      • vpcConfig

        public final VpcConfig vpcConfig()

        For network connectivity to Amazon Web Services resources in a VPC, specify a list of security groups and subnets in the VPC. When you connect a function to a VPC, it can access resources and the internet only through that VPC. For more information, see Configuring a Lambda function to access resources in a VPC.

      • runtime

        public final Runtime runtime()

        The identifier of the function's runtime. Runtime is required if the deployment package is a .zip file archive. Specifying a runtime results in an error if you're deploying a function using a container image.

        The following list includes deprecated runtimes. Lambda blocks creating new functions and updating existing functions shortly after each runtime is deprecated. For more information, see Runtime use after deprecation.

        For a list of all currently supported runtimes, see Supported runtimes.

        If the service returns an enum value that is not available in the current SDK version, runtime will return Runtime.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from runtimeAsString().

        Returns:
        The identifier of the function's runtime. Runtime is required if the deployment package is a .zip file archive. Specifying a runtime results in an error if you're deploying a function using a container image.

      • deadLetterConfig

        public final DeadLetterConfig deadLetterConfig()

        A dead-letter queue configuration that specifies the queue or topic where Lambda sends asynchronous events when they fail processing. For more information, see Dead-letter queues.

        Returns:
        A dead-letter queue configuration that specifies the queue or topic where Lambda sends asynchronous events when they fail processing. For more information, see Dead-letter queues.

      • tracingConfig

        public final TracingConfig tracingConfig()

        Set Mode to Active to sample and trace a subset of incoming requests with X-Ray.

        Returns:
        Set Mode to Active to sample and trace a subset of incoming requests with X-Ray.

      • revisionId

        public final String revisionId()

        Update the function only if the revision ID matches the ID that's specified. Use this option to avoid modifying a function that has changed since you last read it.

        Returns:
        Update the function only if the revision ID matches the ID that's specified. Use this option to avoid modifying a function that has changed since you last read it.

      • hasLayers

        public final boolean hasLayers()
        For responses, this returns true if the service returned a value for the Layers property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • layers

        public final List<String> layers()

        A list of function layers to add to the function's execution environment. Specify each layer by its ARN, including the version.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasLayers() method.

        Returns:
        A list of function layers to add to the function's execution environment. Specify each layer by its ARN, including the version.

      • hasFileSystemConfigs

        public final boolean hasFileSystemConfigs()
        For responses, this returns true if the service returned a value for the FileSystemConfigs property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • fileSystemConfigs

        public final List<FileSystemConfig> fileSystemConfigs()

        Connection settings for an Amazon EFS file system.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasFileSystemConfigs() method.

        Returns:
        Connection settings for an Amazon EFS file system.

      • ephemeralStorage

        public final EphemeralStorage ephemeralStorage()

        The size of the function's /tmp directory in MB. The default value is 512, but can be any whole number between 512 and 10,240 MB. For more information, see Configuring ephemeral storage (console).

        Returns:
        The size of the function's /tmp directory in MB. The default value is 512, but can be any whole number between 512 and 10,240 MB. For more information, see Configuring ephemeral storage (console).

      • loggingConfig

        public final LoggingConfig loggingConfig()

        The function's Amazon CloudWatch Logs configuration settings.

        Returns:
        The function's Amazon CloudWatch Logs configuration settings.

      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
