// How should the S3 Action detect changes.
//
// This is the type of the `S3SourceAction.trigger` property.
//
// Example:
//   import "github.com/aws/aws-cdk-go/awscdk"
//
//   var sourceBucket bucket
//
//   sourceOutput := codepipeline.NewArtifact()
//   key := "some/key.zip"
//   trail := cloudtrail.NewTrail(this, jsii.String("CloudTrail"))
//   trail.AddS3EventSelector([]s3EventSelector{
//   	&s3EventSelector{
//   		Bucket: sourceBucket,
//   		ObjectPrefix: key,
//   	},
//   }, &AddEventSelectorOptions{
//   	ReadWriteType: cloudtrail.ReadWriteType_WRITE_ONLY,
//   })
//   sourceAction := codepipeline_actions.NewS3SourceAction(&S3SourceActionProps{
//   	ActionName: jsii.String("S3Source"),
//   	BucketKey: key,
//   	Bucket: sourceBucket,
//   	Output: sourceOutput,
//   	Trigger: codepipeline_actions.S3Trigger_EVENTS,
