定义

interface PreparedSessionTransport

字段结构

字段	类型	必需	说明
options	Pick<ModelOptions, "functions" | "json" | "toolChoice" | "parallelToolCalls" | "temperature">	必需	只读。见类型定义及调用场景。
schemaChars	number	必需	只读。见类型定义及调用场景。
instruction	string	必需	只读。见类型定义及调用场景。
createResponse	() => ModelResponseCollector<ResolvedSessionResult>	必需	见类型定义及调用场景。

成员目录

成员	用途
createResponse	完整输入输出见下方重载。

成员详情

createResponse

PreparedSessionTransport.createResponse(): ModelResponseCollector<ResolvedSessionResult>

无调用参数。

返回： ModelResponseCollector<ResolvedSessionResult>。

返回值结构

字段	类型	必需	说明
call	{ id: string; name: string; argumentChars: number; } | undefined	可省略	只读。Native function call that carried the selection, when the response used one.
calls	readonly { id: string; name: string; argumentChars: number; toolId?: string; }[] | undefined	可省略	只读。All native calls carried by a session response; omitted by single-selection collectors.
outputChars	number	必需	只读。Output characters accumulated so far, for output-budget accounting.
push	(part: ModelPart) => void	必需	Appends one streamed part; parts arrive in provider order.
finish	() => ResolvedSessionResult	必需	Finalizes the response. Throws when the accumulated content is not a valid selection.

使用示例

• 模型传输与阶段投影：从 Tool 定义生成封存目录与阶段投影，原生函数和 JSON 适配复用同一 Tool 合同。
• Support：推荐用法的聚合入口：Support 聚合推荐的构造、策略与同源配置生成；Core 运行不依赖这个命名空间。

创建具名文本传输

入门 · Node.js

TypeScript

import { ModelRunner, Support } from '@jangts/agent-core';
const text = Support.createTextTransport({ id: 'brief', options: { temperature: 0.2 } });
const runner = new ModelRunner({ provider: { async *stream() { yield '服务正常'; } }, transports: [text] });
console.log((await runner.invoke({ input: '简答服务状态', transport: text })).value);

JavaScript

import { ModelRunner, Support } from '@jangts/agent-core';
const text = Support.createTextTransport({ id: 'brief', options: { temperature: 0.2 } });
const runner = new ModelRunner({ provider: { async *stream() { yield '服务正常'; } }, transports: [text] });
console.log((await runner.invoke({ input: '简答服务状态', transport: text })).value);

从同源 Tool 生成两个阶段的传输

配置 · Node.js

TypeScript

import { Support } from '@jangts/agent-core';
const inputSchema = Support.defineSchema({
  jsonSchema: { type: 'object', properties: {}, additionalProperties: false },
  parse(value: unknown) {
    if (!value || typeof value !== 'object' || Array.isArray(value) || Object.keys(value).length) throw new TypeError('需要空对象');
    return {};
  },
});
const tools = Support.defineModelTools([
  { id: 'greet', description: '问候', inputSchema, resolve: () => 'greet' },
  { id: 'status', description: '状态查询', inputSchema, resolve: () => 'status' },
]);
const transport = Support.createStageModelTransport({ id: 'intent', tools,
  stages: [{ id: 'recognize', toolIds: ['greet', 'status'] }, { id: 'status-only', toolIds: ['status'] }],
});
console.log(transport.prepare('status-only').schemaChars);

JavaScript

import { Support } from '@jangts/agent-core';
const inputSchema = Support.defineSchema({
    jsonSchema: { type: 'object', properties: {}, additionalProperties: false },
    parse(value) {
        if (!value || typeof value !== 'object' || Array.isArray(value) || Object.keys(value).length)
            throw new TypeError('需要空对象');
        return {};
    },
});
const tools = Support.defineModelTools([
    { id: 'greet', description: '问候', inputSchema, resolve: () => 'greet' },
    { id: 'status', description: '状态查询', inputSchema, resolve: () => 'status' },
]);
const transport = Support.createStageModelTransport({ id: 'intent', tools,
    stages: [{ id: 'recognize', toolIds: ['greet', 'status'] }, { id: 'status-only', toolIds: ['status'] }],
});
console.log(transport.prepare('status-only').schemaChars);
