@cdklabs/generative-ai-cdk-constructs / bedrock / DataSource
Specifies the base class for all data source resources (imported and new).
readonly
dataSourceId:string
The unique identifier of the data source.
'JHUEVXUZMU'
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.
readonly
node:Node
The tree node.
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:
- a concrete value (e.g.
"my-awesome-bucket"
) undefined
, when a name should be generated by CloudFormation- a concrete name generated automatically during synthesis, in cross-environment scenarios.
readonly
stack:Stack
The stack in which this resource is defined.
_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.
void
DataSourceBase
._enableCrossEnvironment
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
).

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
.
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
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.
string
DataSourceBase
.getResourceArnAttribute
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.
string
The CFN attribute which resolves to the resource's name.
Commonly this is the resource's ref
.

.getResourceNameAttribute

Returns a string representation of this construct.

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.
any
Any object
x is Construct
true if x
is an object created from a class which extends Construct
.
static
isOwnedResource(construct
):boolean
Returns true if the construct was created by CDK, and false otherwise
