Study Notes
Message Formats in SSD
- Messages in SSD consist of a message name followed by parameters (in parentheses)
- Names begin with a lowercase letter
- No spaces in names; use uppercase letters to separate words
- Names in parameters are separated by commas
- Empty parentheses () are used if no parameters
Outgoing Messages (System Outputs)
- System outputs are responses to complete an event
- Messages from the system to another system require action and a reply
- Every output is derived from input and stored data
Message Notation for SSD
[true/false condition] return-value := message-name (parameter-list)*indicates repeating or looping messages[]indicates a true/false condition (only tests the message)- Message name is verb-noun describing a service
- Parameter list (in/without parentheses) shows data passed with the message
- Return value (like
:) describes data returned to the original sender
