LazyMessagePayload class
A payload view that delays decoding until an application reads its values.
The view can retain encoded argument slices or one packed PPT payload while preserving the object that owns the underlying storage through anchor.
Constructors
-
LazyMessagePayload.encoded({Uint8List? transparentBinaryPayload, LazyPayloadEncoding? encoding, WampE2eeProvider? e2eeProvider, WampE2eeRuntimeContext? e2eeRuntimeContext, Uint8List? argumentsBytes, Uint8List? argumentsKeywordsBytes, PayloadListDecoder? argumentsDecoder, PayloadMapDecoder? argumentsKeywordsDecoder, List? arguments, Map<
String, dynamic> ? argumentsKeywords, Object? anchor}) -
Creates a view backed by separately encoded positional and keyword data.

LazyMessagePayload.materialized({Uint8List? transparentBinaryPayload, LazyPayloadEncoding? encoding, List? arguments, Map<
String, dynamic> ? argumentsKeywords, bool pptDecoded = false, WampE2eeProvider? e2eeProvider, WampE2eeRuntimeContext? e2eeRuntimeContext, Object? anchor}) -
Creates a view from already materialized positional and keyword values.
factory
- LazyMessagePayload.packed({Uint8List? transparentBinaryPayload, required LazyPayloadEncoding? encoding, required Uint8List packedPayloadBytes, required PackedPayloadDecoder packedPayloadDecoder, bool pptDecoded = true, WampE2eeProvider? e2eeProvider, WampE2eeRuntimeContext? e2eeRuntimeContext, Object? anchor})
-
Creates a view backed by one packed Payload Passthru Mode value.

Properties
- anchor → Object?
-
Keeps externally owned encoded storage alive for this view's lifetime.
final
- arguments → List?
-
Positional arguments, decoded on first access when necessary.
no setter
- argumentsBytes → Uint8List?
-
The encoded positional argument slice, when one was retained.
no setter
-
argumentsKeywords
→ Map<
String, dynamic> ? -
Keyword arguments, decoded on first access when necessary.
no setter
- argumentsKeywordsBytes → Uint8List?
-
The encoded keyword argument slice, when one was retained.
no setter
- e2eeProvider → WampE2eeProvider?
-
The provider used to decrypt a retained E2EE payload when required.
final
- e2eeRuntimeContext → WampE2eeRuntimeContext?
-
Runtime context associated with an encoded E2EE payload.
final
- encoding → LazyPayloadEncoding?
-
The serializer needed to decode the retained argument bytes.
final
- hasEncodedArguments → bool
-
Whether encoded positional arguments remain available without decoding.
no setter
- hasEncodedArgumentsKeywords → bool
-
Whether encoded keyword arguments remain available without decoding.
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- hasPackedPayloadBytes → bool
-
Whether this view retains one packed PPT payload.
no setter
- packedPayloadBytes → Uint8List?
-
The packed PPT payload bytes, when available.
no setter
- pptDecoded → bool
-
Whether any PPT or E2EE wrapper has already been removed.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- transparentBinaryPayload → Uint8List?
-
The transparent binary payload carried outside regular WAMP arguments.
final
Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toOwned(
) → LazyMessagePayload - Copies retained buffers and materialized WAMP lists, maps and binary values without forcing decoding. Providers, contexts and decoder callbacks remain shared; the external storage anchor is not retained.
-
toString(
) → String -
A string representation of this object.
inherited
-
withAnchor(
Object? anchor) → LazyMessagePayload -
Returns an equivalent view that retains
anchor. -
withE2eeProvider(
WampE2eeProvider? provider) → LazyMessagePayload -
Returns an equivalent view associated with
provider. -
withE2eeRuntimeContext(
WampE2eeRuntimeContext? runtimeContext) → LazyMessagePayload -
Returns an equivalent view associated with
runtimeContext.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
