Glossary¶

• event payload: domain object (programming language dependent) that is associated with an event.

  Example(C++,pb,spread): an object ob type IplImage*

• wire type: Data type (programming language dependent?) of serialized representation of event payload

  Example(C++,pb,spread): unsigned char*

• wire format: Format (schema) of serialized representation of event payload

  Example(C++,pb,spread): specified by ImageMessage protocol buffer descriptor

• domain->wire converter: Mechanism that transforms event payloads into data of the wire type that has an interpretation w.r.t. the wire format. Uniquely identified by the triple
  1. domain type
  2. wire type
  3. wire format

     Example(C++,pb,spread): AbstractConverter<std::string>?

• wire->domain converter: Similar
• notification: Transport-specific message that contains
  • event meta-data
  • wire format
  • (wire type, wire format) representation of payload
    Note: does not contain domain type of event payload
