FamilyOperation

KIT · type · 类型合同

One of the four family mutations.

导入

TypeScript

import type { FamilyOperation } from '@jangts/agent-core/kits/family';

JavaScript

/** @typedef {import('@jangts/agent-core/kits/family').FamilyOperation} FamilyOperation */

其他公开入口：@jangts/agent-core/types、@jangts/agent-core/structs、@jangts/agent-core/kits、@jangts/agent-core/kits/family。

定义

type FamilyOperation = (typeof familyOperations)[number];

索引结构

字段	类型	必需	说明
[key: number]	string	必需	只读。索引项。

联合分支结构

使用示例

• Agent 分支：版本、合并与显式启用：在真实 CAS 存储上管理数据分支，候选版本经检查和授权后显式启用。

配置状态检查、来源验证和三方合并

配置 · Node.js

TypeScript

import { defineAgentFamily } from '@jangts/agent-core/kits/family';
import type { FamilyStore } from '@jangts/agent-core/kits/family';
import type { OperationContext } from '@jangts/agent-core';

type State = { goal: string; sourceRevision: string };
export function family<App>(store: FamilyStore<State>,
  authorize: (context: OperationContext<App>) => Promise<void>,
  verify: (state: State) => Promise<void>) {
  return defineAgentFamily<State, App>({
    store, maxVersions: 16, retentionMs: 7 * 86400000,
    isState: (value): value is State => !!value && typeof (value as State).goal === 'string'
      && typeof (value as State).sourceRevision === 'string',
    authorize: (_operation, _record, context) => authorize(context),
    validate: candidate => verify(candidate.state),
    async merge({ base, target, source }) {
      if (target.goal !== base.goal && source.goal !== base.goal && target.goal !== source.goal)
        return { conflicts: ['goal'] };
      return { value: target.goal === base.goal ? source : target, conflicts: [] };
    },
  });
}

JavaScript

import { defineAgentFamily } from '@jangts/agent-core/kits/family';
export function family(store, authorize, verify) {
    return defineAgentFamily({
        store, maxVersions: 16, retentionMs: 7 * 86400000,
        isState: (value) => !!value && typeof value.goal === 'string'
            && typeof value.sourceRevision === 'string',
        authorize: (_operation, _record, context) => authorize(context),
        validate: candidate => verify(candidate.state),
        async merge({ base, target, source }) {
            if (target.goal !== base.goal && source.goal !== base.goal && target.goal !== source.goal)
                return { conflicts: ['goal'] };
            return { value: target.goal === base.goal ? source : target, conflicts: [] };
        },
    });
}

显式启用已批准的候选版本

扩展 · Node.js

App 在真实审批后调用；promote 仍重新执行来源、授权、版本和 CAS 检查。

TypeScript

import type { AgentFamily } from '@jangts/agent-core/kits/family';
import type { OperationContext } from '@jangts/agent-core';

export async function activate<State, App>(family: AgentFamily<State, App>, id: string,
  candidateId: string, context: OperationContext<App>) {
  const record = await family.read(id, context);
  return family.promote({ id, revision: record.revision, candidateId,
    expectedActiveId: record.activeId }, context);
}

JavaScript

export async function activate(family, id, candidateId, context) {
    const record = await family.read(id, context);
    return family.promote({ id, revision: record.revision, candidateId,
        expectedActiveId: record.activeId }, context);
}
