NodeID is an identifier for a node in the address space of an OPC UA Server. The NodeID object encodes all different node id types.

func MustParseNodeID added in v0.2.0 

func MustParseNodeID(s string) *NodeID

MustParseNodeID returns a node id from a string definition if it is parseable by ParseNodeID. Otherwise, the function panics.

func NewByteStringNodeID 

func NewByteStringNodeID(ns uint16, id []byte) *NodeID

NewByteStringNodeID returns a new byte string node id.

func NewFourByteNodeID 

func NewFourByteNodeID(ns uint8, id uint16) *NodeID

func ParseNodeID 

func ParseNodeID(s string) (*NodeID, error)

ParseNodeID returns a node id from a string definition of the format 'ns=<namespace>;{s,i,b,g}=<identifier>'.

The 's=' prefix can be omitted for string node ids in namespace 0.

For numeric ids the smallest possible type which can store the namespace and id value is returned.

Namespace URIs are not supported since NodeID cannot store them. If you need to support namespace URIs use ParseExpandedNodeID.

func (*NodeID) IntID 

func (n *NodeID) IntID() uint32

IntID returns the identifier value if the type is TwoByte, FourByte or Numeric. For all other types IntID returns 0.

func (*NodeID) MarshalJSON added in v0.2.0 

func (n *NodeID) MarshalJSON() ([]byte, error)

func (*NodeID) Namespace 

func (n *NodeID) Namespace() uint16

func (n *NodeID) SetNamespace(v uint16) error

SetNamespace sets the namespace id. It returns an error if the id is not within the range of the node id type.

func (*NodeID) SetStringID 

func (n *NodeID) SetStringID(v string) error

SetStringID sets the identifier value for string, guid and opaque node ids. It returns an error for other types.

func (*NodeID) SetURIFlag 

func (n *NodeID) SetURIFlag()

SetURIFlag sets NamespaceURI flag in EncodingMask.

func (*NodeID) String 

func (n *NodeID) String() string

String returns the string representation of the NodeID in the format described by ParseNodeID.

func (*NodeID) StringID 

func (n *NodeID) StringID() string

StringID returns the string value of the identifier for String and GUID NodeIDs, and the base64 encoded value for Opaque types. For all other types StringID returns an empty string.

type TypeRegistry added in v0.1.3 

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

TypeRegistry provides a registry for Go types.

Each type is registered with a unique identifier which cannot be changed for the lifetime of the component.

Types can be registered multiple times under different identifiers.

The implementation is safe for concurrent use.

func NewTypeRegistry added in v0.1.3 

func NewTypeRegistry() *TypeRegistry

NewTypeRegistry returns a new type registry.

func (*TypeRegistry) Lookup added in v0.1.3 

func (r *TypeRegistry) Lookup(v interface{}) *NodeID

Lookup returns the id of the type of v or nil if the type is not registered.

If the type was registered multiple times the first registered id for this type is returned.

func (*TypeRegistry) New added in v0.1.3 

func (r *TypeRegistry) New(id *NodeID) interface{}

New returns a new instance of the type with the given id.

If the id is not known the function returns nil.

New panics if id is nil.

func (*TypeRegistry) Register added in v0.1.3 

func (r *TypeRegistry) Register(id *NodeID, v interface{}) error

Register adds a new type to the registry.

If the id is already registered as a different type the function returns an error.

Register panics if id is nil.
