class
PassThroughBuffer
: public Data_Namespace::AbstractBuffer¶ PassThroughBuffer
wraps a pointer with specifed data size. This class does not take ownership of the pointer. The underlying buffer is never intended to be modified only read, hence the constructor takes aconst
pointer.Public Functions
