// GetContentModerationRequest returns a request value for making API operation for

//
// Gets the unsafe content analysis results for a Amazon Rekognition Video analysis
// started by StartContentModeration.
//
// Unsafe content analysis of a video is an asynchronous operation. You start
// analysis by calling StartContentModeration which returns a job identifier
// (JobId). When analysis finishes, Amazon Rekognition Video publishes a completion
// status to the Amazon Simple Notification Service topic registered in the
// initial call to StartContentModeration. To get the results of the unsafe
// content analysis, first check that the status value published to the Amazon
// SNS topic is SUCCEEDED. If so, call GetContentModeration and pass the job
// identifier (JobId) from the initial call to StartContentModeration.
//
// For more information, see Working with Stored Videos in the Amazon Rekognition
// Devlopers Guide.
//
// GetContentModeration returns detected unsafe content labels, and the time
// they are detected, in an array, ModerationLabels, of ContentModerationDetection
// objects.
//
// By default, the moderated labels are returned sorted by time, in milliseconds
// from the start of the video. You can also sort them by moderated label by
// specifying NAME for the SortBy input parameter.
//
// Since video analysis can return a large number of results, use the MaxResults
// parameter to limit the number of labels returned in a single call to GetContentModeration.
// If there are more results than specified in MaxResults, the value of NextToken
// in the operation response contains a pagination token for getting the next
// set of results. To get the next page of results, call GetContentModeration
// and populate the NextToken request parameter with the value of NextToken
// returned from the previous call to GetContentModeration.
//
// For more information, see Detecting Unsafe Content in the Amazon Rekognition
// Developer Guide.
