unpackIntoHelper<T extends GeneratedMessage> function
void
unpackIntoHelper<T extends GeneratedMessage>(
- List<
int> value, - T instance,
- String typeUrl, {
- ExtensionRegistry extensionRegistry = ExtensionRegistry.EMPTY,
Unpacks the message in value
into instance
.
Throws a InvalidProtocolBufferException if typeUrl
does not correspond
with the type of instance
.
This is a helper method for Any.unpackInto
.
Implementation
void unpackIntoHelper<T extends GeneratedMessage>(
List<int> value, T instance, String typeUrl,
{ExtensionRegistry extensionRegistry = ExtensionRegistry.EMPTY}) {
// From "google/protobuf/any.proto":
//
// The pack methods provided by protobuf library will by default use
// 'type.googleapis.com/full.type.name' as the type URL and the unpack
// methods only use the fully qualified type name after the last '/'
// in the type URL, for example "foo.bar.com/x/y.z" will yield type
// name "y.z".
if (!canUnpackIntoHelper(instance, typeUrl)) {
var typeName = instance.info_.qualifiedMessageName;
throw InvalidProtocolBufferException.wrongAnyMessage(
_typeNameFromUrl(typeUrl), typeName);
}
instance.mergeFromBuffer(value, extensionRegistry);
