Constants

const ConfigID = ControllerID

ConfigID is the string used to identify this config object.

const ControllerID = "controllerbus/bus/api/1"

ControllerID identifies the API controller.

Variables

var (
	ErrInvalidLength        = fmt.Errorf("proto: negative length found during unmarshaling")
	ErrIntOverflow          = fmt.Errorf("proto: integer overflow")
	ErrUnexpectedEndOfGroup = fmt.Errorf("proto: unexpected end of group")
)

var Version = semver.MustParse("0.0.1")

Version is the API version.

Types

type Config

type Config struct {
	// ListenAddr is the address to listen on for connections.
	ListenAddr string `protobuf:"bytes,1,opt,name=listen_addr,json=listenAddr,proto3" json:"listen_addr,omitempty"`
	// BusApiConfig are options for controller bus api.
	BusApiConfig         *api.Config `protobuf:"bytes,2,opt,name=bus_api_config,json=busApiConfig,proto3" json:"bus_api_config,omitempty"`
	XXX_NoUnkeyedLiteral struct{}    `json:"-"`
	XXX_unrecognized     []byte      `json:"-"`
	XXX_sizecache        int32       `json:"-"`
}

Config configures the API.

func (*Config) Descriptor

func (*Config) Descriptor() ([]byte, []int)

func (*Config) EqualVT

func (this *Config) EqualVT(that *Config) bool

func (*Config) EqualsConfig

func (c *Config) EqualsConfig(other config.Config) bool

EqualsConfig checks if the other config is equal.

func (*Config) GetBusApiConfig

func (m *Config) GetBusApiConfig() *api.Config

func (*Config) GetConfigID

func (c *Config) GetConfigID() string

GetConfigID returns the unique string for this configuration type. This string is stored with the encoded config.

func (*Config) GetListenAddr

func (m *Config) GetListenAddr() string

func (*Config) MarshalToSizedBufferVT

func (m *Config) MarshalToSizedBufferVT(dAtA []byte) (int, error)

func (*Config) MarshalToVT

func (m *Config) MarshalToVT(dAtA []byte) (int, error)

func (*Config) MarshalVT

func (m *Config) MarshalVT() (dAtA []byte, err error)

func (*Config) ProtoMessage

func (*Config) ProtoMessage()

func (*Config) Reset

func (m *Config) Reset()

func (*Config) SizeVT

func (m *Config) SizeVT() (n int)

func (*Config) String

func (m *Config) String() string

func (*Config) UnmarshalVT

func (m *Config) UnmarshalVT(dAtA []byte) error

func (*Config) Validate

func (c *Config) Validate() error

Validate validates the configuration. This is a cursory validation to see if the values "look correct."

func (*Config) XXX_DiscardUnknown

func (m *Config) XXX_DiscardUnknown()

func (*Config) XXX_Marshal

func (m *Config) XXX_Marshal(b []byte, deterministic bool) ([]byte, error)

func (*Config) XXX_Merge

func (m *Config) XXX_Merge(src proto.Message)

func (*Config) XXX_Size

func (m *Config) XXX_Size() int

func (*Config) XXX_Unmarshal

func (m *Config) XXX_Unmarshal(b []byte) error

type Controller

type Controller struct {
	// contains filtered or unexported fields
}

Controller implements the API controller. The controller looks up the Node, acquires its identity, listens, and responds to incoming API calls.

func NewController

func NewController(
	le *logrus.Entry,
	listenAddr string,
	bus bus.Bus,
	conf *Config,
) *Controller

NewController constructs a new API controller.

func (*Controller) Close

func (c *Controller) Close() error

Close releases any resources used by the controller. Error indicates any issue encountered releasing.

func (*Controller) Execute

func (c *Controller) Execute(ctx context.Context) error

Execute executes the API controller and the listener. Returning nil ends execution. Returning an error triggers a retry with backoff.

func (*Controller) GetControllerInfo

func (c *Controller) GetControllerInfo() controller.Info

GetControllerInfo returns information about the controller.

func (*Controller) HandleDirective

func (c *Controller) HandleDirective(ctx context.Context, di directive.Instance) (directive.Resolver, error)

HandleDirective asks if the handler can resolve the directive. If it can, it returns a resolver. If not, returns nil. Any exceptional errors are returned for logging. It is safe to add a reference to the directive during this call.

type Factory

type Factory struct {
	// contains filtered or unexported fields
}

Factory constructs a API.

func NewFactory

func NewFactory(bus bus.Bus) *Factory

NewFactory builds a UDP transport factory.

func (*Factory) Construct

func (t *Factory) Construct(
	conf config.Config,
	opts controller.ConstructOpts,
) (controller.Controller, error)

Construct constructs the associated controller given configuration. The transport's identity (private key) comes from a GetNode lookup.

func (*Factory) ConstructConfig

func (t *Factory) ConstructConfig() config.Config

ConstructConfig constructs an instance of the controller configuration.

func (*Factory) GetConfigID

func (t *Factory) GetConfigID() string

GetConfigID returns the unique ID for the config.

func (*Factory) GetControllerID

func (t *Factory) GetControllerID() string

GetControllerID returns the unique ID for the controller.

func (*Factory) GetVersion

func (t *Factory) GetVersion() semver.Version

GetVersion returns the version of this controller.
