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, String requestId, String invokedFunction, String region, String executionEnv, String accessKey, String secretAccessKey, String sessionToken})

Properties

accessKey ↔ String: Access key that is acquired via STS.
read / write
executionEnv ↔ String: The execution environment of the function.
read / write
functionMemorySize ↔ String: Memory sized that is allocated to execution of the function.
read / write
functionName ↔ String: Name of the function that is invoked.
read / write
functionVersion ↔ String: Version of the function that is invoked.
read / write
handler ↔ String: Handler that is used for the invocation of the function
read / write
hashCode → int: The hash code for this object. [...]
read-only, inherited
invokedFunctionArn ↔ String: The ARN to identify the function.
read / write
logGroupName ↔ String: Cloudwatch LogGroup that is associated with the Lambda.
read / write
logStreamName ↔ String: Cloudwach LogStream that is associated with the Lambda.
read / write
region ↔ String: Region that this function exists in.
read / write
requestId ↔ String: Id of the request. You can use this to track the request for the invocation.
read / write
runtimeType → Type: A representation of the runtime type of the object.

Methods

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 non-existent method or property is accessed. [...]
inherited
toString() → String: Returns a string representation of this object.
inherited

Operators

operator ==(Object other) → bool: The equality operator. [...]
inherited

Static Methods

fromNextInvocation(NextInvocation nextInvocation) → dynamic: Creates a new Context from NextInvocation which is the data from the Lambda Runtime Interface for the next Handler<T> invocation.
