Constructors

FunctionBase(ByRefValue)

Used by jsii to construct an instance of this class from a Javascript-owned object reference

protected FunctionBase(ByRefValue reference)

Parameters

reference Amazon.JSII.Runtime.Deputy.ByRefValue: The Javascript-owned object reference

FunctionBase(DeputyBase.DeputyProps)

Used by jsii to construct an instance of this class from DeputyProps

protected FunctionBase(DeputyBase.DeputyProps props)

Parameters

props Amazon.JSII.Runtime.Deputy.DeputyBase.DeputyProps: The deputy props

FunctionBase(Construct, String, IResourceProps)

protected FunctionBase(Construct scope, string id, IResourceProps props = null)

Parameters

scope Constructs.Construct
id System.String
props IResourceProps

Properties

CanCreatePermissions

Whether the addPermission() call adds any permissions.

protected abstract bool CanCreatePermissions { get; }

Property Value

System.Boolean

Remarks

True for new Lambdas, false for version $LATEST and imported Lambdas from different accounts.

Connections

Access the Connections object.

public virtual Connections_ Connections { get; }

Property Value

Connections_

Remarks

Will fail if not a VPC-enabled Lambda Function

FunctionArn

The ARN fo the function.

public abstract string FunctionArn { get; }

Property Value

System.String

FunctionName

The name of the function.

public abstract string FunctionName { get; }

Property Value

System.String

GrantPrincipal

The principal this Lambda Function is running as.

public abstract IPrincipal GrantPrincipal { get; }

Property Value

IPrincipal

IsBoundToVpc

Whether or not this Lambda function was bound to a VPC.

public virtual bool IsBoundToVpc { get; }

Property Value

System.Boolean

Remarks

If this is is false, trying to access the connections object will fail.

LatestVersion

The $LATEST version of this function.

public virtual IVersion LatestVersion { get; }

Property Value

IVersion

Remarks

Note that this is reference to a non-specific AWS Lambda version, which means the function this version refers to can return different results in different invocations.

To obtain a reference to an explicit version which references the current function configuration, use lambdaFunction.currentVersion instead.

PermissionsNode

The construct node where permissions are attached.

public abstract ConstructNode PermissionsNode { get; }

Property Value

ConstructNode

Role

The IAM role associated with this function.

public abstract IRole Role { get; }

Property Value

IRole

Remarks

Undefined if the function was imported without a role.

Methods

AddEventSource(IEventSource)

Adds an event source to this function.

public virtual void AddEventSource(IEventSource source)

Parameters

source IEventSource

Remarks

Event sources are implemented in the @aws-cdk/aws-lambda-event-sources module.

The following example adds an SQS Queue as an event source:

import { SqsEventSource } from '@aws-cdk/aws-lambda-event-sources';
myFunction.addEventSource(new SqsEventSource(myQueue));

AddEventSourceMapping(String, IEventSourceMappingOptions)

Adds an event source that maps to this AWS Lambda function.

public virtual EventSourceMapping AddEventSourceMapping(string id, IEventSourceMappingOptions options)

Parameters

id System.String
options IEventSourceMappingOptions

Returns

EventSourceMapping

AddPermission(String, IPermission)

Adds a permission to the Lambda resource policy.

public virtual void AddPermission(string id, IPermission permission)

Parameters

id System.String: The id for the permission construct.
permission IPermission: The permission to grant to this Lambda function.

Remarks

See: Permission for details.

public virtual void AddToRolePolicy(PolicyStatement statement)

Parameters

statement PolicyStatement
