Member Function Documentation

◆ GetArchiveName()

virtual FString FLargeMemoryReader::GetArchiveName ( ) const
overridevirtual

Returns the name of the Archive. Useful for getting the name of the package a struct or object is in when a loading error occurs.

This is overridden for the specific Archive Types

Reimplemented from FMemoryArchive.

◆ operator=()

FLargeMemoryReader & FLargeMemoryReader::operator= ( const FLargeMemoryReader & )
privatedelete

◆ Serialize()

virtual void FLargeMemoryReader::Serialize ( void * OutData,
int64 Num )
overridevirtual

Reimplemented from FArchive.

◆ TotalSize()

virtual int64 FLargeMemoryReader::TotalSize ( )
overridevirtual

Gets the total size of the data buffer

Reimplemented from FArchive.
