# KnowledgeBaseReflection

Provides read-only reflection on the configuration of a Bedrock knowledge base underlying `CfnKnowledgeBase` resource.

Use `KnowledgeBaseReflection.of()` to obtain an instance from any KnowledgeBase reference.
All getters read directly from the L1 resource, providing a single source of
truth regardless of whether the knowledge base was created as an L2, imported, or
constructed directly as a CfnKnowledgeBase.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`bedrock/knowledge-bases/knowledge-base-reflection.ts`](https://github.com/aws/aws-cdk/blob/v2.274.0-alpha.0/packages/@aws-cdk/aws-bedrock-alpha/bedrock/knowledge-bases/knowledge-base-reflection.ts#L14)
- Type last changed: v2.274.0-alpha.0 · 21 Oct 2026

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as bedrock_alpha from '@aws-cdk/aws-bedrock-alpha';
import { aws_bedrock as interfaces_bedrock } from 'aws-cdk-lib/interfaces';

declare const knowledgeBaseRef: interfaces_bedrock.IKnowledgeBaseRef;
const knowledgeBaseReflection = bedrock_alpha.KnowledgeBaseReflection.of(knowledgeBaseRef);
```

## Properties

- `knowledgeBase`: [CfnKnowledgeBase](/cdk/api/v2/docs/aws-cdk-lib.aws_bedrock.CfnKnowledgeBase.html) (required) — The underlying L1 knowledge base resource.

## Methods

- `of(knowledgeBaseRef: IKnowledgeBaseRef): KnowledgeBaseReflection // chainable` (static) — Creates a reflection facade for a knowledge base reference.
