Definition

interface ProtocolCheck<Value, Args>

Type parameters

Type parameter	Constraint	Default type
Value	—	—
Args	unknown[]	—

Field structure

Field	Type	Required	Description
when	((value: Value, ...args: Args) => boolean) | undefined	Optional	Read-only. Runs the check only when it returns true; must be synchronous.
occur	ProtocolPredicate<Value, Args> | readonly ProtocolPredicate<Value, Args>[]	Required	Read-only. Failing predicate or ordered OR-list; evaluation stops at the first failure.
error	ProtocolReason<Value, Args> | undefined	Optional	Read-only. Rejection wording; omitted means a default TypeError.
tags	readonly string[] | undefined	Optional	Read-only. Diagnostic tags attached to the rejection.

Examples

• Interaction: declare commands and bind local handlers: The fields, purpose, selector, checks, and handler of a command come from one declaration; the model cannot add executable handlers.

First define one explanatory command and validate it

Beginner · Node.js

TypeScript

import { Interaction } from '@jangts/agent-core/kits/interaction';
const protocol = Interaction.define({
  commandField: 'type', commands: {
    reply: { category: 'presentation', description: '展示已确认说明', fields: { text: { required: true, jsonSchema: { type: 'string' } } },
      checks: [{ occur: value => typeof value.text !== 'string', error: 'text 必须是字符串' }] },
  },
});
console.log(protocol.receive({ type: 'reply', text: '普通对象也能实现接口。' }));
console.log(protocol.modelJsonSchema);

JavaScript

import { Interaction } from '@jangts/agent-core/kits/interaction';
const protocol = Interaction.define({
    commandField: 'type', commands: {
        reply: { category: 'presentation', description: '展示已确认说明', fields: { text: { required: true, jsonSchema: { type: 'string' } } },
            checks: [{ occur: value => typeof value.text !== 'string', error: 'text 必须是字符串' }] },
    },
});
console.log(protocol.receive({ type: 'reply', text: '普通对象也能实现接口。' }));
console.log(protocol.modelJsonSchema);

Keep the same protocol and add complete handler binding

Configuration · Node.js

TypeScript

import { Interaction } from '@jangts/agent-core/kits/interaction';
const protocol = Interaction.define({
  commandField: 'type', commands: {
    reply: { category: 'presentation', description: '展示已确认说明', fields: { text: { required: true, jsonSchema: { type: 'string' } } }, checks: [{ occur: value => typeof value.text !== 'string', error: 'text 必须是字符串' }] },
    unavailable: { category: 'receipt', description: '说明资料不可用', fields: {} },
  },
});
const dispatcher = Interaction.bind(protocol, {
  reply: value => '说明：' + String(value.text),
  unavailable: () => '资料暂不可用',
});
console.log(dispatcher.dispatch({ type: 'reply', text: '普通对象也能实现接口。' }, undefined));
console.log(dispatcher.catalog);

console.log(dispatcher.catalog);
