Interface: IGraphKnowledgeBase

                        COMMON INTERFACES

Properties

description?

readonly optional description?: string

The description of the knowledge base.

env

readonly env: ResourceEnvironment

The environment this resource belongs to.

For resources that are created and managed in a Stack (those created by creating new class instances like new Role(), new Bucket(), etc.), this is always the same as the environment of the stack they belong to.

For referenced resources (those obtained from referencing methods like Role.fromRoleArn(), Bucket.fromBucketName(), etc.), they might be different than the stack they were imported into.

Methods

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).

grant(grantee, ...actions): Grant

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

grantQuery(grantee): Grant

Grant the given identity permissions to query the knowledge base.

with(...mixins): IConstruct

Applies one or more mixins to this construct.

Mixins are applied in order. The list of constructs is captured at the start of the call, so constructs added by a mixin will not be visited.
