Syntax

class FBufferReaderWithSHA : public FBufferReaderBase

Remarks

Similar to FBufferReader, but will verify the contents of the buffer on close (on close to that we know we don't need the data anymore)

Variables

Name Description

Protected variable

bool

 

bIsUnfoundHashAnError

True if failing to lookup the hash should trigger an error

Constructors

Name Description

Public function

FBufferReaderWithSHA

(
    void* Data,
    int64 Size,
    bool bInFreeOnClose,
    const TCHAR* SHASourcePathname,
    bool bIsPersistent,
    bool bInIsUnfoundHashAnError
)

We force the base class to NOT free buffer on close, as we will let the SHA task do it if needed
