示例1: constructEventFilter
export function constructEventFilter(
arrayOfNames: string[] | string,
conditionTypes?: NodeId[] | NodeId
): EventFilter {
if (!_.isArray(arrayOfNames)) {
return constructEventFilter([arrayOfNames], conditionTypes);
}
if (conditionTypes && !_.isArray(conditionTypes)) {
return constructEventFilter(arrayOfNames, [conditionTypes]);
}
if (!(arrayOfNames instanceof Array)) {
throw new Error("internal error");
}
// replace "string" element in the form A.B.C into [ "A","B","C"]
const arrayOfNames2 = arrayOfNames.map((path) => {
if (typeof path !== "string") {
return path;
}
return path.split(".");
});
const arrayOfNames3 = arrayOfNames2.map((path) => {
if (_.isArray(path)) {
return path.map(stringToQualifiedName);
}
return path;
});
// replace "string" elements in arrayOfName with QualifiedName in namespace 0
const arrayOfNames4 = arrayOfNames3.map((s) => {
return (typeof s === "string") ? stringToQualifiedName(s) : s;
});
// construct browse paths array
const browsePaths = arrayOfNames4.map((s) => {
return _.isArray(s) ? s : [s];
});
// Part 4 page 127:
// In some cases the same BrowsePath will apply to multiple EventTypes. If the Client specifies the BaseEventType
// in the SimpleAttributeOperand then the Server shall evaluate the BrowsePath without considering the Type.
// [..]
// The SimpleAttributeOperand structure allows the Client to specify any Attribute, however, the Server is only
// required to support the Value Attribute for Variable Nodes and the NodeId Attribute for Object Nodes.
// That said, profiles defined in Part 7 may make support for additional Attributes mandatory.
let selectClauses = browsePaths.map((browsePath) => {

indexRange: undefined, // NumericRange

const extraSelectClauses = conditionTypes.map((nodeId) => {
return new SimpleAttributeOperand({
attributeId: AttributeIds.NodeId,
browsePath: undefined,
indexRange: undefined, // NumericRange
typeDefinitionId: nodeId // conditionType for instance
});
});
