class FNboSerializeFromBuffer

Remarks

Class used to read data from a NBO data buffer

Variables

	Name	Description
bool	bHasOverflowed	Indicates whether reading from the buffer caused an overflow or not
int32	CurrentOffset	The current location in the byte stream for reading
const uint8 ...	Data	Pointer to the data this reader is attached to
const int32	NumBytes	The size of the data in bytes
