Member Function Documentation

GetBytesDownloaded()

uint64 BuildPatchServices::FDownloadServiceStatistics::GetBytesDownloaded ( ) const

overridevirtual

Returns

the total number of bytes downloaded.

Implements BuildPatchServices::IDownloadServiceStatistics.

GetCurrentDownloads()

TArray< FDownload > BuildPatchServices::FDownloadServiceStatistics::GetCurrentDownloads ( ) const

overridevirtual

Returns

an array of current request info.

Implements BuildPatchServices::IDownloadServiceStatistics.

GetImmediateAverageSpeedPerRequest()

TPair< double, uint32 > BuildPatchServices::FDownloadServiceStatistics::GetImmediateAverageSpeedPerRequest ( uint32  MinCount )

overridevirtual

Calculates the average speed per request since the last time this function was called. NOT A CUMULATIVE AVERAGE

Parameters

MinCount

– The smallest number of samples that will be used for calculating an average; if the minimum count isn't met, the same value as the previous call is returned, and the samples will continue to accumulate.

Returns

A pair containing an average of the per-request download speed SINCE THIS FUNCTION WAS LAST CALLED and the count of requests completed since the last call.

Implements BuildPatchServices::IDownloadServiceStatistics.

GetNumCurrentDownloads()

int32 BuildPatchServices::FDownloadServiceStatistics::GetNumCurrentDownloads ( ) const

overridevirtual

Returns

the number of current requests.

Implements BuildPatchServices::IDownloadServiceStatistics.

GetNumFailedChunkDownloads()

int32 BuildPatchServices::FDownloadServiceStatistics::GetNumFailedChunkDownloads ( ) const

overridevirtual

Returns

the number of chunk requests that failed.

Implements BuildPatchServices::IDownloadServiceStatistics.

GetNumSuccessfulChunkDownloads()

int32 BuildPatchServices::FDownloadServiceStatistics::GetNumSuccessfulChunkDownloads ( ) const

overridevirtual

Returns

the number of successfully downloaded chunks.

Implements BuildPatchServices::IDownloadServiceStatistics.

OnDownloadComplete()

void BuildPatchServices::FDownloadServiceStatistics::OnDownloadComplete ( const FDownloadRecord &  DownloadRecord )

overridevirtual

Called for each request completion.

Parameters

DownloadRecord

The struct containing the stats for this request.

Implements BuildPatchServices::IDownloadServiceStat.

OnDownloadProgress()

void BuildPatchServices::FDownloadServiceStatistics::OnDownloadProgress ( int32  RequestId, uint64  BytesReceived  )

overridevirtual

Called for each request completion.

Parameters

RequestId	The id for the request.
BytesReceived	The bytes received so far.

Implements BuildPatchServices::IDownloadServiceStat.

OnDownloadStarted()

void BuildPatchServices::FDownloadServiceStatistics::OnDownloadStarted ( int32  RequestId, const FString &  Uri  )

overridevirtual

Called as each request has started.

Parameters

RequestId	The id for the request.
Uri	The uri for the request.

Implements BuildPatchServices::IDownloadServiceStat.

Reset()
