Examples with Handlers org.jdbi.v3.sqlobject.Handlers used on opensource projects

Example 1 with Handlers

use of org.jdbi.v3.sqlobject.Handlers in project jdbi by jdbi.

the class SqlObjectFactory method attach.

/**
 * Create a sql object of the specified type bound to this handle. Any state changes to the handle, or the sql
 * object, such as transaction status, closing it, etc, will apply to both the object and the handle.
 *
 * @param extensionType the type of sql object to create
 * @param handle the Handle instance to attach ths sql object to
 * @return the new sql object bound to this handle
 */
@Override
public <E> E attach(Class<E> extensionType, HandleSupplier handle) {
    Map<Method, Handler> handlers = methodHandlersFor(extensionType, handle.getConfig(Handlers.class), handle.getConfig(HandlerDecorators.class));
    ConfigRegistry instanceConfig = handle.getConfig().createCopy();
    for (Class<?> iface : extensionType.getInterfaces()) {
        forEachConfigurer(iface, (configurer, annotation) -> configurer.configureForType(instanceConfig, annotation, extensionType));
    }

    InvocationHandler invocationHandler = createInvocationHandler(extensionType, instanceConfig, handlers, handle);
    return extensionType.cast(Proxy.newProxyInstance(extensionType.getClassLoader(), new Class[] { extensionType }, invocationHandler));
}

Example 2 with Handlers

use of org.jdbi.v3.sqlobject.Handlers in project jdbi by jdbi.

the class SqlObjectFactory method methodHandlersFor.

    return handlersCache.computeIfAbsent(sqlObjectType, type -> {
        final Map<Method, Handler> handlers = new HashMap<>();

        handlers.putAll(handlerEntry((t, a, h) -> t == a[0], Object.class, "equals", Object.class));
        handlers.putAll(handlerEntry((t, a, h) -> System.identityHashCode(t), Object.class, "hashCode"));
        handlers.putAll(handlerEntry((t, a, h) -> h.getHandle(), SqlObject.class, "getHandle"));
        try {
            handlers.putAll(handlerEntry((t, a, h) -> null, sqlObjectType, "finalize"));
        }// optional implementation
         catch (IllegalStateException expected) {
        }
        for (Method method : sqlObjectType.getMethods()) {
