Examples of com.cloud.agent.transport.Request

com.cloud.agent.transport.Request
Request is a simple wrapper around command and answer to add sequencing, versioning, and flags. Note that the version here represents the changes in the over the wire protocol. For example, if we decide to not use Gson. It does not version the changes in the actual commands. That's expected to be done by adding new classes to the command and answer list. A request looks as follows: 1. Version - 1 byte; 2. Flags - 3 bytes; 3. Sequence - 8 bytes; 4. Length - 4 bytes; 5. ManagementServerId - 8 bytes; 6. AgentId - 8 bytes; 7. Data Package.
