MQTTPath

The MQTTPath class is responsible for constructing and managing MQTT topic paths based on device and owner credentials. It ensures that MQTT topics are organized, secure, and adhere to a consistent naming convention. By centralizing the logic for topic path construction, MQTTPath simplifies the management of device-specific, group-specific, and public MQTT topics.

Methods:

• MQTTPath(const Credentials &credentials) Constructs an MQTTPath instance using the provided device credentials.

• const String& getDeviceId() const Retrieves the unique identifier of the device.

• const String& getOwnerId() const Retrieves the unique identifier of the device owner.

• String buildDevicePath(const String &topic) const Constructs a device-specific MQTT topic path by appending the provided subtopic to the base device path.

• String buildGroupPath(const String& groupId, const String &topic) const Constructs a group-specific MQTT topic path by incorporating the group identifier and the provided subtopic.

• String buildPublicPath(const String &topic) const Constructs a public MQTT topic path by appending the provided topic to the public prefix.

• const Credentials *getCredentials() const Retrieves the associated Credentials object.

Member Variables:

• const String mPrefix Stores the base prefix used for constructing MQTT topic paths, ensuring a standardized topic structure across the system.

• const Credentials *mpCredentials Pointer to the Credentials object containing device and owner identifiers, used for building secure and organized topic paths.
