OutboundQueue class

A serialized, byte-bounded outbound send queue.

Messages are sent one at a time (each add waits for the previous send to complete), which both preserves ordering and provides a natural back-pressure point: when a consumer is slow, its onSend futures complete slowly and the queued byte count grows. If the queued (not-yet-sent) bytes would exceed maxBufferSize, add rejects with OutboundBufferOverflow instead of buffering without bound.

Constructors

OutboundQueue({required Future<void> onSend(List<int> data), required int maxBufferSize})
A serialized, byte-bounded outbound send queue.

Properties

The hash code for this object.

isClosed bool
Whether the queue has been closed (manually or by an overflow).

Bytes currently queued and waiting to be sent.

Methods

add(List<int> data) Future<void>
Enqueue data for sending.
close() → void
Close the queue. Subsequent add calls throw and queued (not-yet-sent) messages are dropped.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() String
A string representation of this object.

Operators

operator ==(Object other) bool
The equality operator.
