public abstract class AbstractMTAsynchronouslyRefreshedCache<T>
extends org.alfresco.util.cache.AbstractAsynchronouslyRefreshedCache<T>
implements AsynchronouslyRefreshedCache<T>, org.springframework.beans.factory.InitializingBean

The base implementation for Multi-tenant asynchronously refreshed cache. Currently supports one value per tenant. Implementors just need to provide buildCache(String tennantId)

Method Detail

setTenantService

public void setTenantService(org.alfresco.repo.tenant.TenantService tenantService)

Parameters:

tenantService - the tenantService to set

get

public T get()

Description copied from interface: RefreshableCache

Get the cache. If there is no cache value this call will block. If the underlying cache is being refreshed, the old cache value will be returned until the refresh is complete.

Returns:

T

forceInChangesForThisUncommittedTransaction

public void forceInChangesForThisUncommittedTransaction()

refresh

public void refresh()

Description copied from interface: RefreshableCache

Refresh the cache asynchronously.

isUpToDate

public boolean isUpToDate()

Description copied from interface: AsynchronouslyRefreshedCache

Determine if the cache is up to date

Returns:

true if the cache is not currently refreshing itself

buildCache

protected abstract T buildCache(String tenantId)

Build the cache entry for the specific tenant. This method is called in a thread-safe manner i.e. it is only ever called by a single thread.

Specified by:

afterPropertiesSet

public void afterPropertiesSet()
                        throws Exception

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

Overrides:

Throws:

Exception
