Package io.kroxylicious.proxy.bootstrap

Class RouterChainFactory

java.lang.Object

io.kroxylicious.proxy.bootstrap.RouterChainFactory

All Implemented Interfaces:

AutoCloseable

public class RouterChainFactory
extends Object
implements AutoCloseable

Abstracts the creation of router instances, hiding the configuration required for instantiation at the point at which instances are created.

Each virtual cluster that references a router gets its own initialisation of that router's factory, so shared state (e.g. caches, metrics) is per-virtual-cluster.

RouterChainFactory

public RouterChainFactory(PluginFactoryRegistry pfr,
 List<VirtualCluster> virtualClusters,
 @Nullable
 List<RouterDefinition> routerDefinitions)

Method Details

forVirtualCluster

public static RouterChainFactory forVirtualCluster(PluginFactoryRegistry pfr,
 VirtualCluster vc,
 @Nullable
 Map<String,RouterDefinition> routersByName)

Creates a RouterChainFactory for a single virtual cluster. The factory initialises only the routers reachable from vc's router graph.

Parameters:

pfr - the plugin factory registry

vc - the virtual cluster whose router graph to initialise

routersByName - all router definitions by name (the graph may reference any of them)

Returns:

a new factory whose lifetime should match that of the virtual cluster

createRouter

public io.kroxylicious.proxy.router.Router createRouter(String routerName,
 String virtualClusterName)

Creates a new router instance for the given router name and virtual cluster.

Parameters:

routerName - the name of the router definition

virtualClusterName - the name of the virtual cluster

Returns:

the created router instance
