class AbstractSequence : public mindspore::abstract::AbstractBase

Class AbstractSequence describes the abstract value of a tuple or list.

Subclassed by mindspore::abstract::AbstractList, mindspore::abstract::AbstractTuple

Public Functions

Constructor of AbstractSequence.

Parameters

  • elements – [in] A list of abstracts.

  • sequence_nodes – [in] The nodes of tuple/list, usually are MakeTuple/MakeList CNodes or tuple/list ValueNodes.

explicit AbstractSequence(const AbstractBasePtrList &elements, const std::shared_ptr<AnfNodeWeakPtrList> &sequence_nodes)
