Functions ¶
func ParseInstanceAndService ¶
ParseInstanceAndService parses one string, which describes a service and split it up into instance name and service name
func ServiceObserver ¶
func ServiceObserver(serviceNamePattern string, serviceAdded func(ServiceInfo) error, serviceRemoved func(ServiceInfo) error) error
ServiceObserver watches for added or removed services whose serviceTypes are matching the serviceNamePattern serviceNamePattern is compared as a glob pattern, i.e. if you want to observe service types beginning with "_io4edge", specify "_io4edge.*"; if you want to observe all services, specify "*".
serviceObserver runs in a loop until one of the callbacks returns an error. serviceAdded and serviceRemoved are called when an instance of an observed service type is added or removed.
Types ¶
type FuncInfoDefault ¶
type FuncInfoDefault struct {
// contains filtered or unexported fields
}
FuncInfoDefault provides the default FunctionInfo implementation
func NewFuncInfoDefault ¶
func NewFuncInfoDefault(address string) *FuncInfoDefault
NewFuncInfoDefault creates a new FuncInfoDefault object with no aux port
func NewFuncInfoDefaultWithAuxPort ¶
func NewFuncInfoDefaultWithAuxPort(address string, auxPort int, auxProtocol string, auxSchemaID string) *FuncInfoDefault
NewFuncInfoDefaultWithAuxPort creates a new FuncInfoDefault object with an aux port
func (*FuncInfoDefault) AuxPort ¶
func (f *FuncInfoDefault) AuxPort() (string, int, error)
AuxPort gives the caller the auxport value of the service protocol and port
func (*FuncInfoDefault) AuxSchemaID ¶
func (f *FuncInfoDefault) AuxSchemaID() (string, error)
AuxSchemaID gives the caller the auxschema value of the service
func (*FuncInfoDefault) FuncClass ¶
func (f *FuncInfoDefault) FuncClass() (string, error)
FuncClass gives the caller the funcclass value of the service
func (*FuncInfoDefault) NetAddress ¶
func (f *FuncInfoDefault) NetAddress() (string, int, error)
NetAddress gives the caller the ip address and port of the service
func (*FuncInfoDefault) Security ¶
func (f *FuncInfoDefault) Security() (string, error)
Security gives the caller the security value of the service
type ServiceInfo ¶
type ServiceInfo struct {
// contains filtered or unexported fields
}
ServiceInfo stores the avahi service struct of a service to make information about the service available through getter functions
func GetServiceInfo ¶
func GetServiceInfo(instanceName string, serviceName string, timeout time.Duration) (*ServiceInfo, error)
GetServiceInfo creates a new avahi server if necessary and starts a new service observer instance if no one is already running for the given mdns service name. If a service with the correct service address (consisting of <instance_name>.<service_name>.<protocol>) is found within the specified timeout, a service info object is returned. The instanceName should contain the instance name of the service address The serviceName should contain the service name of the service address together with the protocol The timeout specifies the time to wait for the service to show up
func (*ServiceInfo) AuxPort ¶
func (svcInf *ServiceInfo) AuxPort() (string, int, error)
AuxPort gives the caller the auxport value of the service protocol and port
func (*ServiceInfo) AuxSchemaID ¶
func (svcInf *ServiceInfo) AuxSchemaID() (string, error)
AuxSchemaID gives the caller the auxschema value of the service
func (*ServiceInfo) FuncClass ¶
func (svcInf *ServiceInfo) FuncClass() (string, error)
FuncClass gives the caller the funcclass value of the service
func (*ServiceInfo) GetIPAddressPort ¶
func (svcInf *ServiceInfo) GetIPAddressPort() string
GetIPAddressPort gets the ip address and port from the given service info object. It passes the caller the ip address and the port separated by ":" together in a string.
func (*ServiceInfo) GetInstanceName ¶
func (svcInf *ServiceInfo) GetInstanceName() string
GetInstanceName gets the instance name of the given service info object.
func (*ServiceInfo) GetServiceType ¶
func (svcInf *ServiceInfo) GetServiceType() string
GetServiceType gets the service type of the given service info object
func (*ServiceInfo) NetAddress ¶
func (svcInf *ServiceInfo) NetAddress() (string, int, error)
NetAddress gives the caller the ip address and port of the service
func (*ServiceInfo) Security ¶
func (svcInf *ServiceInfo) Security() (string, error)
Security gives the caller the security value of the service
