access()

std::pair<void*, Datatype_uptr> PDI::Array_datatype::Slice_accessor::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

overridevirtual

Access function for array datatype.

Parameters

type	a datatype to get access
from	pointer to data of type datatype
remaining_begin	iterator to the beginning of remaining accessors
remaining_end	iterator to the end of remaining accessors

Returns

string that inform what access is made

Reimplemented from PDI::Datatype::Accessor_base.

clone()

std::unique_ptr<Accessor_base> PDI::Array_datatype::Slice_accessor::clone ( ) const

overridevirtual

Creates and returns clone of accessor.

Returns

clone of accessor

Implements PDI::Datatype::Accessor_base.
