Detailed Description

template<typename AccessType>
class ddl::codec::DecoderElementAccess< AccessType >

A element access type concept template to retrieve element information from the AccessType and get the element value.

This class is to retrieve common information of the element and get the element value content.

DecoderElement.

Template Parameters

AccessType

The AccessType for the element (Codec, Decoder, etc. )

Definition at line 840 of file codec_iterator.h.

Member Function Documentation
