Class: abstract KnowledgeBaseBase

Abstract base class for Knowledge Base (regarless the type). Contains methods valid for KBs either created with CDK or imported and applicable to Knowledge Bases of any type.

Constructors

new KnowledgeBaseBase()

new KnowledgeBaseBase(scope, id): KnowledgeBaseBase

Parameters

scope

Construct

id

string

Returns

KnowledgeBaseBase

Overrides

Resource.constructor

Properties

description?

abstract readonly optional description: string

The description of the knowledge base.

Implementation of

IKnowledgeBase.description


env

readonly env: ResourceEnvironment

The environment this resource belongs to. For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

Implementation of

IKnowledgeBase.env

Inherited from

Resource.env


instruction?

abstract readonly optional instruction: string

A narrative instruction of the knowledge base. A Bedrock Agent can use this instruction to determine if it should query this Knowledge Base.

Implementation of

IKnowledgeBase.instruction


knowledgeBaseArn

abstract readonly knowledgeBaseArn: string

The ARN of the knowledge base.

Example

"arn:aws:bedrock:us-east-1:123456789012:knowledge-base/KB12345678"

Implementation of

IKnowledgeBase.knowledgeBaseArn


knowledgeBaseId

abstract readonly knowledgeBaseId: string

The ID of the knowledge base.

Example

"KB12345678"

Implementation of

IKnowledgeBase.knowledgeBaseId


node

readonly node: Node

The tree node.

Implementation of

IKnowledgeBase.node

Inherited from

Resource.node


physicalName

protected readonly physicalName: string

Returns a string-encoded token that resolves to the physical name that should be passed to the CloudFormation resource.

This value will resolve to one of the following:

Inherited from

Resource.physicalName


role

abstract readonly role: IRole

The role associated with the knowledge base.

Implementation of

IKnowledgeBase.role


stack

readonly stack: Stack

The stack in which this resource is defined.

Implementation of

IKnowledgeBase.stack

Inherited from

Resource.stack


type

abstract readonly type: KnowledgeBaseType

The type of knowledge base.

Implementation of

IKnowledgeBase.type

Methods

_enableCrossEnvironment()

_enableCrossEnvironment(): void

Internal

Called when this resource is referenced across environments (account/region) to order to request that a physical name will be generated for this resource during synthesis, so the resource can be referenced through its absolute name/arn.

Returns

void

Inherited from

Resource._enableCrossEnvironment


applyRemovalPolicy()

applyRemovalPolicy(policy): void

Apply the given removal policy to this resource

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters

policy

RemovalPolicy

Returns

void

Implementation of

IKnowledgeBase.applyRemovalPolicy

Inherited from

Resource.applyRemovalPolicy


generatePhysicalName()

protected generatePhysicalName(): string

Returns

string

Inherited from

Resource.generatePhysicalName


getResourceArnAttribute()

protected getResourceArnAttribute(arnAttr, arnComponents): string

Returns an environment-sensitive token that should be used for the resource’s “ARN” attribute (e.g. bucket.bucketArn).

Normally, this token will resolve to arnAttr, but if the resource is referenced across environments, arnComponents will be used to synthesize a concrete ARN with the resource’s physical name. Make sure to reference this.physicalName in arnComponents.

Parameters

arnAttr

string

The CFN attribute which resolves to the ARN of the resource. Commonly it will be called “Arn” (e.g. resource.attrArn), but sometimes it’s the CFN resource’s ref.

arnComponents

ArnComponents

The format of the ARN of this resource. You must reference this.physicalName somewhere within the ARN in order for cross-environment references to work.

Returns

string

Inherited from

Resource.getResourceArnAttribute


getResourceNameAttribute()

protected getResourceNameAttribute(nameAttr): string

Returns an environment-sensitive token that should be used for the resource’s “name” attribute (e.g. bucket.bucketName).

Normally, this token will resolve to nameAttr, but if the resource is referenced across environments, it will be resolved to this.physicalName, which will be a concrete name.

Parameters

nameAttr

string

The CFN attribute which resolves to the resource’s name. Commonly this is the resource’s ref.

Returns

string

Inherited from

Resource.getResourceNameAttribute


grant()

grant(grantee, …actions): Grant

Grant the given principal identity permissions to perform actions on this knowledge base.

Parameters

grantee

IGrantable

string[]

Returns

Grant

Implementation of

IKnowledgeBase.grant


grantQuery()

grantQuery(grantee): Grant

Grant the given identity permissions to query the knowledge base. This contains:

Parameters

grantee

IGrantable

Returns

Grant

Implementation of

IKnowledgeBase.grantQuery


grantRetrieve()

grantRetrieve(grantee): Grant

Grant the given identity permissions to retrieve content from the knowledge base.

Parameters

grantee

IGrantable

Returns

Grant


grantRetrieveAndGenerate()

grantRetrieveAndGenerate(grantee): Grant

Grant the given identity permissions to retrieve content from the knowledge base.

Parameters

grantee

IGrantable

Returns

Grant


toString()

toString(): string

Returns a string representation of this construct.

Returns

string

Inherited from

Resource.toString


isConstruct()

static isConstruct(x): x is Construct

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters

x

any

Any object

Returns

x is Construct

true if x is an object created from a class which extends Construct.

Inherited from

Resource.isConstruct


isOwnedResource()

static isOwnedResource(construct): boolean

Returns true if the construct was created by CDK, and false otherwise

Parameters

IConstruct

Returns

boolean

Inherited from

Resource.isOwnedResource


isResource()

static isResource(construct): construct is Resource

Check whether the given construct is a Resource

Parameters

construct

IConstruct

Returns

construct is Resource

Resource.isResource
