transientCores

protected final com.github.benmanes.caffeine.cache.Cache<String,SolrCore> transientCores

Deprecated.

"Lazily loaded" cores cache with limited size. When the max size is reached, the least accessed core is evicted to make room for a new core.

transientDescriptors

Deprecated.

Method Detail

close

public void close()

Deprecated.

Description copied from class: TransientSolrCoreCache

Called in order to free resources.

Overrides:

close in class TransientSolrCoreCache

addCore

public SolrCore addCore(String name,
                        SolrCore core)

Deprecated.

Description copied from class: TransientSolrCoreCache

Adds the newly-opened core to the list of open cores.

Specified by:

addCore in class TransientSolrCoreCache

getAllCoreNames

public Set<String> getAllCoreNames()

Deprecated.

Description copied from class: TransientSolrCoreCache

Returns the names of all possible cores, whether they are currently loaded or not.

Specified by:

getAllCoreNames in class TransientSolrCoreCache

getLoadedCoreNames

public Set<String> getLoadedCoreNames()

Deprecated.

Description copied from class: TransientSolrCoreCache

Returns the names of all currently loaded cores.

Specified by:

getLoadedCoreNames in class TransientSolrCoreCache

removeCore

public SolrCore removeCore(String name)

Deprecated.

Description copied from class: TransientSolrCoreCache

Removes a core from the internal structures, presumably it being closed. If the core is re-opened, it will be re-added by CoreContainer.

Specified by:

removeCore in class TransientSolrCoreCache

getCore

public SolrCore getCore(String name)

Deprecated.

Description copied from class: TransientSolrCoreCache

Gets the core associated with the name. Returns null if there is none.

Specified by:

containsCore

public boolean containsCore(String name)

Deprecated.

Description copied from class: TransientSolrCoreCache

Returns whether the cache contains the named core.

Specified by:

containsCore in class TransientSolrCoreCache

addTransientDescriptor

public void addTransientDescriptor(String rawName,
                                   CoreDescriptor cd)

Deprecated.

Description copied from class: TransientSolrCoreCache

Adds a new CoreDescriptor. This method will only be called during core discovery at startup.

Specified by:

addTransientDescriptor in class TransientSolrCoreCache

getTransientDescriptor

public CoreDescriptor getTransientDescriptor(String name)

Deprecated.

Description copied from class: TransientSolrCoreCache

Gets the CoreDescriptor for a transient core (loaded or unloaded). This method is used when opening cores and the like. If you want to change a core's descriptor, override this method and return the current core descriptor.

Deprecated.

Description copied from class: TransientSolrCoreCache

Removes a CoreDescriptor from the list of transient cores descriptors.

Specified by:

removeTransientDescriptor in class TransientSolrCoreCache

getStatus

public int getStatus(String coreName)

Deprecated.

Description copied from class: TransientSolrCoreCache

Gets a custom status for the given core name. Allows custom implementations to communicate arbitrary information as necessary.

Specified by:
