pure virtual

load the data content into DType, the caller can pass in NULL or an existing address when inout_dptr is NULL: producer need to allocate a DType and fill the content when inout_dptr is specified producer takes need to fill the content into address specified inout_dptr, or delete the one and create a new one

Parameters

inout_dptr

used to pass in the data holder cell and return the address of the cell filled

Returns

true if there is next record, false if we reach the end
