Make new cores available for discovery

Parameters:

cc - the CoreContainer

coreDescriptors - CoreDescriptors to persist

persist

void persist(CoreContainer cc,
             CoreDescriptor... coreDescriptors)

Ensure that the core definitions from the passed in CoreDescriptors will persist across container restarts.

Parameters:

cc - the CoreContainer

coreDescriptors - CoreDescriptors to persist

delete

void delete(CoreContainer cc,
            CoreDescriptor... coreDescriptors)

Ensure that the core definitions from the passed in CoreDescriptors are not available for discovery

Parameters:

cc - the CoreContainer

coreDescriptors - CoreDescriptors of the cores to remove

rename

void rename(CoreContainer cc,
            CoreDescriptor oldCD,
            CoreDescriptor newCD)

Persist the new name of a renamed core

Parameters:

cc - the CoreContainer

oldCD - the CoreDescriptor of the core before renaming

newCD - the CoreDescriptor of the core after renaming

swap

void swap(CoreContainer cc,
          CoreDescriptor cd1,
          CoreDescriptor cd2)

Swap two core definitions

Parameters:

cc - the CoreContainer

discover

List<CoreDescriptor> discover(CoreContainer cc)

Load all the CoreDescriptors from persistence store

Parameters:

cc - the CoreContainer

Returns:

a list of all CoreDescriptors found

reload

CoreDescriptor reload(CoreDescriptor cd,
                      CoreContainer cc)

Reload a core descriptor.

Parameters:

cd - the old core descriptor

cc - the CoreContainer

Returns:

a new core descriptor

instantiate

static CoresLocator instantiate(NodeConfig nodeConfig)

Returns a new instance of CoresLocator, depending on provided config.

Parameters:

nodeConfig - Solr configuration.
