IpcMessage class sealed

A length-prefixed, tagged Snapshot, Delta, CrdtSync, or reliable-sync control frame (ResyncRequest / OutboxAck) (protocol.md § IPC). The CrdtSync variant carries multi-writer plane traffic alongside the single-producer mirror; the control frames ride the same framed, tagged plane in reverse (receiver → sender) for reliable sync (#lzsync).

Properties

crdtSync → CrdtSync?

The CrdtSync if this is one, otherwise null.

no setter

delta → Delta?

The Delta if this is one, otherwise null.

no setter

hashCode → int

The hash code for this object.

no setter, inherited

isControl → bool

Whether this is a reliable-sync reverse-channel control frame (ResyncRequest / OutboxAck) — no node content, so permission filtering and blob spilling are the identity on it. Mirrors IpcMessage::is_control.

isCrdtSync → bool

isResyncRequest → bool

isSnapshot → bool

no setter

outboxAck → OutboxAck?

The OutboxAck if this is one, otherwise null.

no setter

resyncRequest → ResyncRequest?

The ResyncRequest if this is one, otherwise null.

no setter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

snapshot → Snapshot?

The Snapshot if this is one, otherwise null.

no setter

Methods

encodeJson() → Uint8List

UTF-8 JSON bytes of toWire.

encodeJsonStreaming() → Uint8List

Streaming equivalent of encodeJson (#lzdartstreamingjson): builds the JSON via writeJson into a StringBuffer instead of jsonEncode(toWire()), so the intermediate Map<String, Object> (and the inner List/Map allocations for the batch variants) is never materialized.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

toWire() → Object

The externally-tagged wire shape.

writeJson(StringSink sink) → void

Streaming JSON encoder (#lzdartstreamingjson): writes the canonical JSON for this IpcMessage directly into sink, avoiding the intermediate Map<String, Object> that toWire would produce and (for the Snapshot / Delta / CrdtSync variants) recursing into the payload's own writeJson so the per-batch allocations are eliminated too. Byte-identical to jsonEncode(toWire()).

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

decodeJson(Object data) → IpcMessage

Decode UTF-8 JSON bytes (or a JSON string) into an IpcMessage.

ofDelta(Delta delta) → IpcMessage

ofOutboxAck(OutboxAck ack) → IpcMessage

ofResyncRequest(ResyncRequest request) → IpcMessage

ofSnapshot(Snapshot snapshot) → IpcMessage
