Classes, Fields and Messages

Classes have both fields and messages. Messages are either implicit or explicit where an implicit message is one of:

• a constructor (usually called "create");
• a destructor (usually called "destroy");
• "get_by_name_label";
• "get_by_uuid";
• "get_record";
• "get_all"; and
• "get_all_records".

Explicit messages include all the rest, more class-specific messages (e.g. "VM.start", "VM.clone")

Every field has at least one accessor depending both on its type and whether it is read-only or read-write. Accessors for a field named "X" would be a proper subset of:

• set_X: change the value of field X (only if it is read-write);
• get_X: retrieve the value of field X;
• add_X: add a key/value pair (for fields of type set);
• remove_X: remove a key (for fields of type set);
• add_to_X: add a key/value pair (for fields of type map); and
• remove_from_X: remove a key (for fields of type map).
