Member Function Documentation

OnAcceptedNewRequirements()

virtual void DeltaStats::FNoCloudChunkSourceStat::OnAcceptedNewRequirements ( const TSet< FGuid > &  ChunkIds )

inlineoverridevirtual

Called when a batch of chunks are added and accepted via IChunkSource::AddRuntimeRequirements.

Parameters

ChunkIds

The ids of each chunk.

Implements BuildPatchServices::ICloudChunkSourceStat.

OnActiveRequestCountUpdated()

virtual void DeltaStats::FNoCloudChunkSourceStat::OnActiveRequestCountUpdated ( uint32  RequestCount )

inlineoverridevirtual

Called whenever the current number of active requests updates.

Parameters

RequestCount

The number of currently active requests, this will range between 0 and NumSimultaneousDownloads config.

Implements BuildPatchServices::ICloudChunkSourceStat.

OnDownloadAborted()

virtual void DeltaStats::FNoCloudChunkSourceStat::OnDownloadAborted ( const FGuid &  ChunkId, const FString &  Url, double  DownloadTimeMean, double  DownloadTimeStd, double  DownloadTime, double  BreakingPoint  )

inlineoverridevirtual

Called whenever a chunk was aborted because it was determined as taking too long.

Parameters

ChunkId	The id of the chunk.
Url	The url used to request the chunk.
DownloadTimeMean	The current mean time for chunk downloads when this abort was made.
DownloadTimeStd	The current standard deviation for chunk download times when this abort was made.
DownloadTime	The time this request had been running for.
BreakingPoint	The calculated breaking point which this request has overran.

Implements BuildPatchServices::ICloudChunkSourceStat.

OnDownloadCorrupt()

virtual void DeltaStats::FNoCloudChunkSourceStat::OnDownloadCorrupt ( const FGuid &  ChunkId, const FString &  Url, BuildPatchServices::EChunkLoadResult  LoadResult  )

inlineoverridevirtual

OnDownloadFailed()

virtual void DeltaStats::FNoCloudChunkSourceStat::OnDownloadFailed ( const FGuid &  ChunkId, const FString &  Url  )

inlineoverridevirtual

Called whenever a chunk download request has failed.

Parameters

ChunkId	The id of the chunk.
Url	The url used to request the chunk.

Implements BuildPatchServices::ICloudChunkSourceStat.

OnDownloadHealthUpdated()

virtual void DeltaStats::FNoCloudChunkSourceStat::OnDownloadHealthUpdated ( EBuildPatchDownloadHealth  DownloadHealth )

inlineoverridevirtual

Called whenever the perceived download health changes, according to the provided configuration.

Parameters

DownloadHealth

The new download health value.

Implements BuildPatchServices::ICloudChunkSourceStat.

OnDownloadRequested()

virtual void DeltaStats::FNoCloudChunkSourceStat::OnDownloadRequested ( const FGuid &  ChunkId )

inlineoverridevirtual

Called whenever a chunk download request is made.

Parameters

ChunkId

The id of the chunk.

Implements BuildPatchServices::ICloudChunkSourceStat.

OnDownloadSuccess()

virtual void DeltaStats::FNoCloudChunkSourceStat::OnDownloadSuccess ( const FGuid &  ChunkId )

inlineoverridevirtual

Called whenever a chunk download request has succeeded.

Parameters

ChunkId

The id of the chunk.

Implements BuildPatchServices::ICloudChunkSourceStat.

OnReceivedDataUpdated()

virtual void DeltaStats::FNoCloudChunkSourceStat::OnReceivedDataUpdated ( int64  TotalBytes )

inlineoverridevirtual

Called to update the amount of bytes which have been downloaded.

Parameters

TotalBytes

The number of bytes downloaded so far.

Implements BuildPatchServices::ICloudChunkSourceStat.

OnRequiredDataUpdated()

virtual void DeltaStats::FNoCloudChunkSourceStat::OnRequiredDataUpdated ( int64  TotalBytes )

inlineoverridevirtual

Called whenever the total number of bytes intended to download updates. This can occur after initialization if a chunk is requested which was not in the original list.

Parameters

TotalBytes

The number of bytes downloaded so far.

Implements BuildPatchServices::ICloudChunkSourceStat.

OnSuccessRateUpdated()

virtual void DeltaStats::FNoCloudChunkSourceStat::OnSuccessRateUpdated ( float  SuccessRate )

inlineoverridevirtual

Called whenever the success rate of requests has been updated.

Parameters

SuccessRate

The new success rate value, when 1.0 is all requests made so far have been successful, and 0.0 is all requests failed so far.

Implements BuildPatchServices::ICloudChunkSourceStat.
