Detailed Description

Represents a message with information for sender and receiver, and provides methods for converting between PDU and message content.

This class handles the mapping between string-formatted PDUs (Representation) and text messages with sender- and receiver information (Content). It offers constructors for creating Message objects from different types of inputs and provides methods to convert between a message's content and its PDU representation.

Note

The Message class inherits from Content<Message_content_t, String>, providing a specialized implementation for handling messages.

Constructors

• Message(): Default constructor, initializes an empty message.
• Message(bool boolean_expression): Constructs a message with default content (Sender: 0x0, Receiver: 0x0, Text: \0) if the boolean expression is true.
• Message(String* representation): Constructs a message from a string-formatted PDU.
• Message(Message_content_t* message_content): Constructs a message from Message_content_t, which holds the sender ID, receiver ID, and message text.

Methods

• String to_string(): Returns a string representation of the message.
• void rep_to_content(): Converts the byte-representation (PDU) to message content. This method is overridden from the base class Content.
• void content_to_rep(): Converts message content to byte-representation (PDU). This method is overridden from the base class Content.
