Member Function Documentation

◆ Abort()

void UE::FTexture2DStreamIn_DerivedData::Abort ( )
finalprotectedvirtual

Cancel any active async requests. Does not wait!

Reimplemented from FRenderAssetUpdate.

◆ DoBeginIoRequests()

void UE::FTexture2DStreamIn_DerivedData::DoBeginIoRequests ( const FContext &  Context)
protected

Begin the async requests to load the pending mips.

◆ DoCancelIoRequests()

void UE::FTexture2DStreamIn_DerivedData::DoCancelIoRequests ( )
protected

Cancel any active async requests. Does not wait!

◆ DoEndIoRequests()

void UE::FTexture2DStreamIn_DerivedData::DoEndIoRequests ( const FContext &  Context)
protected

Wait until the async requests are complete and clean them up.

◆ DoPollIoRequests()

bool UE::FTexture2DStreamIn_DerivedData::DoPollIoRequests ( const FContext &  Context)
protected

Poll the async requests and return true if they are complete.
