示例1: decodeExtensionObject
export function decodeExtensionObject(stream: BinaryStream): ExtensionObject | null {
const nodeId = decodeNodeId(stream);
const encodingType = stream.readUInt8();
if (encodingType === 0) {
return null;
}
const length = stream.readUInt32();
/* istanbul ignore next */
if (nodeId.value === 0 || encodingType === 0) {
return {} as ExtensionObject;
}
// let verify that decode will use the expected number of bytes
const streamLengthBefore = stream.length;
let object: any;
if (nodeId.namespace !== 0) {
// this is a extension object define in a other namespace
// we can only threat it as an opaque object for the time being
// the caller that may now more about the namespace Array and type
// definition will be able to turn the opaque object into a meaningful
// structure
// lets rewind before the length
stream.length -= 4;
object = new OpaqueStructure(nodeId, stream.readByteStream()!);
} else {
object = constructEmptyExtensionObject(nodeId);
/* istanbul ignore next */
if (object === null) {
// this object is unknown to us ..
stream.length += length;
object = {} as ExtensionObject;
} else {
try {
object.decode(stream);
} catch (err) {
debugLog("Cannot decode object ", err.message);
}
}
}
if (streamLengthBefore + length !== stream.length) {
// this may happen if the server or client do have a different OPCUA version
// for instance SubscriptionDiagnostics structure has been changed between OPCUA version 1.01 and 1.04
// causing 2 extra member to be added.
debugLog(chalk.bgWhiteBright.red("========================================="));
// tslint:disable-next-line:no-console
console.warn("WARNING => Extension object decoding error on ",
object.constructor.name, " expected size was", length,
"but only this amount of bytes have been read :", stream.length - streamLengthBefore);
stream.length = streamLengthBefore + length;
}
return object;
}示例2: decodeByteString
export function decodeByteString(stream: BinaryStream): ByteString {
return stream.readByteStream() as ByteString;
}
