Member Function Documentation

access() [1/3]

virtual std::pair<void*, Datatype_uptr> PDI::Datatype::Accessor_base::access ( const Array_datatype &  type, void *  from, std::vector< std::unique_ptr< Accessor_base >>::const_iterator  remaining_begin, std::vector< std::unique_ptr< Accessor_base >>::const_iterator  remaining_end  ) const

virtual

Access function for array datatype.

Parameters

type	a datatype to get access
