Types ¶
type Actor ¶
type Actor interface {
// Receive is called when Actor receives a new Message.
// Returns a new Actor state and/or error.
Receive(message Message) (Actor, error)
}
Actor is an entity that processes messages, sends messages to other actors and stores some state.
type Constructor ¶
Constructor is a procedure that creates a new Actor. It is called when Actor is created, before receiving any Messages. `state` sets the initial actor state. If `limit` is > 0 it sets the maximum size of the mailbox (only for regular, not stashed, not priority messages).
type System ¶
type System interface {
// Spawn creates a new Actor and returns it's Pid.
Spawn(constructor Constructor) Pid
// Send sends a Message to the Actor with a given Pid. InvalidPid is
// returned if actor with a given Pid doesn't exist or was terminated.
// MailboxFull is returned if acrtor's mailbox is full.
Send(pid Pid, message Message) error
// SendPriority sends a priority Message to the Actor with a given Pid.
// Priority messages are processed before any other messages. InvalidPid is
// returned if actor with a given Pid doesn't exist or was terminated.
SendPriority(pid Pid, message Message) error
// AwaitTermination returns when all spawned Actors terminate.
AwaitTermination()
}
System is a class responsible for creating, scheduling and otherwise controlling actors.
