# CordaPluginRegistry

`abstract class CordaPluginRegistry`

Implement this interface on a class advertised in a META-INF/services/net.corda.core.node.CordaPluginRegistry file to extend a Corda node with additional application services.

### Constructors

<init> | `CordaPluginRegistry()` Implement this interface on a class advertised in a META-INF/services/net.corda.core.node.CordaPluginRegistry file to extend a Corda node with additional application services.

### Properties

requiredFlows | `open val requiredFlows: Map<String, Set<String>>` A Map with an entry for each consumed flow used by the webAPIs. The key of each map entry should contain the FlowLogic class name. The associated map values are the union of all concrete class names passed to the flow constructor. Standard java.lang.* and kotlin.* types do not need to be included explicitly. This is used to extend the white listed flows that can be initiated from the ServiceHub invokeFlowAsync method.
servicePlugins | `open val servicePlugins: List<Class<*>>` List of additional long lived services to be hosted within the node. They are expected to have a single parameter constructor that takes a PluginServiceHub as input. The PluginServiceHub will be fully constructed before the plugin service is created and will allow access to the flow factory and flow initiation entry points there.
staticServeDirs | `open val staticServeDirs: Map<String, String>` Map of static serving endpoints to the matching resource directory. All endpoints will be prefixed with "/web" and postfixed with "\*. Resource directories can be either on disk directories (especially when debugging) in the form "a/b/c". Serving from a JAR can be specified with: javaClass.getResource("<folder-in-jar>").toExternalForm()
webApis | `open val webApis: List<Class<*>>` List of JAX-RS classes inside the contract jar. They are expected to have a single parameter constructor that takes a ServiceHub as input. These are listed as Class<*>, because in the future they will be instantiated inside a ClassLoader so that Cordapp code can be loaded dynamically.

### Functions

registerRPCKryoTypes | `open fun registerRPCKryoTypes(kryo: <ERROR CLASS>): Boolean` Optionally register types with Kryo for use over RPC, as we lock down the types that can be serialised in this particular use case. For example, if you add an RPC interface that carries some contract states back and forth, you need to register those classes here using the register method on Kryo.
