Add the LogicalResourceIdent key and id to the local cache

Specified by:

addRecord in interface ILogicalResourceIdentCache

reset

public void reset()

Description copied from interface: ILogicalResourceIdentCache

Clear the thread-local and shared caches (for test purposes)

Specified by:

reset in interface ILogicalResourceIdentCache

clearLocalMaps

public void clearLocalMaps()

Description copied from interface: ILogicalResourceIdentCache

Clear any thread-local cache maps (probably because a transaction was rolled back)

Specified by:

clearLocalMaps in interface ILogicalResourceIdentCache
