ServiceCallContext - immutable user parameter map that will be implicitly passed to the service (and interceptor) on every method call.

ServiceCallInterceptor - intercepts service method calls.

Code Block

linenumbers	true

public interface ServiceCallInterceptor extends Serializable {
    // Called BEFORE the service method is executed.
    public default void onInvoke(ServiceInterceptorContext ctx) throws ServiceInterceptException {
        // No-op.
    }

    // Called AFTER the service method is executed.
    public default void onComplete(@Nullable Object res, ServiceInterceptorContext ctx) throws ServiceInterceptException {
        // No-op.
    }

    // Called when onInvoke, onComplete or service method throws an exception.
    public default void onError(Throwable err, ServiceInterceptorContext ctx) {
        // No-op.
    }
}

ServiceInterceptorContext - extended mutable version of caller context (interceptor obtains method call parameters from it and can use it to update the caller context).

Code Block

language	java
theme	RDark
title	ServiceInterceptorContext.java
linenumbers	true
collapse	true

public interface ServiceInterceptorContext extends ServiceCallContext {
    public String method();

    public @Nullable Object[] arguments();

    public void attribute(String name, String val);

    public void binaryAttribute(String name, byte[] val);
}

ServiceInterceptException - unchecked exception that is used to highlight the exception that occurred during method interception (not execution).
