Method Detail

getArchitecture

@Stability(value=Stable)
 @NotNull
Architecture getArchitecture()

The system architectures compatible with this lambda function.

getFunctionArn

@Stability(value=Stable)
 @NotNull
String getFunctionArn()

The ARN of the function.

getFunctionName

@Stability(value=Stable)
 @NotNull
String getFunctionName()

The name of the function.

getIsBoundToVpc

@Stability(value=Stable)
 @NotNull
Boolean getIsBoundToVpc()

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

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

getLatestVersion

@Stability(value=Stable)
 @NotNull
IVersion getLatestVersion()

The `$LATEST` version of this function.

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.

getPermissionsNode

@Stability(value=Stable)
 @NotNull
software.constructs.Node getPermissionsNode()

The construct node where permissions are attached.

getResourceArnsForGrantInvoke

@Stability(value=Stable)
 @NotNull
List<String> getResourceArnsForGrantInvoke()

The ARN(s) to put into the resource field of the generated IAM policy for grantInvoke().

This property is for cdk modules to consume only. You should not need to use this property. Instead, use grantInvoke() directly.

getRole

@Stability(value=Stable)
 @Nullable
default IRole getRole()
