SemanticsWireDecoder class final

Client side: replays the encoder's frames, holding the flat node state and rebuilding a SemanticTree after each. One instance per session.

Constructors

SemanticsWireDecoder({int maxWirePayloadLength = maxRemoteDocumentFramePayloadLength})

changedIds → List<String>: Node ids whose serialized form changed in the most recently applied frame (every id on a full frame). The wire diff already carries exactly this, so surfacing it lets a consumer push a delta instead of the whole tree.
no setter
contentReplacements → Map<SemanticNodeId, SemanticNode>?: The nodes the most recently applied frame rebuilt, when it changed only the content of nodes already in the tree: those nodes and their ancestors, by id. A consumer can advance a SemanticsOwner with updateRetainedNodes instead of diffing the whole tree. Null after a full frame or a structural patch.
no setter
hashCode → int: The hash code for this object.
no setterinherited
isPrimed → bool: Whether a full frame has been applied (so patches have a base to land on).
no setter
maxWirePayloadLength → int: Maximum accepted frame and equivalent retained FULL payload bytes.
final
removedIds → List<String>: Node ids removed by the most recently applied frame (empty on a full frame, which replaces the whole tree).
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
wasFull → bool: Whether the most recently applied frame was a full (resync) frame — a consumer should treat changedIds as "re-read everything".
no setter

apply(List<int> bytes) → SemanticTree?: Applies one wire payload and returns the reconstructed tree, or null if the payload is malformed or a patch arrives before any full frame (a desync the caller should ignore, keeping the last good tree).
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.
