void ExtractBufferState ( int32& ValidCount,
int32& NextIterator
) const

   RewindData.h  

const bool GetHeadFrameAndPhase ( FFrameAndPhase& OutFrameAndPhase
) const

 Get the FrameAndPhase of the head / last entry. RewindData.h  

T & Insert ( const FFrameAndPhase FrameAndPhase,
FDirtyPropertiesPool& Manager
)

   RewindData.h  

bool IsClean ( const FFrameAndPhase FrameAndPhase
) const

   RewindData.h  

bool IsEmpty()

   RewindData.h  

bool IsInSync ( const THandle& Handle,
const FFrameAndPhase FrameAndPhase,
const FDirtyPropertiesPool& Pool
) const

   RewindData.h  

const T * Read ( const FFrameAndPhase FrameAndPhase,
const FDirtyPropertiesPool& Manager
) const

 Searches in reverse order for interval that contains FrameAndPhase. RewindData.h  

void Release ( FDirtyPropertiesPool& Manager
)

 Releases data back into the pool. RewindData.h  

void Reset()

   RewindData.h  

void RestoreBufferState ( const int32& ValidCount,
const int32& NextIterator
)

   RewindData.h  

T & WriteAccessMonotonic ( const FFrameAndPhase FrameAndPhase,
FDirtyPropertiesPool& Manager
)

 Gets access into buffer in monotonically increasing FrameAndPhase order: x_{n+1} > x_n. RewindData.h  

T * WriteAccessNonDecreasing ( const FFrameAndPhase FrameAndPhase,
FDirtyPropertiesPool& Manager
)

 Gets access into buffer in non-decreasing FrameAndPhase order: x_{n+1} >= x_n If x_{n+1} == x_n we return null to inform the user (usefull when a single phase can have multiple writes) RewindData.h
