(experimental) Imports a Layer that has been defined externally.

Parameters:

scope - the parent Construct that will use the imported layer. This parameter is required.

id - the id of the imported layer in the construct tree. This parameter is required.

attrs - the properties of the imported layer. This parameter is required.

addPermission

@Stability(value=Experimental)
public void addPermission(@NotNull
                                                         String id,

                                                         LayerVersionPermission permission)

(experimental) Add permission for this layer version to specific entities.

Usage within the same account where the layer is defined is always allowed and does not require calling this method. Note that the principal that creates the Lambda function using the layer (for example, a CloudFormation changeset execution role) also needs to have the lambda:GetLayerVersion permission on the layer version.

Specified by:

addPermission in interface ILayerVersion

Parameters:

id - This parameter is required.

permission - This parameter is required.

getLayerVersionArn

@Stability(value=Experimental)
 @NotNull
public String getLayerVersionArn()

(experimental) The ARN of the Lambda Layer version that this Layer defines.

Specified by:

getLayerVersionArn in interface ILayerVersion

getCompatibleRuntimes

@Stability(value=Experimental)
 @Nullable
public List<Runtime> getCompatibleRuntimes()

(experimental) The runtimes compatible with this Layer.

Specified by:

getCompatibleRuntimes in interface ILayerVersion
