class documentation

class DictionaryEntry(ABC):

Known subclasses: server.ua_dictionary_entry.IrdiDictionaryEntry, server.ua_dictionary_entry.UriDictionaryEntry

Abstract OPC UA dictionary entry (OPC 10000-19).

Subclasses define the identifier format by setting the class variables and implementing _validate. Instances are immutable and validated on creation.

Method	`__post_init__`	Validate `semantic_id` via `_validate`.
Class Variable	`name`	Optional human-readable name; used as OPC UA display name.
Class Variable	`semantic_id`	Identifier defining the meaning (semantic); used as OPC UA browse name.
Class Variable	`ua_namespace_uri`	Namespace URI of the dictionary; instances of this entry type live in this namespace.
Class Variable	`ua_type_node_id`	Node ID of the OPC UA type representing this entry type.
Method	`_validate`	Check `semantic_id` against the entry type's format.
