Context class

Context contains the Lambda execution context information. They are either provided via Platform.environment or NextInvocation which is the result from the Lambda API.

Note: this should not be used directly.

Constructors

Context({String? handler, String? functionName, String? functionMemorySize, String? logGroupName, String? logStreamName, required String requestId, String? invokedFunction, String? region, String? executionEnv, String? accessKey, String? secretAccessKey, String? sessionToken})

Properties

accessKey ↔ String?

Access key that is acquired via STS.

getter/setter pair

executionEnv ↔ String?

The execution environment of the function.

getter/setter pair

functionMemorySize ↔ String?

Memory sized that is allocated to execution of the function.

getter/setter pair

functionName ↔ String?

Name of the function that is invoked.

getter/setter pair

functionVersion ↔ String?

Version of the function that is invoked.

getter/setter pair

handler ↔ String?

Handler that is used for the invocation of the function

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

invokedFunctionArn ↔ String?

The ARN to identify the function.

getter/setter pair

logGroupName ↔ String?

Cloudwatch LogGroup that is associated with the Lambda.

getter/setter pair

logStreamName ↔ String?

Cloudwach LogStream that is associated with the Lambda.

getter/setter pair

region ↔ String?

Region that this function exists in.

getter/setter pair

requestId ↔ String?

copyWith({String? handler, String? functionName, String? functionMemorySize, String? logGroupName, String? logStreamName, String? requestId, String? invokedFunction, String? region, String? executionEnv, String? accessKey, String? secretAccessKey, String? sessionToken}) → Context

Allows to copy a created Context over with some new settings.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

fromNextInvocation(NextInvocation nextInvocation) → Context

Creates a new Context from NextInvocation which is the data from the Lambda Runtime Interface for the next Handler<T> invocation.
