Class foreign_storage::PassThroughBuffer¶

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 a const pointer.
