Optional Element Summary

Optional Elements

Modifier and Type	Optional Element and Description
String	functionName The name of the function to invoke for this annotated method.
String	invocationType The type of invocation to use (one of 'RequestResponse', 'Event', or 'DryRun').
String	logType The type of log to request from the service, either 'None' as default or 'Tail'.
String	qualifier The version or alias name of the function to invoke for this annotated method.

Element Detail

functionName

public abstract String functionName

The name of the function to invoke for this annotated method. If not explicitly assigned, we use the name of the interface method.

Default:

""

invocationType

public abstract String invocationType

The type of invocation to use (one of 'RequestResponse', 'Event', or 'DryRun'). If not explicitly specified, we use 'RequestResponse' unless the method's return type is void, in which case we use 'Event'.

Default:

"RequestResponse"

logType

public abstract String logType

The type of log to request from the service, either 'None' as default or 'Tail'. If set to other than 'None', the invocation type will be 'RequestResponse' regardless of any explicit setting.

When specified, the log information returned by the Lambda function will be emitted to the JCL log for the interface class at the INFO level.

Default:

"None"

qualifier

public abstract String qualifier

The version or alias name of the function to invoke for this annotated method. If you specify function version, the API uses qualified function ARN to invoke a specific Lambda function. If you specify alias name, the API uses the alias ARN to invoke the Lambda function version to which the alias points. If the qualifier isn't specified, then the API invokes the Lambda function with unqualified function ARN which results in invocation of the $LATEST version.

Default:

""
