class ServiceDirectory

Create an directory of services backed by given |directory|.

Requests for services are routed to entries in this directory.

The directory is expected to implement the |fuchsia.io.Directory| protocol.

Create an directory of services from this component's namespace.

Uses the "/svc" entry in the namespace as the backing directory for the

returned directory of services.

Rather than creating a new |ServiceDirectory| consider passing |svc()| from

your |ComponentContext| around as that makes your code unit testable and

consumes one less kernel handle.

Create a directory of services and return a request for an implementation

of the underlying directory in |out_request|.

Useful when creating components.

ServiceDirectory objects cannot be copied.

ServiceDirectory objects can be moved.

Connect to an interface in the directory.

The interface name and the channel must be supplied explicitly.

Returns whether the request was successfully sent to the remote directory

backing this service bundle.

# Errors

ZX_ERR_UNAVAILABLE: The directory backing this service bundle is invalid.

ZX_ERR_ACCESS_DENIED: This service bundle has insufficient rights to

connect to services.

# Example

```

zx::channel controller, request;

zx_status_t status = zx::channel::create(0,

&controller

,

&request

);

if (status != ZX_OK) {

[...]

}

directory.Connect("fuchsia.foo.Controller", std::move(request));

```

Clone underlying directory channel.

This overload for |CloneHandle| discards the status of the underlying

operation. Callers that wish to receive that status should use

other overload that returns a |zx_status_t|.

Clone underlying directory channel.

Returns whether the request was successfully sent to the remote directory

backing this service bundle.

# Errors

ZX_ERR_UNAVAILABLE: The directory backing this service bundle is invalid.

Other transport and application-level errors associated with

|fuchsia.io.Node/Clone|.

# Example

```

fuchsia::io::DirectoryPtr dir;

directory.CloneHandle(dir.NewRequest());

```

Connect to an interface in the directory.

The discovery name of the interface is inferred from the C++ type of the

interface. Callers can supply an interface name explicitly to override

the default name.

This overload for |Connect| discards the status of the underlying

connection operation. Callers that wish to receive that status should use

one of the other overloads that returns a |zx_status_t|.

# Example

```

auto controller = directory.Connect

<fuchsia

::foo::Controller>();

```

Connect to an interface in the directory.

The discovery name of the interface is inferred from the C++ type of the

interface request. Callers can supply an interface name explicitly to

override the default name.

Returns whether the request was successfully sent to the remote directory

backing this service bundle.

# Errors

ZX_ERR_UNAVAILABLE: The directory backing this service bundle is invalid.

ZX_ERR_ACCESS_DENIED: This service bundle has insufficient rights to

connect to services.

# Example

```

fuchsia::foo::ControllerPtr controller;

directory.Connect(controller.NewRequest());

```
